GETTING

STARTED

Receiving

and

Transmitting

To activate Weather Alert:

1. Press and hold the WH/CH-ALERT key for more

than one second to activate this mode.

2. Return to regular use of the radio. You will hear a

Weather Service beep tone and observe the

flashing “WX Alert” display when a weather alert

signal had been detected followed by the severe

weather alert broadcast. (Figure 9)

3. To cancel the Weather Alert feature, press and hold

the WX/CH-ALERT key or turn the unit off.

Receiving and Transmitting

Whenever the VHF 720 is powered-up (On)
it is in the receiving mode. If the unit is monitor-
ing a channel that is broadcasting, you will hear
that transmission. It is possible to monitor any
channel on any band, but transmission on some
channels is not allowed. Many are receive only
channels, while others are simply not intended for
your category of radio use.

To receive on the VHF 720:

1. Press and release the PWR key to turn the unit on.

2. Observe that the display screen will come on and

the last channel accessed will be displayed. If there

is someone transmitting on that channel, you will

hear their communication and the RX symbol will

appear on the LCD display. You may now select

from the many receiving options.

NOTE: For clearer reception, you can adjust the

volume key up or down and set the squelch

threshold to a level at which the audio will be

enabled.

Power Saving Tip!

To monitor the weather
alert feature and save
battery power:

1. Select a weather
channel.
2. Initiate Weather Alert.
3. Reduce volume to
minimum.
4. Press and hold the
LOCK key.

The audio will mute and
the VHF 720 will wake-up
from a lower power mode
to monitor for the weather
alert tone every 5 seconds.
Pressing any key that is
functional during the
LOCK mode will cancel
the Low Power mode and
switch to regular WX/Alert
Mode. A weather alert tone
from the National Weather
Service will also cancel the
Low Power mode and tune
the receiver to the active
weather alert channel at
mid-volume level.
