Exact model and revision matter: do not assume pairing steps, batteries, or receiver parts are interchangeable. For suspected stimulation failure, use the supplied test light as directed by the manual rather than guessing from your dog’s response.
Before troubleshooting: identify the model and generation
Identify the transmitter and receiver models before applying a procedure or buying a part. Consult the matching ET-300/302 manual; procedures and compatibility can differ for older TS systems and individual receiver models. Keep the model and component serial numbers available for manufacturer support.
The safe troubleshooting sequence
- Remove the receiver from your dog. Troubleshoot and test output off the dog.
- Charge the transmitter and receiver using the appropriate charging equipment and check their indicator lights.
- Confirm the transmitter display is on and the receiver shows its expected charge and operating status.
- Check response and pairing: press the relevant control and observe the receiver light; use the official instructions to pair or sync if needed.
- For suspected output problems, use the supplied test light following the owner manual.
- Check fit and contact points for the correct receiver and your dog’s coat; stop if skin irritation appears.
- If range is reduced, charge the transmitter and use the manual’s recommended grip, keeping fingers off the antenna.
- Contact E-Collar Technologies if the problem persists or the device is damaged.
Do not do these things
- Do not repeatedly raise stimulation to diagnose a fault.
- Do not test a malfunctioning collar on your dog.
- Do not use a charger, battery, or receiver part based only on a matching connector or appearance.
- Do not open or modify the device to bypass its controls.
- Do not keep the receiver on irritated, broken, or sore skin.
Indicator lights and charge checks
| Indicator behavior | Manufacturer guidance | What to do |
|---|---|---|
| Receiver light turns green when connected to its charger | The 300/302 manual describes this as the receiver charging indication. | Confirm the charger and connection are appropriate for your model. |
| Blinking green | The manufacturer FAQ describes this as fully charged. | Continue with the power and response checks. |
| Yellow or orange | The FAQ says the battery is approaching a low level. | Charge the unit. |
| Blinking red while idle | The FAQ says limited usage time remains. | Charge promptly. |
| Red during a transmitter button press | The FAQ says this indicates the receiver is receiving the signal. | If the receiver does not respond, check pairing and the model-specific manual. |
Indicator behavior can vary by model. Consult the matching manual if your unit’s lights differ from these descriptions.
If the transmitter or receiver will not turn on
- Charge the receiver and check whether its light turns green when connected, as described in the 300/302 manual.
- Check the transmitter display. The manual’s receiver-response checks assume the transmitter LCD is on.
- Check the charging connection and use only equipment appropriate for the exact model and revision.
- If the unit remains unresponsive, stop troubleshooting and contact support. Do not open the housing or substitute an unverified charger or battery.
The manufacturer FAQ describes a typical charge hold of 24–48 hours for the remote and receiver; actual runtime can vary. The FAQ also gives a general Li-Po lifespan of about 1–2 years or 200–300 charge cycles before performance loss, not a guarantee for every battery. If runtime drops substantially, identify the exact component before considering a replacement.

If the receiver does not respond to the transmitter
- Confirm the transmitter LCD is on and the receiver is charged and powered.
- Press the relevant transmitter control and watch the receiver indicator.
- If the receiver light turns red, it is receiving the signal, according to the manufacturer FAQ.
- If it does not respond as expected, verify that the transmitter and receiver are paired or synced using the official instructions for your system.
- If pairing and charge checks do not resolve the problem, contact manufacturer support.
Do not rely on pairing steps from a different generation. The manufacturer advises confirming that the transmitter and receiver are properly programmed together when the receiver collar light does not turn red.
If the receiver seems not to provide stimulation
Do not infer an output failure from your dog’s response. Remove the receiver from the dog and test it only as the owner manual directs.
- Confirm both components are charged and powered on.
- Remove the contact points as directed by the manual and connect the supplied test light to the receiver.
- Activate the device according to the manual’s test procedure.
- A blinking test light indicates that the receiver is providing stimulation.
- If the prescribed test fails, stop and contact manufacturer support rather than testing on your dog.
If you cannot change the stimulation level
Check the display for the level-lock icon. The 300/302 manual says a solid 1D or 2D means adjustment is locked; a blinking 1D or 2D means the level can be adjusted. Press the stimulation knob for one second to unlock adjustment, as described in the manual for the applicable model.

The 300/302 manual identifies a low transmitter battery as a possible cause of reduced range and instructs users to keep fingers off the antenna and follow its recommended holding technique.
- Charge the transmitter.
- Hold it as described in the matching manual, keeping fingers away from the antenna.

The manufacturer FAQ says traditional contact points contain nickel and some dogs may be sensitive. If redness, irritation, hair loss, or sores appear, remove the receiver and discontinue use until symptoms subside. The FAQ suggests considering hypoallergenic points or a comfort pad after symptoms resolve; these products are not a diagnosis or a reason to continue wearing the collar over irritated skin. Ask a veterinarian about persistent skin problems.
Replacement parts and support
Identify the exact transmitter and receiver model before ordering parts. The manufacturer’s battery listing describes a 400 mAh Li-Po battery compatible with ET-300/302 transmitters and excludes older TS models. It gives different receiver details, including an RX-090 3.7V 300 mAh battery; do not apply the transmitter battery recommendation to every receiver.
The manufacturer lists an ET-300/302 replacement handheld transmitter. It does not include a wall charger, lanyard, or belt clip. Treat replacement hardware as an escalation after basic checks and confirm compatibility and accessory needs with the manufacturer.
