VX-3R Operating Manual
“KEY” or “KY+SCN” in step “4” above.
KEY: The beeper sounds when you press any key.
KY+SCN: The beeper sounds when you press a key or when the scanner stops.
Checking the Battery Voltage
The VX-3R’s microprocessor includes programming which will detect the battery type and measure the
current battery voltage.
1. Press and hold in the [TXPO] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 23: DC VLT.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [TXPO] key momentarily to display the battery type and the current DC voltage being
supplied.
Lit: FNB-82LI is in use.
Edc: An external DC source is in use.
4. Press and hold in the [TXPO] key for one second to return to normal operation.
Changing the Channel Steps
The VX-3R’s synthesizer provides the option of utilizing channel steps of 5/8.33/9/10/12.5/15/20/25/50/100
kHz per step (optional values are different by a operating band), as well as an automatic step selection
based on the current operating frequency (“AUTO”), any number of which may be important to your
operating requirements. The VX-3R is set up at the factory in the “AUTO” configuration, which probably is
satisfactory for most operation. However, if you need to change the channel step increments, the procedure
to do so is very easy.
1. Press and hold in the [TXPO] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 82: STEP.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [TXPO] key momentarily to enable adjustment of this Item.
4. Rotate the DIAL knob to select the new channel step size.
5. When you have made your selection, press the PTT switch to save the new setting and return to
normal operation.
R.F. Says: 1) 9 kHz steps are available only when receiving on the BC band.
2) 8.33 kHz steps are available only when receiving on the Air band.
3) While operating on the BC band, you may only select channel steps of 9 kHz or 10 kHz; the other step
selections are disabled.
4) 5 kHz steps are not available for use on 250 - 300 MHz, nor above 580 MHz.
