The VX-8R includes an Enhanced CTCSS tone encoder/decoder and a dedicated micro-
processor 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.

3. Press the key briefly to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to set the CTCSS Tone number which
corresponds to the first tone of the CTCSS Tone Pair.
5. Press the key (“¾” icon moves to the right), then ro-
tate 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-8R does not recognize the order of the 1st
tone and the 2nd tone. In other words, for example,
the VX-8R considers both CTCSS pairs “10, 35”
and “35, 10” to be identical.
