Ascending tones heard. 3 Press and Hold Wireless PTT, until ascending tones heard again. 4 Release PTT. 5 Descending tones heard if unsuccessful - repeat steps 1 to 4. 739-0004/09.01 DE-AFFILIATING FROM THE WIRELESS PTT 1 Switch PRR OFF. Position Wireless PTT as for affiliation. 2 Switch PRR ON. Ascending tones heard. 3 DO NOT PRESS WIRELESS PTT. Remove Wireless PTT and return 5 times in succession within 5s of switching on radio until ascending tones heard again. 4 Descending tones heard if unsuccessful - repeat steps 1 to 3. TONES Power ON [Three short tones]. Power Off [Five medium tones]. Battery Low [Four alternating tones] Wireless PTT Affiliation/De-affiliation taking place. Repeated if successful. [Eight ascending tones]. Indicates failure of Wireless PTT Affiliation/De-affiliation. [Eight descending tones] Volume and Channel setting changes are confirmed by a single bleep in the headset, one bleep per division/setting. TO DISABLE TONES To disable the tones switch off the radio then switch on again with the PTT switch pressed. When tones have been disabled indications are recognised by interruptions in the received audio or, in the absence of traffic, as interruptions in the background noise (hiss) in short bursts equivalent in length to the related tones. OPERATION 1 Check for channel activity by listening: no audio will be heard if the channel is clear. Do not transmit if someone else is talking on the channel. 2 Press the PTT (PRR) and speak normally. 3 To receive messages, release the PTT (PRR). WARNINGS & CAUTIONS The PRR radio is an RF transmitter. Refer to separate Warnings and Cautions sheet.
