Clock Audio CU2 - Manual (Page 2)

FAULTS WITH ONE OF THE TRANSMITTERS
Battery Fault
 Red flashing light will show immediately if alkaline or other non rechargeable batteries have
been used. The intelligent charger will automatically stop any charging of these batteries
thereby preventing any harm to both the charger or battery pack. Recommended rechargeable
batteries are NiMH 2700.
 During the charging process the Red flashing light will show if one of the batteries have
failed/become faulty and charging of the batteries will automatically be stopped. As you will
not be able to tell which one of the batteries has failed, it is important to replace both of the
batteries at the same time.
 Red flashing light may show if the batteries are totally flat. Rechargeable batteries should
never become totally flat and usually this will render the batteries unusable. Try removing the
battery pack for 30 seconds, then reconnecting the battery pack to the charger as some times
it may be possible to recover these batteries. Otherwise replace both batteries.
Charger fault
1. The battery / charging unit has been moved or sustained shock / vibration causing a brief
disconnection between the charger / battery pack.
2. Battery or charger contacts have become contaminated and require cleaning. Using a
cotton bud dipped into Isopropyl alcohol or mentholated spirits gently clean the battery
and charger contacts.
3. The supply to the charger may have briefly received a noisy or spiked supply. The charger
contains a failsafe circuit preventing any damage occurring to the Batteries / wireless
circuitry.
4. Battery that is intermittently becoming faulty.
IMPORTANT: After checking all above remove the battery pack and wait for 30 seconds
before reconnecting the battery pack to the charger. The red light should no longer be
flashing.
Do not use any other types of batteries in the models CW9004T CW9005T CW9006T other than the
supplied GP2700 batteries. The supplied batteries have been matched for optimum performance for
both the CU2 charger and transmitter. Failure to use the correct rechargeable batteries may give rise
to faulty charging and substandard operation of the radio transmitter. Replacement batteries are
available from Clock audio please contact your agent should you require replacement batteries.
