EPCS (Enhanced Paging & Code Squelch) Operation
The FTM-3100R includes an Enhanced CTCSS tone encoder/decoder and a dedicated
microprocessor providing paging and selective calling features. This allows placing a call
to a specific station (Paging), and choosing to receive calls 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 squelch will close automatically after the incoming page ends.
Storing CTCSS Tone Pairs for EPCS Operation
1. Press and hold in the [
MHz
(
SETUP
)] key for
one second to enter the Set mode.
2. Rotate the
DIAL
knob to select “
PAG CD-R
21
” for the Receiving CTCSS Tone Pair or
“
PAG CD-T 22
” for the Transmitting CTCSS
Tone Pair.

3. Press the [
MHz
(
SETUP
)] 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 [
SQL
] or [
V/M
(
MW
)] key, 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 and hold in the [
MHz
(
SETUP
)] key for one second to lock in that tone and exit to
normal operation.
Note:
The FTM-3100R does not recognize the order of the 1st tone and the 2nd tone. In
other words, for example, the FTM-3100R considers both CTCSS pairs “05, 47”
and “47, 05” to be identical.
