same input frequency) in fringe areas from locking up the repeater. There are 47 selectable CTCSS
tones provided in the FT-1500M.
To use CTCSS, both stations must be on the same frequency, and must have selected the same CTCSS
tone.
To select and activate CTCSS operation:
1. Press and hold in the [MHz] key for one second, then rotate the Main Dial knob to select
"TONE."
2. Press the [MHz] key, then rotate the Main Dial knob to select the desired squelch type from the
following:
µ "ENC"(Encode) appears when the CTCSS tone generator is activated for transmission only.
µ "ENC/DEC" (Encode/Decode) appears when the CTCSS Tone Squelch is activated for both TX
and RX (only signals "Encoded" with the matching tone will open your radio' s squelch).
3. Press and hold in the [MHz] key for one second to save the new setting and exit to normal
operation.
Now that you have selected the Tone Mode to be used, you need to select the CTCSS tone, that you
and the other station have both agreed to use:
1. Press and hold in the [MHz] key for one second, then rotate the Main Dial knob to select "TN
FRQ."
2. Press the [MHz] key, then rotate the Main Dial knob to choose the desired CTCSS tone.
3. Press and hold in the [MHz] key for one second to save the new setting and exit to normal
operation.
CTCSS settings may stored in any memory register at the time of frequency programming. To change
a memorized tone or tone system, just recall the memory channel, reset the tone or function, and store
the memory again. If you activate CTCSS on a PMS memory, it will be active when that memory pair
is used to start PMS scanning or tuning.

Tone Search Scanning

In operating situations where you don' t know the CTCSS tone being used by another station, you can
command the radio to listen to the incoming signal and scan in search of the tone being used.
Before you begin the tone search, please check the (programmable) setting of the microphone' s [P3]
button (Menu #20); it should be set to "T.SRCH" for proper operation.
To scan for the CTCSS tone in use:
1. Set the radio up for the CTCSS operation.
2. Press the [P3] button on the microphone momentarily to start scanning for the incoming CTCSS
tone.
3. When the radio detects the correct tone, it will halt on that tone, and audio will be allowed to pass.
4. Press and hold in the [D/MR] key for one second; the CTCSS tone detected will be stored as the
"current" tone, so it may be used for memory storage purposes.
It can be viewed by accessing Menu #33 (TN FRQ).
5. Press and hold in the [MHz] key for one second to exit to normal operation.

CTCSS Bell Operation

CTCSS 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 will sound to alert you to the
presence of the incoming call.
1. Press and hold in the [MHz] key for one second, then rotate the Main Dial knob to select
"BELL."
2. Press the [MHz] key, then rotate the Main Dial knob to change the display to "ON."
3. To de-activate CTCSS Bell operation, select "OFF" in step 2 above.
Calls without a matching CTCSS tone will be ignored during CTCSS Bell operation.
Note that other stations do not need to have the CTCSS Bell function to call you; they can just use
