BRS (BUSINESS RADIO SERVICE) CHANNEL OPERATION
DCS Operation
Another form of tone access control is Digital Code
Squelch, or DCS. It is a newer, more advanced tone sys-
tem which generally provides more immunity from false
paging than does CTCSS Decoder. The DCS Decoder is
built into your VXA-710, and operation is very similar to
that just described for CTCSS Decoder.
Note: Just as in CTCSS Decoder, DCS Decoder requires
that you set the Tone Mode to DCS and that you select a
“Tone” Code.
Press and hold the key for 2 seconds. This instantly
recalls Menu Item (SQL Type).
Press the key again to enable adjustment of this
Menu Item.
Rotate the DIAL selector knob until “DCS” appears
on the display; this activates the DCS Decoder.
Press the key momentarily, then rotate the DIAL
selector knob two clicks clockwise to select Menu Item
(DCS Set).
Press the key again to enable adjustment of this
Menu Item.
Rotate the DIAL selector knob to select the DCS code
(a 3-digit number).
When you have made your selection, press the
key to save the new setting, then press the PTT key
repetitively until the radio exits to normal operation.
The “ ” icon will appear at the bottom of the display
when the DCS Decoder is activated.
Note: The VXA-710 will not
“remember” the DCS on/off
status and DCS Code. If you
would like to maintain the
DCS information permanently, we recommend you store
the channel information, including the DCS data, into a
Memory Channel. See page 20 for details regarding
Memory storage.
