26 FT-2900R OPERATING MANUAL

TONE SEARCH SCANNING

In operating situations where you don’t know the CTCSS tone 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. Two things must be remembered in this regard:

 You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).

 Some repeaters do not pass the CTCSS tone or DCS code; you may have to listen to the

station(s) transmitting on the repeater uplink (input) frequency in order to allow Tone

Search Scanning to work.

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, “

TSQTSQ

TSQ” will appear on the display; in the case of DCS,

“

DCSDCS

DCS” will appear on the display.

2. Press the Microphone’s

[

]

key momentarily to start scan-

ning for the incoming CTCSS or DCS tone/code.

3. When the radio detects the correct tone or code, it will halt

on that tone/code, and audio will be allowed to pass.

4. Press the Microphone’s

[

]

key momentarily to lock in

that tone/code and exit to normal operation.

If the Tone Scan feature does not detect a tone or code, it will continue to scan

indefinitely. When this happens, it may be that the other station is not sending any

tone. You can press the Microphone’s

[

]

key to halt the scan at any time.

You may listen to the (muted) signals from the other stations during Tone Scanning when
