FTM-10R Operating Manual

receives a call from another radio sending out a matching CTCSS tone. This can

help keep your radio quiet until a specific call is received, which may be helpful

while operating in congested areas.

Notes: 1) You may notice a “REV TONE” indication on the display while you rotate

the DIAL knob in this step; this means that the Reverse Tone Squelch system is

active, which mutes your FTM-10R’s receiver (instead of opening the squelch) when

it receives a call from the radio sending a matched CTCSS tone. The “T SQ” icon

will blink on the display when the Reverse Tone Squelch system is activated.

2) You may notice a “DCS” indication on the display while you rotate the DIAL knob

still more. We’ll discuss the Digital Code Squelch system shortly.

5. When you have made your selection of the CTCSS tone mode, press the [X] key

momentarily, then rotate the DIAL knob three clicks counter-clockwise to select

Menu Item “F35 SQL.TSQLF.” This Menu selection allows setting of the CTCSS

tone frequency to be used.

6. Press the [X] key to enable adjustment of the CTCSS frequency.

7. Rotate the DIAL knob until the display indicates the Tone Frequency you need to be

using.

8. Press the [SELECT] key momentarily to save the new setting and exit to normal

operation.

Note: Your repeater may or may not re-transmit a CTCSS tone - some systems just use

CTCSS to control access to the repeater, but don’t pass it along when transmitting. If

the S-Meter deflects, but the FTM-10R is not passing audio, repeat steps “1” through “4”

above, but rotate the DIAL knob so that “TONE” appears - this will allow you to hear all

traffic on the channel being received.

DCS Operation

Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more

advanced tone system which generally provides more immunity from false paging than

does CTCSS. The DCS Encoder/Decoder is built into your FTM-10R, and operation is

very similar to that just described for CTCSS. Your repeater system may be configured

for DCS; if not, it is frequently quite useful in Simplex operation if your friend(s) use

transceivers equipped with this advanced feature.

Note: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and

that you select a Tone Code.

1. Press and hold the [SELECT] key for one second to activate the Menu (SET) mode.

2. Rotate the DIAL knob to select Menu Item “F38 SQL TYPE.”
