7 SPECIAL FUNCTION KEYS
Special function keys are simply short cuts to menu screens/options. Further
information on the operation of these function keys is contained in Section 5.
This section lists Functions that may be programmed to the programmable function
keys.
Consult Simoco for those functions that have been programmed in to your radio.
7.1. ALARM
The Alarm function key is used to put the radio into Emergency Mode.
Alarm is supported in Digital mode only.
Pressing the Alarm key causes the radio to set the Emergency flag in the transmit voice
messaging and, depending on the radio configuration, optionally enter
Transmit/Receive cycle mode. In cycle mode, the radio will transmit live microphone
audio at high gain for the nominated duration and return to receive mode for the
nominated duration.
This cycle will repeat indefinitely or until the radio is turned off and on again.
7.2. ANNOUNCE
To send an Announce call on the channel, press this function key and then use the PTT
to send the call. The next PTT after the Announce will call the default group.
7.3. CHANNEL UP AND DOWN
The current selected Zone’s channel is decremented whenever the key is pressed.
The channel up and down functions are normally assigned to the ▼ /▲ function keys.
They can be assigned to other keys if required.
If the current channel is the first channel, then the decremented channel will wrap
around to the last channel in the current zone.
The new channel can be an analogue or digital channel.
If pressed and held, the function auto repeats and updates the display for every fifth
channel.
