Option Button Functions
The following functions may be applicable to your radio, activated by one of the function/option buttons.
■Call Buttons - When a Call button (Base Call / Variable Call) is pressed, a specified sequence of tones is transmitted to set up your call.
■Repeater Talkaround 
- This feature enables the transmit frequency on a channel to be switched to the same as the channel’s receive frequency. This will allow a radio to communicate directly with another without the need to use a repeater.
■Call Forward 
- This feature allows you to pass on calls automatically to another radio, which may be your portable radio when you are away from your vehicle.
■Monitor 
- One option button (usually 5) may be programmed as Monitor. This feature allows the user to switch between different receiver settings programmed as Receive, Monitor 1 and Monitor 2.
■Scan 
- The scan feature will cause the radio to search through predefined lists of channels looking for a condition that will cause the radio to unmute. While searching for unmute conditions, the radio is in ‘active scan’ (green LED flashing and Scan icon on - display models only); having
found the required conditions, the radio will ‘land’ on the channel ( display models - green LED off, Scan icon stays on ;
■Nuisance Channel Delete - When in scan, if the radio repeatedly ‘lands’(stops) on a channel that is currently of no interest, press this option button when listening to the ‘nuisance channel’, to temporarily remove the channel from the scan list (until the radio is turned off then on again).
■External Alarm enable/disable 
- Turns the external alarm signal, generated by selective call decode, on/off.
■Memory Channel (display models only) - Up to two option buttons may be programmed as Memory Channels. To select the channel, press the option button for a period of less than one second. Optionally, pressing the button for longer than one second selects the current channel as that button’s memory channel.
■Voice Scrambler 
- When the radio is fitted with an optional speech scrambler module, two further features may be programmed onto the option buttons.
– Coded/Clear speech - the scrambler module may be switched on and off to suit operational requirements.
