The
VX-8GR/GE
includes an Enhanced CTCSS tone encoder/decoder and a dedicated
microprocessor providing paging and selective calling features. This allows you to place
a call to a specific station (Paging), and to receive calls of your choice directed only to you
(Code Squelch).
The paging and code squelch systems use two pairs of (alternately switched) CTCSS
tones which are stored in the pager memories. Basically, your receiver remains silent until
it receives the CTCSS tone pair that matches those stored in the Receiving Pager Memory.
The squelch then opens so the caller is heard, and the paging ringer immediately sounds,
if activated. When you close the
PTT
switch to transmit, the CTCSS tone pair that is
stored in the Transmitting Pager Memory will be transmitted automatically.
On the paged radio, the Code Squelch will close automatically after the incoming page
ends. Meanwhile, on the paging radio, the Enhanced Paging and Code Squelch system
will be disabled after the
PTT
switch is released after the paging transmission. You may
re-activate the Enhanced Paging and Code Squelch system again.

4.
Rotate the

corresponds to the first tone of the CTCSS Tone Pair.
5.
Press the

rotate the
DIAL
knob to set the CTCSS Tone number, which
corresponds to the second tone of the CTCSS Tone Pair.
6.
Press the
PTT
switch to save the new setting and exit to
normal operation.
The
VX-8GR/GE
does not recognize the order of
the 1st tone and the 2nd tone. In other words, for
example, the
VX-8GR/GE
considers both CTCSS
pairs “10, 35” and “35, 10” to be identical.
