similar to that just described for CTCSS. Your repeater system may be configured for
DCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use
transceivers equipped with this advanced feature.
R.F. Says: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS
and that you select a tone code.

5.
Press the [H/L] key momentarily to enable the adjustment of the DCS code.
6.
Rotate the DIAL knob to select the desired DCS Code (a three-digit number). Ask
the repeater owner/operator if you don't know DCS Code; if you are working
simplex, just set up the DCS Code to be the same as that used by your friend(s).
7.
When you have made your selection, press the [H/L] key momentarily,, then press
the PTT switch to save the new settings and exit to normal operation.
R.F. Says: Remember that the DCS is an Encode/Decode system, so your receiver will
remain muted until a matching DCS code is received on an incoming transmission.
Switch the DCS off when you're just tuning around the band!
Tone Search Scanning
In operating situations where you don't know the CTCSS or DCS tone being used by
another station or stations, you can command the radio to listen to the incoming signal
and scan in search of the tone being used. Two things must be remembered in this
regard:
You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
Some repeaters do not pass the CTCSS tone; you may have to listen to the station(s)
transmitting on the repeater uplink (input) frequency in order to allow Tone Search
Scanning to work.
To scan for the tone in use:
1.
Set the radio up for either CTCSS or DCS Decoder operation (see the previous
discussion). In the case of CTCSS, "TSQ" will appear on the display; in the case of
