Transmitter Antenna

A 2" antenna is supplied with the 2300NCP EXPANDABLE transmitter. The antenna must be fastened to the transmitter before using the unit.

Rheostat Dial

The Rheostat Dial is located on the top of the transmitter: (0) being the lowest level and (127) being the highest. The LCD screen shows the intensity level during operation.

LCD Screen

The LCD screen indicates the stimulation level (0-127) on the screen. The battery life indicator shows:

  • 3 bars = full charge
  • 2 bars = medium charge
  • 1 bar = needs charge

The battery life indicator only shows the remainingcharge of your transmitter. To find the remaining chargefor your receiver, observe the LED indicator lighton the receiver.

Care for LCD Transmitters in Cold Temperature

In cold temperatures (10°F or below), the Liquid Crystal Display (LCD) on your transmitter may be dim or slow to respond. Wait until the display becomes visible before selecting any training level.

Even though the LCD screen might be dim or slow to respond, when you push the Nick or Constant button, the transmitter will still function properly. In the occurrence of extremely cold weather, the LCD screen might take a moment to respond causing the intensity level to freeze at that current level.

If you turn the Rheostat Dial, the level on the screen may not change but the actual intensity from the receiver will change in agreement with the dial.

In this situation, it is ideal to either wait until your transmitter is back to working order before emitting a correction or while holding the Constant button down, slowly turn the Rheostat Dial while watching your dog's reaction.

Do not turn the Rheostat Dial rapidly because the receiver will emit a static correction based on the level of the Rheostat Dial, which might not be correctly reflected on the LCD screen.

Attention! When using the unit in cold temperatures, it is recommended that the transmitter is placed under your jacket next to your body. The warmth of your body will greatly improve the battery life and usage.

Transmitter Indicator Light

The transmitter LED indicator light is located near the Rheostat Dial. It will flash every 5 seconds when the transmitter has been turned on.

The LED indicator color indicates the battery life level.

  • Green = Full charge
  • Amber = Medium charge
  • Red = Needs charge

If the unit is used while the LED indicator is red, it mayshut down automatically.

Transmitter Battery Charging Receptacle & Rubber Plug

Located on the backside of the transmitter, the chargingreceptacle is covered by a rubber plug. Insert one end of the battery charging cable into the receptacle to charge the battery. After charging is complete, close the receptacle with its rubber plug to make sure dirt or water does not get inside.



The transmitter for the 2300NCP EXPANDABLEunit has four buttons and a toggle switch on the transmitter (one on the face of the transmitter, two on the left side, and one on the right side).

1-Dog/2-Dog Toggle Switch

The 1-Dog/2-Dog Toggle Switch is located on the front of the transmitter. Use the toggle switch to control up to 2 dogs when 2 receivers are coded to the handheld transmitter. When the toggle switch is set to the up position, the transmitter will control the black receiver. When the toggle switch is set to the down position, the transmitter will control the orange receiver.

Nick Button

The Nick button is located on the top left side of the handheld transmitter. When the Nick button is pressed, the receiver emits a single rapid pulse of electrical stimulation.

Constant Button

The Constant button is located on the bottom of the leftside of the handheld transmitter. Pressing the Constantbutton gives continuous stimulation as long as thebutton is pressed, for up to 12 seconds. If the buttonis not released after 12 seconds, the stimulation willautomatically turn off as a safety feature. The receiver will be ready to be reactivated once the button has beenreleased.

Pager Button

The Pager button is located on the face of the transmitter. Pressing it will give a vibration as long as the button is pressed, for up to 12 seconds.

On/Off Button

The on/off button is located on the right side of the transmitter.


Receiver On/Off Magnetic Red Dot

To turn on the receiver, place the magnetic red dot on the back of the transmitter to the red dot on the receiver. Hold the two red dots together for a moment until the LED light on the receiver comes on.

To turn off the unit, repeat the same procedure holdingthe two red dots together momentarily. The LED light will turn red for a brief moment indicating that the receiver has now shut off.

Receiver Indicator Light

Located on the front of the receiver, the indicator light comes on and blinks once every 4 seconds after the receiver has been turned on. The color of the LED indicates the battery life of the receiver.

  • Green = Full charge
  • Amber = Medium charge
  • Red = Needs charge

When the Constant button on the transmitter is pressed, the receiver indicator light will glow steadily (either green, amber, or red based on the remaining battery life), as long as you hold the button down, for up to 12 seconds.

When the Nick button is pressed, the light comes on for a fraction of a second.


The Dogtra 2300NCP uses a lithium polymer battery. Recharge the unit if the indicator light is red or does not come on, the transmitter LCD shows only 1 bar on the indicator, or the system will not stay on when any button is pressed.

Note 1: Only use Dogtra-approved batteries, chargers, and accessories for your Dogtra e-collars. This will prevent any damage that can be incurred from attempting to use a different charger.

Note 2: The unit has a partial charge when it leaves the Dogtra facility. Upon receipt of the system, be sure to give it a full 2-hour initial charge before the first use away from any flammable substances.

Note 3: When a charger is not in use, disconnect it from the power source. Fully charge the batteries if the unit is to be stored without use for a period of 3 months or more.

Follow the steps below to charge your system:

  1. Open the rubber plugs on the battery charging receptacles and plug in the charging cable.
  2. Plug the charger into a 120-volt wall outlet or, if using the auto charger, plug into a cigarette lighter only for lithium polymer batteries (use a 220 volt European charger for Europe). All indicator lights should glow red when properly plugged in and the unit will automatically shut off during the charging process. You will need to turn the unit on again before use once the unit is fully charged and unplugged from the battery cable.
  3. The lithium polymer battery is fully charged within 2 hours. The lights will stay red during the charging process and turn green once the unit is fully charged.
  4. After charging, cover the battery charging receptacles with the rubber plugs.


