CTCSS/DCS/EPCS O
EPCS
The FT-1802M 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 re-
ceives 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.
Storing the CTCSS Tone Pairs for EPCS Operation
1. Press and hold in the [ MHz ( SET )] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select "
Receiving CTCSS Tone Pair or "
Transmitting CTCSS Tone Pair.
3. Press the [ MHz ( SET )] key momentarily to enable adjust-
ment 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 [ REV ( DW )] or [ LOW ( A/N )] 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 and hold in the [ MHz ( SET )] key for one second to lock in that tone/code and exit
to normal operation.
The FT-1802M does not recognize the order of the 1st tone and the 2nd tone. In
other words, for example, the FT-1802M considers both CTCSS pairs "10, 35"
and "35, 10" to be identical.
