TRANSMITTING

1To transmit, press and hold the PTT switch and speak into the microphone in a normal tone of voice.

•Indicator A or B lights red depending on which band you have selected.

•The battery meter appears to show the current relative battery charge.

•Speaking too close to the microphone, or too loudly, may increase distortion and reduce intelligibility of your signal at the receiving station.

2When you finish speaking, release the PTT switch.

Time-Out Timer: Holding down the PTT switch for more than 10 minutes causes the transceiver to generate a beep and stop transmitting. Release, then press the PTT switch to resume transmitting. You cannot switch this function OFF.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

◆ The recommended duty cycle is 1 minute of transmission and

 

1

 

 

 

3 minutes of reception. Extended transmissions in the high

 

2

 

 

 

power mode may cause the back of the transceiver to get hot.

 

 

◆ Transmitting with the supplied antenna near other electronic

 

 

3

 

 

 

equipment can interfere with that equipment. Also, transmitting

 

 

 

 

 

near a poorly regulated power supply, that is not recommended

 

4

 

 

 

by KENWOOD, may cause the power supply to output an

 

5

 

 

 

extremely high voltage. This voltage could damage both your

 

 

 

 

transceiver and any other equipment connected to the power

 

6

 

 

 

supply.

■ Selecting Output Power

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

10

 

Selecting lower transmit power is a wise method to

 

11

 

reduce battery consumption, if communication is still

 

12

 

reliable. You can program a different power for band

 

 

 

A and B.

 

 

 

 

 

 

 

 

 

 

 

 

13

 

Press [F], [MENU] to select high (default), low, or

14

 

economic low power (lowest).

• “H”, “L”, or “EL” appears to show the current selection.
