OPERATION
The transceiver can operate in VFO, MR or Channel mode. VFO allows you to directly enter in the frequency you wish to use via the keypad. In channel
mode, up to 99 pre-programmed channels can be selected, only the channel number is displayed. In MR mode, both the channel number and frequency
are displayed. To switch between VFO and Channel modes, turn the transceiver off, hold down
F
and turn the transceiver on. If CH-xx (where xx is a
number between 01 & 99) is displayed, it is in channel mode, otherwise it is in frequency mode. MR mode is selected by first entering VFO mode and
then pressing
VFO
. If at least one channel has been programmed, the channel number will be displayed to the left of the frequency. Various operating
parameters can be set in various modes as per the following table.

Adding a channel
•
In VFO mode, set up the desired frequency you wish to store
including any CTCSS/DCS tone or code & frequency offset.
•

CTCSS & DCS
This transceiver is compatible with systems using Continuous Tone Control Squelch (CTCSS) and Digital Coded Squelch (DCS) systems. You can code
each frequency with a specific CTCSS or DCS tone. When enabled and your transceiver receives multiple signals, you will only hear the transmission
with the correct CTCSS or DCS tone you have programmed. If you do not receive the correct tone with the signal, the transceivers squelch remains
"closed" and you hear nothing. The systems are also used with some radio repeater systems.
CTCSS (Continuous Tone Coded Squelch System)
Also known by a number of different trade names such as Private
Line® (PL) by Motorola, Channel Guard® (CG) by General Electric
and generically as Tone Squelch. The system uses sub-audible tones
that are transmitted along with the speech portion of the transmission
to allows more than one agency (or fleet) to use the same radio
frequency without causing undue interference to another agency on
the same frequency. Receivers for agency “A” are set to only open
their audio squelch when the proper sub-audible frequency tone is part
of the transmission.
DCS (Digital Code Squelch
)
This is similar to CTCSS but uses a slow speed binary data stream
passed as sub-audible data along with the transmission. Motorola calls
this Digital Private Line® (DPL).
