1. Introduction
The Black Diamond Guide BT Beacon is a professional-grade avalanche rescue transceiver designed for precise location and faster victim detection in backcountry environments. It features both digital and analog search modes, Bluetooth connectivity for app integration, a 60-meter circular range, and an automatic antenna switch to optimize signal transmission. This manual provides essential information for the proper setup, operation, and maintenance of your Guide BT Beacon.
2. Setup
2.1 Battery Installation
The Guide BT Beacon operates on standard AAA batteries. To install or replace batteries, locate the battery compartment on the back of the device. Open the compartment, insert the batteries according to the polarity indicators, and securely close the cover. Always use fresh, high-quality alkaline batteries for optimal performance and reliability.
2.2 Wearing the Harness
The beacon comes with a harness-style carrying pouch for secure and accessible wear. Place the harness over your left shoulder, ensuring the beacon pouch rests comfortably on your chest. Secure the waist strap around your back and clip it in front. Adjust the straps for a snug fit that allows for quick access to the beacon. The beacon should be worn under your outer layers to protect it from impact and weather.

3. Operating Modes
The Guide BT Beacon features a simple three-position switch for Off, Send, and Search modes, along with a locking mechanism to prevent accidental mode changes.
3.1 Power On/Off and Lock
- To unlock the switch, slide the green lock mechanism away from the main switch.
- To power on, slide the main switch to the 'SEND' position. The device will perform a self-check.
- To power off, slide the main switch to the 'OFF' position.
- Always engage the lock mechanism after selecting a mode to prevent unintended changes.
3.2 Send Mode
In 'SEND' mode, the beacon continuously transmits a signal, making you detectable by other avalanche transceivers. This is the default mode for all backcountry travel. The display will show an 'OK' or similar indicator to confirm signal transmission.
3.3 Search Mode
In 'SEARCH' mode, the beacon receives signals from other transceivers. The display provides visual cues (arrows for direction, numerical distance) and audible tones to guide you to a buried victim. The device can also indicate multiple burial scenarios, allowing for efficient marking and scanning.

4.2 Integrated Inclinometer
An integrated inclinometer allows for quick and accurate assessment of slope angles, a critical factor in avalanche risk evaluation. This feature aids in making informed decisions in the backcountry.
4.3 Automatic Antenna Switch
The automatic antenna switch intelligently selects the antenna that provides the strongest signal, ensuring optimal transmission and reception. This feature enhances the beacon's reliability in various conditions.
5. Maintenance
- Battery Check: Regularly check battery levels, especially before each outing. Replace batteries when they reach 20% or less.
- Cleaning: Clean the beacon with a soft, damp cloth. Avoid abrasive cleaners or solvents. Ensure the device is dry before storage.
- Storage: Store the beacon in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
- Software Updates: Periodically check for and install firmware updates via the PIEPS App to ensure your beacon has the latest features and performance enhancements.
6. Troubleshooting
If you encounter issues with your Black Diamond Guide BT Beacon, consider the following:
- No Power/Display Issues: Check battery installation and charge level. Replace batteries if necessary.
- Signal Interference: Ensure no other electronic devices (mobile phones, cameras, GPS units) are too close to the beacon, as they can cause interference. Maintain a minimum distance of 20 cm (8 inches) in send mode and 50 cm (20 inches) in search mode.
- App Connectivity Issues: Ensure Bluetooth is enabled on your smartphone and the beacon. Restart both devices and try pairing again.
- Unusual Behavior: Perform a self-check using the PIEPS App. If issues persist, contact Black Diamond customer support.
