Transmission; Power Output Setting; Ptt Locking - Yaesu FT-7100M Operating Manual

To transmit, simply close the PTT (Push To Talk) switch on the microphone when the
frequency is clear. Hold the microphone approximately 25 mm (1") from your mouth, and
speak into the microphone in a normal voice level. When your transmission is complete,
release the PTT switch; the transceiver will revert to the receive mode.
During transmission, the "main" band BUSY/TX indicator changes from Green to Red, and
the S&PO meter segments rise up according to the power output selected.

Power Output Setting

Four power output levels are available on this transceiver: 5 watts (LOW), 10 watts (MID 2),
20 watts (MID 1) and 50 watts (VHF) or 35 watts (UHF) on HIGH.
To change the power level, press the [ LOW ] key. Each time you press the [ LOW ] key, the
new power level will be displayed for a few seconds, then the regular display mode will
reappear.
The power level can be set independently for each band. Also, the power level may be stored
in a memory register, if desired.

PTT Locking

The PTT circuitry may be locked out, so as to prevent unau-
thorized or otherwise undesired transmission.
To lock out the PTT circuitry and thus prevent transmission:
1. Press and hold in the [ BAND ] key for 1/2 second to acti-
vate the "Menu" mode.
2. Rotate the Main Dial knob to select Menu # 16 (LOCKT).
3. Press the [ BAND ] key momentarily to enable changing of this Menu item.
4. Rotate the Main Dial knob to select the desired lock mode:
BAND A : PTT will be disabled on VHF only;
BAND B : PTT will be disabled on UHF only;
BOTH: PTT will be disabled on both the VHF and UHF bands; or
OFF : PTT lock feature is off.
5. Press and hold in the [ BAND ] key for 1/2 second to save the new setting and exit to
normal operation.
To cancel the PTT lock feature, select "OFF" in step 4 above.
