The remote control transmitter:
The opener must learn the code of any new remote
control. Page 29 explains how to program your
receiver and how to erase all codes if required. Self
service of your radio controls and remote controls is
not recommended. If service is needed, call the toll-
free number listed on the back page.
The remote control battery:
The green test light will glow and the opener will
operate when the remote control is activated.
If the test light is dim or off, replace the battery.
The 12V battery should produce power for at least a
year.
Dispose of your old battery properly.

IMPORTANT SAFETY INSTRUCTIONS
To reduce the risk of severe injury or death to persons:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. Do not permit children either to operate or to play with the opener. Keep remote control in a
location inaccessible to children.
3. Operate opener only when the door is in full view and free from any obstruction. Keep the door in
sight until it is completely closed. NO ONE SHOULD CROSS THE PATH OF THE MOVING DOOR.
4. Check safety reversal system monthly. See page 26. The garage door MUST reverse on contact
with a 2x4 board laid flat placed on the floor. If an adjustment is made to either the force or the limit
of travel, both adjustments may be needed and the safety reversal system must be checked.
Failure to properly adjust the opener may result in severe injury or death.
5. If possible, use the manual release only when the door is in a closed position. Caution should be
taken whenever the disconnect cord is actuated with the door open. Weak or broken springs may
cause the door to fall rapidly, causing injury or death to persons.
6. KEEP GARAGE DOORS PROPERLY BALANCED. See page 3. An improperly balanced door may not
reverse when required and could result in severe injury or death. Repairs to cables, spring
assemblies and other hardware must be made by a professional garage door person.
7. Disconnect the electric power from the garage door opener before making any repairs or removing
the covers.
