Weather Alarm
Medium-loud, continuous, medium-pitched series of one-half (
1
⁄2) second beeps
spaced one-half (
1
⁄2) second apart — sounds when weather alert is turned On
and NOAA sends a 1050 Hz weather alert tone on the selected weather channel. Press
any button to turn it Off.
Power On-Off
Transceiver power can be turned On or Off by the On-Off Power/Volume
knob on the transceiver.
To Turn Your Radio On Or Off:
1. Rotate the Off Power/Volume knob clockwise to turn on
the transceiver. To turn off the transceiver, rotate the Off
Power/Volume counter clockwise until a “click” is heard.
When the radio is powered On, the confirmation tone
will sound.
The radio will return to the settings in effect when it was
last powered Off, the LCD will show the corresponding
information, and all controls will be operative. The radio
will then be in Standby mode.
Volume
The On-Off Power/Volume knob on the transceiver controls the
speaker volume. The volume adjustment applies only to what
you hear from the speaker and does not affect the volume of
your outgoing messages. That is controlled by the circuitry of
your radio. The volume bar graph will be shown to indicate
the volume setting. 2 seconds after finishing the volume
adjustment, the radio will return to the Standby mode.
To Increase The Volume:
• Turn the On-Off Power/Volume knob clockwise.
To Decrease The Volume:
• Turn the On-Off Power/Volume knob counter-clockwise.
Squelch
Squelch control filters weak signals and radio frequency noise so that you can more
clearly hear the signals you want. You can think of it as a variable barrier that blocks
what you don’t want to hear.
