ANUAL
The FTM-10SR includes an Enhanced CTCSS tone encoder/decoder and a dedicated mi-
croprocessor 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 key 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.

4. Press and hold the key for one second to display the
current Receiving CTCSS Tone Pair.
5. Rotate the DIAL knob to set the CTCSS Tone number that
corresponds to the first tone of the Receiving CTCSS Tone
Pair.
6. Press the key, then rotate the DIAL knob to set the
CTCSS Tone number that corresponds to the second tone
of the Receiving CTCSS Tone Pair.
7. Repeat step 6 for setting the Transmitting CTCSS Tone Pair.
8. If you make a mistake, press the
key to move the cur-
sor back one space, then re-select the correct number.
9. When you have made your selection of both Receiving and
Transmitting CTCSS tone pairs, press the [ VOL/SEL
] key
to save the new setting and exit to normal operation.
Note : The FTM-10SR does not recognize the order of the 1st tone and the 2nd tone. In
other words, for example, the FTM-10SR considers both CTCSS pairs “
10
,
35
”
and “
35
,
10
” to be identical.
