unipole, Yagi, etc. When sighting the antenna, avoid power cables. Ensure that you do
not confuse the antenna and other IF output connectors as they are closely located.
Operating anomalies
Should the AR-ONE appear to behave strangely, normal operation may be easily
achieved by resetting the microprocessor. Two scenarios may be encountered due to
power transients etc:
1. Symptom:
Action:
Remove any connection to external power and leave it for
approximately 30 seconds. Reconnect power and switch on again.
Normal operation should be restored but the last used frequency will be lost, the
AR-ONE will restore the last but one frequency to
display.
2. Symptom:
Action:
Try the suggestions given in (1) then hold the ESC key while
powering up the AR-ONE to 'Soft reset' the microprocessor.
1-3 Attention while operating
1. Certain key operation are acted upon when the key is RELEASED, not while it
is pressed. Allow time for the AR-ONE to register such actions before pressing
another key.
2. The keylock (LOCK) is intentionally made to be difficult to operate to prevent
accidental operation. To release keylock, the LOCK key has to be held for more
than one second, the key icon on the LCD confirms operation. The LOCK is
disabled during keying sequences (such as when entering frequencies).
3. If a key sequence is not completed, the microprocessor will automatically
abort
most operations after about 90 seconds of keypad inactivity.
4. Currently displayed VFO data is saved at power down (to increase speed of
operation and to reduce write cycles). For this reason, if the AR-ONE is powered
down using the PWR/VOL control or external power is removed, the last
displayed frequency will be lost and the frequency used prior to this will be
displayed when next powered up.
Terminology – Search & Scan
LCD remains on, no control of the keypad.
The AR-ONE fails to power up.
