Setup
Battery Installation
The Bc26a device requires one (1) 9V Alkaline battery (not included) for operation.
- Locate the battery compartment cover on the back of the device.
- Slide or unclip the cover to open the compartment.
- Insert a new 9V Alkaline battery, ensuring the positive (+) and negative (-) terminals align correctly with the markings inside the compartment.
- Close the battery compartment cover securely until it clicks into place.
Important: Always use a fresh 9V Alkaline battery for optimal performance. Remove the battery if the device will not be used for an extended period to prevent leakage.
Operation
Using the Bark Stop Function (Ultrasonic)
The ultrasonic bark stop function emits a high-frequency sound that is typically audible only to dogs and cats, designed to distract and deter unwanted barking.
- Point the front of the device directly towards the barking animal. The effective range is up to 50 feet.
- Press and hold the designated ultrasonic button (refer to device markings for specific button).
- Release the button once the animal stops barking or is distracted.
- Use consistent training methods in conjunction with the device for best results.
Note: Humans cannot hear the ultrasonic sound. The absence of audible feedback does not mean the device is not working.
Using the Personal Siren
The personal siren emits a high-decibel alarm for personal protection or to attract attention in emergencies.
- Locate the pull tab siren mechanism on the device.
- Pull the tab firmly to activate the high-decibel siren.
- To deactivate the siren, reinsert the pull tab securely into its slot.
Using the Flashlight
The integrated LED flashlight provides illumination in low-light conditions.
- Press the designated flashlight button (refer to device markings).
- Press the button again to turn off the flashlight.
Maintenance
Cleaning
- Wipe the device with a soft, dry cloth.
- Do not use abrasive cleaners or solvents.
- Caution: This device is not water resistant. Do not expose it to water or excessive moisture.
Battery Replacement and Storage
- Replace the 9V battery when the device's functions (ultrasonic, siren, flashlight) become weak or cease to operate.
- If storing the device for an extended period, remove the battery to prevent potential leakage and damage to the unit.
- Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on or functions are weak. | Low or dead battery; incorrectly installed battery. | Replace with a fresh 9V Alkaline battery. Ensure battery is installed with correct polarity. |
| Ultrasonic bark stop is ineffective. | Animal is out of range; animal is not receptive to ultrasonic sound; inconsistent use. | Ensure device is pointed directly at the animal within 50 feet. Some animals may not respond. Use consistently as part of a training regimen. |
| Siren does not stop after pull tab is reinserted. | Pull tab not fully reinserted; internal malfunction. | Ensure the pull tab is pushed completely into its slot. If the issue persists, remove and reinsert the battery. If still unresolved, contact customer support. |
| Device drains batteries quickly. | Device may be partially active when off; faulty unit. | Ensure all buttons are fully released when not in use. Remove battery if storing for extended periods. If problem continues, contact customer support. |
| Buttons are difficult to press individually. | Design characteristic; user technique. | Exercise care when pressing buttons to ensure only the desired function is activated. |
