Replay
Replay is a facility built into the VHF which will allow a copy of the last 90 seconds of
received voice data to be replayed in the loudspeaker.
Recorded voice data will be erased at any power-down
.
Activating Replay
The front panel has a dedicated replay button.
A push on replay will bring up a window in the information/message
display. Holding down replay will drive a counter in the display by
which it is determined how many seconds of the latest received voice
data is wanted for replay.
While pressing replay in normal receive mode will still allow the VHF to receive audio in the
speaker system.
When releasing the replay button the replay function will play the last selected seconds of
data received on any channel. During replay new incoming data is not heard, nor recorded.
But incoming voice is recognized in the lower left corner of the display.
Volume control can be used on the replay data to adjust loudspeaker level.
