Tone Search Scanning
In operating situations where you don’t know the CTCSS or DCS code being used by
another station or stations, you can command the radio to listen to the incoming signal and
scan in search of the tone being used.
To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous discus-
sion). In the case of CTCSS, “
ENC
/
DEC
” will appear on the display; in the case of DCS,
“
DCS
” will appear on the display.
2. Press and hold the [ BAND
] key for 1/2 second, then rotate the
Main Dial knob to select
Menu # 30 (
TSRCH
) for CTCSS tone search or Menu # 9 (
DCS S
) for DCS code search.
3. Press the [ BAND
] key to start scanning for the incoming CTCSS or DCS tone/code.
4. When the radio detects the correct tone or code, it will halt on that tone/code, and audio
will be allowed to pass. Press the [
BAND
] key to lock in that tone/code and exit to normal
operation.
CTCSS Bell Paging
Bell Paging adds an alert ringer to CTCSS tone squelch operation, for added convenience.
When you receive a call with a matching CTCSS tone, the ringer sounds to alert you to the
presence of the incoming call.
To activate CTCSS Bell operation, press the [
TONE
] key until “
” appears on the display..
As before, calls without a matching CTCSS tone will be ignored. Those with a matching tone
will cause the transceiver to ring as the squelch opens while
the caller transmits. Note that other stations do not need to
have the CTCSS
Bell function to call you; they can just use
standard CTCSS encoding.
When you reply to a CTCSS Bell call, you may want to turn off the Bell function, or else the
transceiver will ring every time your squelch opens.
You can store CTCSS Bell Paging as a “tone mode” in a memory, as you can do with different
CTCSS/DCS tone and encode/decode status.
1750 Hz Tone Calling (European Versions)
In the European versions of the FT-7100M , press the [ P1
] (
MH-48
A6J
) or [ ACC
] (
MH-
42
B6JS
) button on the microphone to transmit a 1750 Hz Burst Tone for repeater access.
If you own a non-European version of the FT-7100M , but plan on visiting a country which
requires a 1750 tone for repeater access, you may use menu #20 to set up the [ P1
] (
MH-
48
A6J
) or [
ACC
] (
MH-42
B6JS
) button for 1750 Hz Tone operation. See page 43 for details.
