5.5 Monitor function
The (Monitor) button is for temporarily disabling the squelch
which reduces background noise thus enabling you to listen for
extremely weak signals. By doing this, you avoid listening to broken
communication.
To activate the monitor function, hold down the button until you
hear background noise (or else a weak signal). Release the
button when you have finished listening.
If you wish to deactivate the squelch without holding down the
button, press the button for at least 5 seconds, until you hear
two acoustic sounds (beeps), then release the button. The squelch
will remain disabled until you briefly press the button again.
5.6 Selecting transmission power
To extend the battery duty, you can select low transmission power
when transmitting over short distances.
To do this, briefly press the HI/LO button: LOW will appear on
the display (low power is approx. 0.1 W). If you wish to transmit or
receive over long distances or with weak signals, press the HI/LO
button again: LOW will disappear and high power will be set (approx.
0.5W).
The transceiver is factory preset to transmit on high power.
5.7 Compass button
ALAN 445 SPORT is equipped with a precise electronic compass.
When you first switch on of the unit, the compass needs to be
‘calibrated’ as follows:
1) Turn on the radio and hold down the Compass button for at least
3 seconds.
2) “CAli br” will be
displayed.
3) Rotate the radio fully twice
(360°), keeping it perfectly
parallel to the ground (as
indicated in picture 2).
4) Push the Compass button;
“Succes” will be displayed
if the calibration has been
successful or “FAil” in case
it has not been carried out.
We suggest you calibrate the compass each time the batteries are
removed from the battery compartment.
We suggest you calibrate the compass outdoors and in a place far
from magnetic sources.
5.8 Display lighting
Briefly press the button. The backlight is activated for about 10
seconds. If you wish to deactivate it, press the button again.
Display lighting uses additional battery energy. Try to use this
feature in moderation.
5.9 Keypad lock
To activate the keypad lock, hold down the HI/LO button until the
symbol appears on the display. This function deactivates all the
buttons on the front of the transceiver. Pressing one or more buttons
when in this mode will cause an audio signal of three consecutive
beeps. To deactivate the keypad lock, follow the description above
once again.
