UNIDEN XTRAK
UHF CB Transceiver
Operation
Master Scan (Uninterrupted Transmit & Receive)
Master Scan is a Transmit & Receive mode, using scan, that will allow continual comu-
nication across congested channels.
Use Master Scan with other radios that are also set up to the same Master Scan set-
tings. Master Scan will not work on its own or if its settings are different from other
radios using Master Scan.
The two settings all radios in your Master Scan network must share are;
- Scanning the same group of channels from the Group Scan (GS) memory
- Using the same CTCSS/DCS code
For your convenience, by default;
- Channels 09-20 are stored into GS Memory and
- CTCSS 01 is set as the Master Scan subcode.
By scanning only group channels, radios in the network will be able to detect and re-
ceive group transmissions - continual communication without interruption.
When transmitting in this mode, the radio switches to an unused group channel if it
detects another signal with no CTCSS/DCS code, or the wrong code, on the channel
last used by the group. In this way, all group users will be able to have continual com-
munication to or from other users.
The GS memory can be changed, channel by channel, if desired - but for Master Scan
to work effectively each radio in the group must have the same channels in its GS
memory.
To add/remove channels from G.S SCAN Memory, refer to page 23.
NOTE
RX only Channels (CH22, CH23, CH61, CH62 and CH63), Emergency
Channels (CH05, CH35), User Programmable RX Channels (CH81 to
CH180) will not be included in Master Scan Mode even though stored
into GS Memory. Also channels for which Duplex Setting is On will be
skipped in Master Scan Mode.
