EPCS (Enhanced Paging & Code Squelch) Operation
The FTM-7250DR/DE 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 the [
MHz
(
SETUP
)] key to enter the
Set mode.
2. Rotate the
DIAL
knob to select “
PAG CD-R 29
” for
the Receiving CTCSS Tone Pair or “
PAG CD-T 30
”
for the Transmitting CTCSS Tone Pair.
3. Press the [
MHz
(
SETUP
)] key momentarily to en-
able 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 [
BAND
(
SQL
)] or [
V/M
(
MW
)] key, then
rotate the
DIAL
knob to set the CTCSS Tone num-
ber, which corresponds to the second tone of the
CTCSS Tone Pair.
6. Press and hold the [
MHz
(
SETUP
)] key to lock in that tone and exit to normal operation.
Note:
The FTM-7250DR/DE does not recognize the order of the 1st tone and the 2nd
tone. In other words, for example, the FTM-7250DR/DE considers both CTCSS
pairs “05, 47” and “47, 05” to be identical.
