If one of following message is displayed
antenna will not tune:
Typical causes are:
- Excessively large conductive luggage loaded onto
roof rack. Remove luggage and retune the antenna.
- Accidental contact of the loop with a large metal
object. Remove the object and retune the antenna.
- Damage to one of three flexible low loss strip cables
that connect the loop, Two cables are located under
plastic guard plate at rear loop axle, the third cable is
located under high voltage cover at the front. Change
damaged cables.
- Damage to RF coaxial cable, change if required.
- Battery voltage is too low. The line voltage should
never drop below 11.5 Volts. Excessively long or
insufficient power cord size, bad or no contact
between radioset grounding post and the vehicle
chassis.
Antenna will not tune when transmitted frequency
from your transceiver is out of antenna frequency
limits. Change frequency. Please refer Chapter 6.1
Frequency range.
This message will appear in case of RF coaxial cable
cut off or damage to your transceiver circuit. Check
the cable and the transceiver. Replace if required.
The typical time required for the loop to change its
position is 15 seconds. In case the loop is not arrived
in either UP or DOWN position within 30 seconds,
the warning sound and screen shot as shown will
appear. This situation can be caused by wrongly
tied luggage or accident obstacle and may lead in
damage to the loop or misalignment of the servomotor