  1. Turn on the receiver by placing the magnetic red dot on the back of the transmitter to the red dot on the receiver. The indicator light will come on for a moment then blink once every 4 seconds, showing that the receiver is ready to use (the receiver needs to be charged if the indicator light is red).
  2. Turn the transmitter on by holding down the on/off button on the right side of the transmitter. The LED will blink every 4 seconds and the LCD screen will show the remaining battery life (the transmitter needs to be charged if there is only 1 bar showing on the battery icon for the LCD transmitter screen).
  3. Place the test light, included in the package contents, on the contact points as shown in the diagram.
  4. Watch the test light as you press the Nick button on the transmitter. It should light up for just a moment. The higher the intensity, the brighter the test light will be.
  5. Watch the test light as you press the Constant button on the transmitter. It should light up as long as the button is pressed. However, as a safety feature, the receiver will automatically stop the stimulation if the Constant button is pressed for 12 seconds or longer.
  6. Turn the Rheostat Dial on the transmitter clockwise and then counterclockwise. The test light should glow brighter with higher levels of stimulation and dimmer with lower levels.

Note: The test light may not be visible if the intensity level is set below level ten.


Proper Fit

The receiver should be fitted so that the medical grade stainless steel contact points press firmly against the dog's skin. You should be able to fit two fingers underneath the collar strap. The best location is on either side of the dog's windpipe.

Improper Fit

A loose fit can allow the receiver to move around on the dog's neck. When this happens, the contact points may rub against the skin and cause irritation. If the receiver is too loose, the contact will not be consistent and cause the corrections to be inconsistent. Dogtra uses medical grade stainless steel contact points and anti-microbial plastic to protect the dog's skin.

Attention! Leaving the receiver in the same location on the dog's neck for an extended period of time can cause skin irritation due to the sensitivity from the contact points. If the dog is to wear the receiver for long periods, occasionally reposition the receiver every few hours so that the contact points are moved to a different location on the dog's neck and remove the receiver after 8 hours of usage. Make sure you check for skin irritation each time you use the unit.


The 2300NCP EXPANDABLE has a Rheostat Dial on the top of the transmitter (0 is the lowest and 127 is the highest). Remember that you will need to adjust the setting (upward or downward) depending on your dog's temperament and threshold for stimulation. Also, as the dog's attitude changes, especially during times of increased excitement or distraction, you may need to adjust the intensity level.

Note: The stimulation intensity can be adjusted even when the stimulation is in use.


The 2300NCP EXPANDABLE has a range of ¾-mile. Depending on the way you use your transmitter, the transmitter range may vary.

To get the greatest range, hold the transmitter away from your body and avoid touching the antenna. Keep your unit properly charged for maximum signal strength.


Basic Maintenance

Make sure the rubber charging cap is securely in place when the receiver is in use. After each training session, carefully inspect the unit for any missing parts or damage to the casing. Damaged or broken casing may affect the waterproof guarantee on the unit. After confirming that there is no damage to the casing, rinse the receiver and clean out any dirt or debris.

Storage Maintenance

The unit should be fully charged before storing for extended periods. While in storage, the unit should be given a full charge once a month and before the first use. Store the units in room temperature. Do not keep the units exposed to extreme climates.


If the unit is malfunctioning, please refer to the “Troubleshooting Guide" before sending it to Dogtra for service. If you have any questions or concerns, you may email them to, or call customer service at (888) 811-9111.


  1. My dog is not reacting to the receiver.
    • Make sure the receiver and transmitter are turned on by holding down the on/off button on the transmitter and place the two red dots together to turn on the receiver until it illuminates.
    • Make sure the collar strap is tight enough so both contact points are touching the dog's skin.
    • The contact points may be too short for the dog. To place an order for longer contact points that are more appropriate for your dog, please call (888) 811-9111. If you are already using the longest contact points available, you might need to trim down the hair on the dog's neck so both contact points are touching the dog's skin.
    • The intensity level may be too low for your dog. Keep increasing the stimulation until the dog responds, usually with neck movement, head shaking, looking over its shoulder, etc. (response may be very subtle).
  2. The test light comes on, but I do not feel any stimulation.
    • Your tolerance may be higher than your dogs. We recommend placing both contact points on your inner wrist, where the sensitivity is higher, in order to test the unit.
    • The battery may be low, so check the LED light for battery life.
  3. The transmitter has no range or stimulation is less when the dog is farther away.
    • The antenna(s) may be damaged. To order parts, please contact customer service at (888) 811-9111 or go to
    • The range indicated on the unit's box is for flat terrain. Heavy brush, trees, hills, or moisture will affect the range of your unit. For best range, hold the transmitter vertically above your head, and/or try moving to higher ground.
    • Any electrical conductors will affect the range, such as cars, chain-link dog runs, metal structures, and radio towers. For best results, operate away from these items.
  4. My unit is not holding a charge.
    • The batteries might not be charged properly, or the charger, splitter, and the charging port may not be functioning properly. You can send in your charging units to have us inspect them.
    • The charging pin may be damaged. Inside the charging port, there is a metal pin that should be standing straight up and stiff. If the pin is wobbling, broken, or missing, you will need to send the unit in to the Repair Department. The charging port must be clean prior to charging; clean the dirt out with a cotton swab and some rubbing alcohol. If the dog is in salt-water, be sure to rinse the receiver and charging port with clean water.
    • If the above does not resolve your issues, contact Dogtra customer service at or (888) 811-9111.
