Should the radio be turned off (battery change) while the Bluetooth module is on,
you hear in the communication set for 30 seconds an acoustic warning signal in
two (2) second intervals. During these 30 seconds press a key or turn the radio on,
to ensure the Bluetooth module continues in switched-on condition. This way it is
possible to keep up telephone standby.
Switch off the Bluetooth module
Turning the radio off, switches the Bluetooth module off as well, with a delay of 30 seconds. However,
you are also able to disconnect the entire system, independently from the radio.
Press simultaneously both, the Bluetooth and Volume-up keys, for about 3 seconds until you hear a
descending
three-tone sequence in the communication set which confirms the switch-off. The LED
in the Bluetooth key does not glow anymore. Let the keys go.
7.19 End of operation
To end the operation, turn the radio off.
In some radios, the accessory interface continues energized, even after turning the
radio off. In such a case switch the key off manually, or disconnect the CTMultiPTT
Bluetooth plug from the radio adapter. Otherwise, it is possible that the CT-
MultiPTT Bluetooth storage battery is discharging.
