18-5 What next - dealer support

If any apparent fault symptom repeatedly occurs contact
your AOR dealer for advice, have the serial number and
date of purchase to hand. Ensure that you can provide a
detailed description of the fault condition.
Note: The AR5000 is equipped with a Super Capacitor
(large capacity capacitor) to back up the clock. This
enables the built-in clock to be kept running even when
the set is disconnected from power, all other memory data
is stored within the EEPROM which is not affected by
depletion of the back-up capacitor. The clock should be
maintained for approximately 50 hours without supply, if
the set is left disconnected for longer than 50 hours make
sure the clock is keeping the correct time, this can be
noted as the LCD segments will light up momentarily when
the set is connected to the mains.
