TRANSMIT TIME OUT TIMER
The Transmit Time Out Timer is a dealer programmable option that
disables the radio transmitter if a single transmission (PTT pressed continu-
ously) exceeds a preprogrammed time. When this occurs, the radio reverts to
the receive mode, even if the PTT bar is still pressed. Following the time out
period, an alert tone is sounded until the PTT bar is released and the TX LED
goes out. In this way, the Transmit Time Out Timer minimizes channel abuse.
A transmission can be initiated immediately after releasing the PTT bar by
simply pressing the PTT bar again. If the PTT bar is released prior to exceeding
the time out period, the radio operates normally (reverts to the receive mode
with no alert tone.
The time out period can be set for any period from 10 seconds to 16.5
minutes in 10 second increments.
BUSY CHANNEL LOCKOUT
The Busy Channel Lockout option prevents inadvertent transmissions on
a channel that is already being used. If this option is enabled, pressing the PTT
bar while the selected channel is in use will cause all transmit functions,
including the TX LED, to be disabled and a WARNING tone sounded.
Transmissions will be allowed only on channels that are idle (BUSY LED off).
In the Programming Mode, the user can program the scan list and two
Priority Channels, if desired. Entry into the Programming Mode is allowed
only during the first four seconds when the radio is turned on.
2. To exit the Vacant Channel Scan Mode, press the
PTT bar. The TX LED will light.
FRONT PANEL PROGRAMMING
1. To enter the Programming Mode, turn the radio
on and press and hold the "P" Priority button for
up to 4 seconds. The radio will sound the prompt
tone and display "Prog". The radio can now be
programmed with your scan list, with or without
priorities.
