TX POWER

To change the transmission output power:

Press [LOW].

•Each time you press [LOW], the icon cycles from H ➞ L ➞ EL, and then goes back to H.

The output power varies depending on the battery type and operating voltage. The table below shows the approximate output power when the transceiver operates with different types of battery or DC power source.

Battery	Output Power	Output Power (Approx.)
Type	Selection	TH-F6A/ TH-F7E
BT-14	H	0.5 W
	L	0.3 W
(6.0 V)
	EL	0.05 W
PB-42L	H	5.0 W
	L	0.5 W
(7.4 V)
	EL	0.05 W
DC IN	H	5.0 W
	L	2.0 W
(13.8 V)
	EL	0.5 W

Note:

◆You can store the TX Power settings independently for A and B-band.

◆If the DC IN voltage exceeds 14.5 V DC and “H” (High Power) is selected, “H” icon blinks and the output power is reduced to “L” level (Low Power) automatically.

VOLUME BALANCE

While you are receiving on the A and B-bands at the same time, you may sometimes feel that the audio output on either band is too loud. You can adjust the volume balance level of the bands.

1Press [BAL].

• The balance scale and blinking cursor appear.

2Turn the Tuning control or press []/ [] to change the volume balance level of the bands.

A-band Max Max Max Att Mute

B-band Mute Att Max Max Max

Max: Maximum, Mute: Muted, Att: Attenuated

3Press [] or [MNU] to store the setting. Otherwise, press [] to cancel without changing the current settings.

Note:

◆If TNC is selected for Menu No. 9 (SP/MIC JACK), the squelch status (REM/ SQ) changes based on your volume balance settings {pages 45, 46}.

◆You can also set the volume balance while in Single Band Operation {page 40}.

VOX (VOICE-OPERATED TRANSMIT)

VOX eliminates the necessity of manually switching to the transmit mode each time you want to transmit. The transceiver automatically switches to transmit mode when the VOX circuitry senses that you have begun speaking into the microphone.

When you operate the VOX function, you must use an optional accessory, HMC-3 or KHS-21. Because both the internal speaker and microphone are too near to be used for the VOX function.

To turn the VOX function ON:

Press [F], [SQL].

•“VOX” appears.

•To exit VOX mode, press [F], [SQL] again.

Note:

◆You cannot turn the VOX function ON while the Visual Scan {pages 26, 27} is activated.

◆While the VOX function is ON, the Menu No. 28 (PACKET) settings return to 1200 bps {page 45}.

◆While the VOX function is ON, you cannot use [ ]/ [ ]/ []/ [] to adjust other settings, such as the frequency and operating band.

◆While in the Menu mode {page 9}, the VOX function is disabled temporarily.

◆Since the VOX circuit must detect the presence of your voice, you may notice a slight delay in transmission. The very first part of your message may not be transmitted.

◆Turn the HMC-3’s VOX function OFF when you use the internal VOX function.

VOX GAIN

To enjoy the VOX function, take the time to properly adjust the VOX Gain. This level controls the VOX circuit to detect the presence or absence of your voice. There are 2 ways of adjusting the VOX Gain.

When the VOX function is already ON:

1Press []/ [] to select the desired VOX Gain from 0 (least sensitive) to 9 (most sensitive).

•The VOX Gain level numbers, “G: 4” changes accordingly (default is 4).

2While speaking into the microphone using your normal tone of voice, adjust the VOX Gain by

pressing []/ [] until the transceiver reliably switches to transmit mode each time you speak.

•The setting should not allow background noise to switch the transceiver to transmit mode.
