- Ensure both devices are off.
- Turn on the remote transmitter by holding the 'L' button for 2 seconds.

3. Fitting the Collar
Proper collar fit is crucial for effective and humane training.
- The collar should be placed on the side of the dog's neck, not directly under the throat.
- Ensure the contact points make direct contact with the skin. You may need to part thick fur.
- The fit should be snug enough that two fingers can barely fit between the strap and the dog's skin. It should not shift around.
- The strap is adjustable from 6 to 30 inches and can be trimmed to size.

Operating Instructions
Stimulation Levels and Modes
The ET-300 offers 100 levels of stimulation, adjustable via the dial on the remote.
- Stimulation Level Dial: Rotate clockwise to increase and counter-clockwise to decrease the stimulation level (0-100).
- Safety Lock: To lock a specific stimulation level, hold the dial down for 5 seconds. This prevents accidental changes.
- Momentary (Black 'S' button): Delivers a single, brief stimulation.
- Continuous (Red 'S' button): Delivers continuous stimulation for as long as the button is held, up to 10 seconds.
- Vibration or Tone (Black 'T' button): Toggles between a tapping sensation (vibration) and a tone. Press the 'T' button to activate.
- Stimulation Boost: The red 'S' button can also deliver a boosted stimulation (1-60 levels above the set level). Default boost is 5.
Range and Visibility
- 1/2 Mile Signal Range: Ideal for open spaces, hunting, or field training. Note that range may vary due to terrain, weather, foliage, and other radio transmissions.
- Light and On/Off Button (Black 'L' button): Press to activate the LED light on the collar for night tracking or increased visibility.
