To Stop Network Scan
Briey press the
SCAN
OS/GS
key. The animated icon will stop. As long as the
radio was not on a busy channel, it will return to the last channel you selected,
otherwise it will stay on the busy channel.
Using Priority Channels with Network Scan
If you need to use your Priority Channel (for an urgent call or an emergency),
briey press the PRI1 or PRI2 key. The Network Scan will be cancelled, and the
radio will jump straight to the selected Priority Channel. When your conversation
has nished, press the
SCAN
OS/GS
key to restore the Network Scan.
CTCSS AND DCS
CTCSS (Continuous Tone Coded Squelch System) and DCS (Digital Coded Squelch)
are similar Squelch quieting systems that allow groups of users to share the
same channel without disturbing each other. The CTCSS system uses 1 of 50 low
frequency tones to open and close the Squelch on the radio. The DCS system is
similar to CTCSS but uses 1 of 104 digital tones to control the Squelch.
Your choice of CTCSS or DCS will largely depend on which one is currently being
used by other radios in your group. If neither system is currently in use, you can
make your own choice as there is no dierence in performance between the two
systems.
NOTE: Enabling CTCSS or DCS codes do not prevent others who are not using any
codes from hearing your transmission.
CTCSS Tone Set Compatibility
The GME CTCSS tone set comprises a table of 50 tones made up of the standard
CCIR-38 Tone Set plus an additional 12 tones added to the end. If communicating
with other brands of radios that only use the CCIR-38 tone set, you should select
from one of the rst 38 tones to ensure compatibility with these models. Refer to
the CTCSS/DCS tone table in this manual for details of tone values.
IMPORTANT: If communicating with other GME radios, you can choose from any
of the 50 tones. However, please refer to the tone set tables listed in each radio’s
Instruction manual because, although the same 50 tones are available in all GME
radios, the tones used in older GME models may be listed in a dierent order.
