General Information
If you have two transmitters and one does not work it is reasonable to
assume the
problem is in the transmitter. However, when you have one
transmitter and the above hints do not help, the problem may be in the
receiver. When
returning controls to the factory for service it is always
recommended that you send the receiver and
all the transmitters so they
can be serviced and
tested as a set.
When writing to the factory for assistance or when returning a
control for repair be sure to include the following information:
1. RADIO CONTROL MODEL NO.
2. NUMBER OF TRANSMITTERS
3. DOOR OPENER MODEL NO.
AND MANUFACTURERS NAME
4. DATE UNIT WAS INSTALLED
5. NATURE OF DIFFICULTY
SEE PAGE 19 FOR ADDRESS
Door travel is limited by the placement of the chain I imit switch cams. Moving a chain cam one
chain link, varies carriage movement by approximately 1/2 inch {and thus affects door travel
proportionately). Use the transmitter to control the operator when making final adjustments.
