Obstacles that can cause an obstruction in the line-of-sight 
include trees, buildings, mountains, cars and etc.
It is NOT recommended that you leave your radio behind and 
expect your accessory to work with a high degree of reliability 
when they are separated.
At the fringe areas of reception, both voice and tone quality will 
start to sound "garbled" or "broken". To correct this problem, 
simply position the accessory and radio closer to each other 
(within the 10 meter defined range) to re-establish clear audio 
reception.
Procedure:
Note: Bluetooth tones, Bluetooth menu and preprogrammed 
buttons must be preprogrammed by a qualified radio 
technician. Check with your dealer or system 
administrator for more information.
Once a COTS headset is paired to your radio, it is 
always connected. Therefore the battery life of the 
accessory is aligned with the Talk Time power 
consumption, not the Standby Time consumption.
With your radio’s Bluetooth feature ON, and the Bluetooth tones 
enabled:
1 Turn on the accessory, then place it close to your radio 
aligning the Bluetooth Pairing Location on the radio to the 
Bluetooth Pairing Location (a blue dot) on the accessory.
2 If the pairing process is successful, you hear an 
incremental-pitched tone to indicate paired. 
OR
If the pairing process fails, you hear a short, low-pitched 
tone. The display shows Bluetooth pairing failed. Repeat 
step 1 again.
3 The radio continues to connect to the device. 
If the connecting process is successful, you hear an 
incremental-pitched tone. The display shows <Device 
Type> connected, and the Bluetooth icon turns from 
b to 
a.
OR
If the device already have pairing records and the 
connecting process fails, you hear a short, low-pitched tone. 
The display shows <Device Type> connect failed. 
Repeat step 2 to reconnect the Bluetooth device.
OR
If the connecting process immediately follows the pairing 
process and the connecting process fails to complete within 
6 seconds, you hear a decremental-pitched tone to indicate 
unpaired. The display shows <Device Type> unpaired. 
Repeat step 1 to re-initiate the pairing process.
