Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system which generally provides more immunity from false paging than
does Tone Squelch system. The DCS is built into your
VR-160
, and operation is very
similar to that just described for Tone Squelch.
Just as in Tone Squelch operation, DCS requires that you set the Tone Mode
to DCS and that you select a digital code. These actions are set up by using
the [MODE] key or Set Mode Items 51: SQL TYPE and 23: DCS CODE.
1.
Press the [
F/W
] key, then press the [
MODE
] key. This provides
a “Short-cut” to Set Mode Item 51:
SQL TYPE
.
2.
Rotate the
DIAL
knob until “
DCS
” appears on the display; this
activates the DCS Encoder/Decoder.
Note
: Do not forget to pull the
DIAL
knob to rotate the
DIAL
knob.
3.
Press the
PTT
switch to save the new setting.
4.
Press and hold in the [
BANK
] key for one second to enter the
Set mode.
5.
Rotate the
DIAL
knob to select Set Mode Item 23:
DCS CODE
.
6.
Press the [
BANK
] key briefly to enable the adjustment of the
DCS code.
7.
Rotate the
DIAL
knob to select the desired DCS Code (a three-
digit number). Ask the station owner/operator if you don’t know
the DCS Code.
8.
When you have made your selection, and hold in the [
BANK
]
key for one second to save the new settings and exit to normal
operation.
When the DCS is activated, the “
DCS
” icon will appear in the dis-
play.
During DCS operation, you may
set up the VR-160 so a ringing
“bell” sound alerts you to an in-
coming call. See page 29 for details.
