•
Press and hold the orange [PWR] Key for two seconds to turn the radio on or off.
‚
When you turn on the radio, a "Welcome" message will appear on the display for two
seconds. After this interval, the frequency display will appear. Using the Menu system,
you can change the "Welcome" message yourself; see page 40 for details.

•
Rotate the VOL knob to adjust the receiver's audio volume. Clockwise rotation of the
VOL knob increases the volume level.
‚
The VR-500's Squelch system allows you to mute the receiver's audio output when no
signals are being received. This reduces battery consumption, and reduces annoying
background noise.
ƒ
To set the squelch, turn the SQL knob fully counter-clockwise, then turn it clockwise
just past the point where background noise is silenced. Do not rotate the SQL knob
much beyond this threshold point; if you do, the receiver will not respond to weak
signals.
A special "RF Squelch" feature is provided on this radio. This feature allows you to set the
squelch so that only signals exceeding a user-defined signal level will open the squelch.
To set up the RF Squelch circuit for operation, use the following procedure:
•
From the VFO mode, press the [ENT(SET)] key while pressing the [FUNC] key to
activate the "Set" (Menu) mode.
‚
Rotate the DIAL knob to select Menu #19 "[RF Squelch]."
ƒ
Rotate the DIAL knob while pressing the [FUNC] key to se-
lect the desired signal strength level for the RF Squelch thresh-
old (1 ~ 9 or OFF).
„
Press the [ENT(SET)] key while pressing the [FUNC] key to save your new setting
and exit to normal operation.
The VR-500 automatically selects a default receiving mode according to the frequency
band on which you are operating. However, many bands (especially HF Shortwave) may
use a variety of transmission modes in a particular frequency segment.
If you want to change the receiving mode, press the [0(MODE)] key while pressing the
[FUNC] key. The receiving modes available are:
NFM è WFM è AM è LSB è USB è CW è NFM • • •
