Troubleshooting

Before you start considering your unit to be faulty:
Read this Service Instruction manual once again and make sure that the problem is not
caused by weak batteries or by incorrect application.
Check to see if the batteries are positioned correctly with regard to their polarity.
If a problem persists, try to initialize the system by removing the battery from the battery
holders in the receiver, then use a metal tool (e.g. a screwdriver, scissors, etc.) and
short-circuit both contacts – battery holders for about 2 seconds. Reinstall the battery. The
unit emits a beep confi rming that the battery is installed with correct polarity.
Unless this helps, program your receiver again. Clear the previous code in the memory and
then match your receiver with the remote controller according to instructions in this
manual.
If the problem persists, contact your supplier.
