VX-3R Operating Manual
1. To transmit, press the PTT switch, and speak into the front panel microphone (located in the upper
left-hand corner of the speaker grille) in a normal voice level. The TX/BUSY indicator will glow red
during transmission.
2. To return to the receive mode, release the PTT switch.
3. During transmission, the relative power level will be indicated on the bar graph at the bottom of the
LCD; full scale deflection confirms “High Power” operation, while deflection of two bars indicates “Low
Power” operation. Additionally, the “LOW” icon will appear at the bottom of the display while operating
on the “Low Power” setting.
4. If you’re just talking to friends in the immediate area, you’ll get much longer battery life by switching to
Low Power operation. To do this, press the [TXPO] key so that the “LOW” icon appears at the bottom
of the display. And don’t forget: always have an antenna connected when you transmit.
Transmission is possible only on the 144 MHz and 430 MHz bands.
R.F. Says: 1) The VX-3R is smart! You can set up Low power on 144 MHz band, while leaving 430 MHz on
High power, and the radio will remember the different settings on both bands. And when you store
memories, you can store High and Low power settings separately in each memory, so you don’t waste
battery power when using very close-in repeaters!
2) When you are operating on the Low power setting, you can press the [F/W] key, when press the PTT
switch, to cause the VX-3R to transmit (temporarily) on High power. After one transmission, the power level
will revert to the previously-selected (Low power) setting.
