Match code switches (2-9)
between old remote control and
new remote control (Code switch
#1 on the 3-button remote
control is dormant)
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).

WARNING
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.
