RECEIVING A SIGNAL ON A GROUP SCAN CHANNEL
If a signal is received on a programmed scan channel, the radio will ‘lock* onto that channel
provided there is no signai on the PRiORITY channei.
When the receiver is ‘locked’ onto the scan channel, and at the same time, the channel dis­
play will flash from the scan channel to the PRIORITY channel. This is because the receiv­
er is still ‘listening’ for signals on the PRIORITY channel.
When the scan channel becomes quiet again, the radio will continue to hold the channel for
a further 3 seconds in order to allow for a natural pause in the conversation before resum­
ing the Group Scanning mode.
If there is a transmission on the PRIORITY channel while you are listening to a scan chan­
nel. the receiver will immediately transfer to the PRIORITY channel and the PRIORITY
channel number will be displayed.
To manually HOLD a scan channel indefinitely, momentarily press the MEM switch. The
radio will cease scanning and will hold the channel, but will continue to DUAL WATCH the
PRIORITY channel. The S go on and off on the CHANNEL indicator.
To RESUME scanning, momentarily press the MEM switch again. The receiver will re­
sume scanning.
To transmit on a Group Scan channel, rotate the channel switch to the required channel,
making it the PRIORITY channel. Return the channel selector to the correct PRIORITY
channel when you have completed your conversation.
REMOVING OPEN SCAN CHANNELS
When the radio is initially powered upfrom the box, all 40 channels will be programmed into
the OPEN SCAN MEMORY.
If you do not wish to scan any particular channels (e.g. if one or more channels are continu­
ally busy and always causing the scanning function to pause), you may remove these
channels from the scan group using the following sequence.
1. Select the NORMAL mode by pressing the SCAN switch.
The S should not be indicated on the CHANNEL indicator.
2. Select the OPEN SCAN mode by pressing the GROUP switch. The G should NOT be
indicated on the CHANNEL indicator.
3. Rotate the CHANNEL SELECTOR switch until the channel you wish to REMOVE is
displayed on the CHANNEL indicator.
Note that ME is indicated on the CHANNEL indicator, showing you that this channel is
currently included in the scan group.
4. PRESS and HOLD the MEM switch for about 2 seconds until a BEEP is heard twice.
NOTE: that the ME is now extinguished.
