LCD. It is normal, for the microprocessor of the AR-ONE generates the 'boot up data'
required to control the receiver.
2-3 Squelch Circuit
In normal use, NOISE SQUELCH is used. However, LEVEL SQUELCH can be selected for
search and scan operations. The LEVEL SQUELCH parameter causes the AR-ONE to
check the signal strength of active frequencies and to only stop when the signal strength is
above a preset level (which is programmable).
To select LEVEL SQUELCH, perform the following steps:
1. Push the FUNC key.
2. Push the "8" key.
3. On the bottom of the LCD, a bar will be displayed. Using the SQL control,
adjust the desired signal level.
4. Push the ENT key to confirm entry.
5. Squelch will open only when the input signal strength is above this set level.
6. To select NOISE SQUELCH, repeat above steps.
2-4 VFO selection
The AR-ONE has ten (10) VFOs being identified as "V-A" through "V-J" on the top left of
the
LCD. The term VFO historically means 'Variable Frequency Oscillator' and today refers
to
a tuneable data store which contains frequency, step, step-adjust, attenuator etc. Pushing
the VFO key each time will select the one VFO out of 10.
