Bluetooth standby mode

When using the Bluetooth connection on the RD7100, the Bluetooth module is by default kept in standby mode. This can help to increase the locator battery life and in some applications reduce potential interference from the Bluetooth module.

The RD7100 locator provides users with the option to set the Bluetooth module to STANDBY or ON. In the ON position the Bluetooth module will be permanently ready to send data, which can help to speed up the transfer times compared to that of modules set to STANDBY mode

Troubleshooting

Successful wireless communication depends on a number of factors including: battery life, electromagnetic interference, device memory and physical obstructions.

Ensure that the RD7100 locator, and any other wireless device is sufficiently charged for wireless communication. Note that many PDAs will suspend wireless connections when their battery capacity drops below a threshold percentage. Consult your device’s documentation for more information. 

Excessive electromagnetic interference can limit the range of wireless communication and / or corrupt data. 

Your PDA device may have insufficient memory to maintain a wireless link, particularly if the connection is sustained over an hour or longer. Make sure you quit applications on your PDA using the method described in your device’s documentation.

Keep your paired device and the RD7100 locator within 10m (30ft) to maintain a wireless connection.

1. Press the key to enter the menu.
2. Scroll to the BT menu using the or keys.
3. Press thekey to enter the BT menu.
4. Scroll up or down to the RESET menu.
5. Press the key and the locator will purge all current connections.
