NOTE: Code switch #1 on

the 3-button remote

control is dormant, when

used with a single-button

remote control. Set code

switch #1, in the 

single-button remote

control, to match the push

button selected on the 

3-button remote control

(Figure 2).

To prevent possible SERIOUS INJURY or DEATH from a

moving gate or garage door:
• ALWAYS keep remote controls out of reach of children.

NEVER permit children to operate, or play with remote

controls.

• Activate gate or door ONLY when it can be seen clearly, is

properly adjusted, and there are no obstructions to door

travel.

• ALWAYS keep gate or garage door in sight until completely

closed. NEVER permit anyone to cross path of moving gate

or door.
