the front center of the hood to ensure that
both latches engage.
WARNING!
Your motorized door or gate will open and
close while you are programming the
universal transceiver. Do not program the
transceiver if people, pets or other objects
are in the path of the door or gate. Only use
this transceiver with a garage door opener
that has a “stop and reverse” feature as
required by Federal safety standards. This
includes most garage door opener models
manufactured after 1982. Do not use a
garage door opener without these safety
features.
Vehicle exhaust contains carbon monoxide,
a dangerous gas. Do not run your vehicle in
the garage while programming the trans -
ceiver. Exhaust gas can cause serious
