Select any channel on either USA or INT bands. Press DUAL. The DC5s will monitor your
selected channel and channel 16 simultaneously. If a transmission is heard on either channel,
that channel will continue to be selected until no further transmission is received, then dual watch
will be re-engaged.
When using Dual Watch, the DC5s will also monitor the active WX channel for a special alert
tone issued during times of severe weather. You must select an active WX channel prior to
entering Dual Watch for this feature to work. Should this tone be received, the DC5s will emit an
alarm tone. Pressing the BAND button will switch the broadcast to the weather channel. Pressing
BAND again will exit the WX channel and you may enter Dual Watch again. You cannot enter
Dual Watch from the WX channel.
Pressing DUAL a second time will disable Dual watch.
Pressing the PTT button will also disable Dual watch. Pressing the PTT button a second time
will allow transmission.
USING SCAN
Scan is the sequential monitoring of all channels within the selected band. Pressing SCAN will
cause the DC5s to briefly monitor each channel starting with the current channel, and if no
transmission is heard, move to the next higher channel. If while monitoring a channel a
transmission is heard, the DC5s will remain on that channel until it is clear, then move to the next
channel.
Pressing the SCAN button again will disengage scan.
Pressing the PTT button will also disable scan. Pressing the PTT button a second time will allow
transmission.
