• Read and follow all instructions carefully.

• The garage door opener is designed and tested to offer safe service provided it is installed and operated in strict accordance with the instructions in this manual.

hese safety alert symbols mean WARNING : A possible risk to personal safety or

T property damage exists.

eep garage door balanced. Do not let the

garage door opener compensate for a binding or sticking garage door. Sticking, binding or unbalanced doors must be repaired before installing this opener.

Do not wear rings, watches or loose clothing

while installing or servicing a garage door opener. Frequently examine the door installation, in

particular cable, springs and mountings for signs of wear, damage or imbalance. Do not use if repair or adjustment is needed since springs and hardware are under extreme tension and a fault can cause serious personal injury.

To avoid serious personal injury from entanglement, remove all ropes, chains and locks connected to the garage door before installing the door opener.

Installation and wiring must be in compliance with your local building and electrical codes.

The safety reverse system test is very important. Your garage door MUST reverse on

contact with a 40mm obstacle placed on the floor. Failure to properly adjust the opener may result in serious personal injury from a closing garage door. Repeat the test once a month and make

any necessary adjustments.

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capablities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

The opener must not be used on a wicket door (door within a door).

The Protector SystemTMmust be used for all installations where the closing force as measured on the bottom of the door is over 400N (40kgf). Excessive force will interfere

with the proper operation of the safety reverse system or damage the garage door.

After installation, ensure that the parts of the door do not extend over public footpaths or roads.

Install the wireless wall control (or any additional wall control) in a location where

the garage door is visible, at a height of at least 1.5m and out of the reach of children. Do not allow children to operate push button(s) or transmitter(s). Serious personal

injury from a closing garage door may result from misuse of the opener.

Permanently fasten the Warning Labels in prominent places, adjacent to wall controls

and manual release mechanisms as a reminder of safe operating procedures.

Activate opener only when the door is in full view, free of obstructions and the opener is properly adjusted. No one should enter or leave the garage while the door is in motion.

Do not allow children to play near the door, or door controls.

Disconnect electric power to the garage door opener before making repairs or removing covers.

This opener should not be installed in a damp or wet space exposed to weather.

NOTE: If your garage has no service entrance door, a CM1702 outside quick release must be installed. This accessory allows manual operation of the garage door from outside in case of power failure.

metal door, foil backed insulation, or metal garage siding.

5. The garage door opens and closes by itself:

• Be sure that all transmitter push buttons are off.

• If the wired wall control (optional accessory) is

installed, remove the bell wire from the wired wall control terminals and operate from the ACTIVATION button or transmitter . If this solves the problem, the wired wall control is faulty (replace), or there is an intermittent short on the wire between the wired wall control and the opener.

• Clear memory and re-program all wireless wall

controls and transmitters.

6. The door reverses and stops before opening

completely:

• Is something obstructing the door? Is it out of balance,

or are the springs broken? Remove the obstruction or repair the door.
