Revert Mode The Revert Mode refers to whether the radio will, when keyed, transmit on the
currently selected memory channel, or on the last contacted memory channel. The radio will only
respond on the last contacted channel for a time determined by the Delay Timer setting, once the
Timer times out, the unit then always transmits on the selected channel.
Default: last contacted
Reply Timer The scan Reply time is the time that the radio will monitor a channel on which RF
was received, after all activity on the channel has ended (Rx or Tx). If there is further receive or
transmit activity on the channel, the timer will reset, and start again once the activity has ended.
When the timer times-out the unit will resume scan. If set to zero (0), the unit will resume scan
immediately upon the end of channel activity.
Range: 0-20s, Default: 3 seconds
Monitor Timer This is the time that the radio will monitor a channel on which RF was received,
before resuming scanning. Once the timer expires, the unit will break and resume scan, if the
value is set to zero (0) then the unit will monitor the signal as long as it is received.
Range: 1-90s, Default: 10 seconds
Delay Timer The Delay time is the time that the radio will remain monitoring a channel after
receiving on that channel has ended. If the timer is set to zero, (0), then the unit will resume
scanning immediately after receive activity has ended. This is the timer that affects the Revert
Mode 'Contacted'.
Range: 0-15s, Default: 5 seconds
Mixed Mode Operation (L2-7)
The radio supports a mode of operation that allows mixing of analog and digital operating modes.
In effect, this mode allows one memory position to be set up as though it has up to 8 sets of
parameters associated with it. This mode is also referred to as 'multi-mode' or 'shadow channel'
operation.
The user invokes this mode by creating a 'shadow' memory (using command L2-7) and assigning
it to an existing memory (known as the 'primary').
Any 'primary' can have up to seven (7) 'shadows' for a total of eight (8) sets of operating
parameters (1 primary + 7 shadows). Each 'shadow' takes up one memory position, just like a
normal memory.
The shadows have certain restrictions:
• a shadow must have the same frequency as the primary
• a shadow cannot have scan enabled
• a shadow cannot transmit in digital ID call (i) mode
You can mix analog and digital Operating Modes, you can configure different shadows to have
different squelch parameters.
Shadow operation is much like scan in last contacted mode, once a signal has been received, the
user has a set amount of time to key the radio, the unit will transmit with the parameters of the
shadow that decoded the signal: in other words you will respond to the person who called you.
