The
VX-6E
includes an Enhanced CTCSS tone encoder/decoder and a dedicated micro-
processor providing paging and selective calling feature. 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 which is
stored in the Transmitting Pager Memory will be transmitted automatically.
On the paged radio, the 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-acti-
vate the Enhanced Paging and Code Squelch system again using Set Mode Item 43:

Storing the CTCSS Tone Pairs for EPCS Operation
1. Press the [

)] key to enter the Set mode.
2. Rotate the
DIAL
knob to select Set Mode Item 45:

3. Press the [
0
(
SET
)] key momentarily 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 [
MODE
(
SP S
)
SQ TYP
] key, then 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.
T h e V X - 6 E
does not recog-
nize the order of
the 1st tone and the 2nd
tone. In other words, for
example, the VX-6E con-
siders both CTCSS pairs
“10, 35” and “35, 10” to
be identical.
