Operating Instructions
How the Alert System Works
The Prox PRD utilizes Advanced Alert Technology, which triggers an alert when the PRD device itself is moving and separates from your paired phone. This means it will alert you if you are leaving your phone behind, rather than if your phone is moving away from you. The typical alert distance is approximately 50 to 150 feet. This range can vary based on environmental factors such as obstructions (walls, furniture) and whether you are indoors or outdoors. The device is not designed to alert at very short distances, such as 10 feet.

Button Functions
The single button on your Prox PRD device has multiple functions:

- 1 Click: Connectivity Check - Verifies the Bluetooth connection between the PRD and your phone.
- 2 Clicks: Remote Selfie Clicker - Acts as a remote shutter for your phone's camera app.
- 3 Clicks: Adjust Alert Distance - Cycles through alert distance settings (e.g., 1 beep for near, 5 beeps for far). The default alert distance is approximately 50-150 feet and cannot be adjusted to very short distances like 10 feet.
- 4 Clicks: Change Alert Tune - Cycles through available alert sounds.
- 5 Clicks + Hold: Home / Travel Mode - Toggles between modes that might adjust sensitivity or alert behavior for different environments.
- Hold Button: Nap Mode - Puts the device into a temporary sleep mode, preventing alerts for a set duration (e.g., 15m, 30m, 1hr, 2hr).

Maintenance
Battery Replacement
The Prox PRD comes with a pre-installed CR2032 lithium metal battery, which typically lasts for 1 year. When the battery is low, the device will emit a chirp every two seconds upon movement until it is turned off. The device cannot be turned back on until the battery is replaced.
To replace the battery:
- Locate the battery compartment on the back of the device.
- Carefully open the compartment using a small coin or screwdriver.
- Remove the old CR2032 battery.
- Insert a new CR2032 battery with the positive (+) side facing up.
- Close the battery compartment securely.
Cleaning
To clean your Prox PRD, gently wipe it with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners, as these can damage the device's finish or internal components.
Troubleshooting
If you encounter issues with your Prox PRD, please refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |

| Device not powering on. | Low or dead battery. | Replace the CR2032 battery. Ensure it's inserted correctly. |
| No alert when phone is left behind. | Bluetooth disconnected; device not moving; phone too close. | Ensure Bluetooth is on and paired. Confirm the PRD is moving away from the phone. Check alert distance settings (3 clicks). |
