CAUTION
When programming the HomeLink
Universal Transceiver, you may be
operating a garage door or other
device. Make sure people and ob-
jects are out of the way of the ga-
rage door or other device to pre-
vent potential harm or damage.
Do not use this HomeLink Univer-
sal Transceiver with any garage
door opener that lacks the safety
stop and reverse feature as re-
quired by federal safety standards.
(This includes any garage door
opener model manufactured before
April 1, 1982.) A garage door open-
er which cannot detect an object
(signaling the door to stop and re-
verse), does not meet current feder-
al safety standards. Using a garage
door opener without these features
increases risk of serious injury or
death.
This device complies with Part 15 of the
FCC Rules and with RSS- 210 of the IC
Rules. Operation is subject to the fol-
lowing two conditions: (1) This device
may not cause harmful interference, and
(2) this device must accept any interfer-
ence received, including interference
that may cause undesired operation.
WARNING: This transmitter has been
tested and complies with FCC and IC
rules. Changes or modifications not
expressly approved by the party re-
sponsible for compliance could void
the user's authority to operate the
device.To use the auxiliary boxes, open the
lids as shown in the following illustra-
tions.
CAUTION
To reduce the chance of injury in
case of an accident or sudden stop,
always keep the auxiliary box
closed while driving.
Type AÐIt is designed for holding
a light objects, do not place any
heavy objects in it. Heavy objects
may cause the holder to open and
contents to fly out resulting in inju-
ries.
NOTICE
Type AÐDuring hot weather, the inte-
rior of the vehicle becomes very hot.
Do not leave anything flammable or
deformable such as a lighter, glasses,
etc. inside.
