Alert Tone Indicators

Power-Up

Each time the radio is turned on, a microcomputer and syn- thesizer self-test occurs. A high pitched alert tone is gener- ated for approximately 1/8 second to indicate that the microcomputer and synthesizer are functioning properly. A second low pitched tone is generated if the start-up test is not successful.

Transmit on Blank or Receive-

Only Channels

Pressing the PTT button while tuned to a blank or “receive- only” channel causes an alert tone. The tone continues as long as the PTT button is depressed. The radio transmit- ter is not enabled.

Transmit Inhibition Busy Channel with Busy Channel Lockout

Pressing the PTT button during a “busy channel” condition (other than your PL/DPL group) generates a continuous busy tone that lasts as long as the button is depressed.

Time-Out Timer

The time-out timer limits the amount of transmission time to a preset length (off, 30 or 60 seconds). At the end of this time an alert tone indi- cates that your transmission has been cut off. The alert will continue as long as the PTT switch is depressed.
