Mic Gain Setting; Split Tone Operation; Dtmf Operation - Yaesu FTM-7250DR Operating Manual

Miscellaneous Settings
TX Deviation Level
You can reduce the receiver bandwidth and transmit deviation when operating on closely
spaced frequencies (channel spacing of 12.5 or 15 kHz). The reduced transmitter devia-
tion will minimize adjacent channel interference to other users.
Note: See Setup Menu Item "W/N DEV 55* (53)" on 41. (*: USA version)
Displaying the Supply Voltage
Display the Power Supply voltage.
Note: See Setup Menu Item "DC VOLT 9" on 39.

MIC Gain Setting

At the factory, the microphone gain has been programmed so that it should be satisfac-
tory for the supplied MH-48A6JA Microphone. If you use an after-market microphone or
connect a TNC, you may wish to set a different Mic Gain level.
Note: See Setup Menu Item "MIC GAIN 25" on 40.
Displaying the Temperature
Indicates the current final transistor & heatsink temperature.
A temperature below 25°C (77°F) will be indicated as 25°C (77°F).
Note: See Setup Menu Item "TEMP 46" on 41.
Band Edge Beeper
The FTM-7250DR will automatically "beep" when the receiver's band edge is encoun-
tered during scanning (either in standard VFO scanning or during PMS operation). You
may additionally enable this feature (band edge beeper) when the frequency reaches the
band edge while selecting the VFO frequency manually, using the DIAL knob.
Note: For details, refer to the Advanced Manual (download from the Yaesu website).

Split Tone Operation

The FTM-7250DR can be operated in a "Split Tone" configuration that enables operation
on repeaters using a mix of both CTCSS and DCS control via the Setup menu.
Note: For details, refer to the Advanced Manual (download from the Yaesu website).

DTMF Operation

DTMF tones (Dual Tone Multi Frequencies) are the tones you hear when dialing from a
telephone keypad. The FTM-7250DR transceiver can transmit the DTMF codes by using
the keys on the microphone or recalling registered number strings from memories.
The maximum of 16-digit DTMF codes can be registered in up to 10 memory channels.
It is convenient to register telephone patch numbers, and network linking sequences to
the DTMF memory channels.
Note: For details, refer to the Advanced Manual (download from the Yaesu website).
