Useful functions
•Program Scan
This is a type of VFO scan, which is done by setting the fre-
quency range of the VFO into the PH and PL channels, it only
scans between those frequencies. When the PH and PL are
set properly, up to 3 Program scan ranges will be available,
which are L-PH, PL-PH and PH-H.
1.Enter the VFO mode and set the PL and PH
frequencies into the designated memory chan-
nels. Refer to Memory setting for the proper
sequence.
2.Return to the VFO mode by pressing V/M key.
Set the VFO to...

•DCS scan
Same as previous, but for DCS code search.
1.While in the DCS setting, press the UP/DOWN
key for more than 1 second but less than 2 sec-
onds to start scanning.
(It scans 105 DCS codes in order.)
• During scanning, the 1 MHz order decimal
point will flash.
• The scan stops when the matching DCS code
is detected and reception starts.
2.When scanning has finished, pressing any key
other than the UP/DOWN key will cancel the
scan mode.

1.Press the TS/DCS key while the FUNC key is
pressed.
[AM] icon illuminates on the display to show
the unit is in the AM reception mode.
2.Repeat the same operation to return to the FM
mode.
When the AM RX mode is set, the FM mode
will be used for TX even though the AM icon
remains displayed.
1.Press the MHz key together with the FUNC key.

Many repeaters require a CTCSS tone or a DCS encode setting as a “key” to access a repeater
system, or a receiver using CTCSS or DCS squelch, so-called “selective-calling”. Sometimes,
CTCSS or DCS decode features are used on the output of a repeater so they can be used to open a
squelch. In this mode, regardless of the main squelch status, the audio can be heard ONLY when
the matching tone/code signal is received. The combination of CTCSS squelch and DCS function
is not available; only one or the other...
