HOMELINK UNIVERSAL TRANSCEIVER

Description

INFOID:0000000001728554

Homelink universal transceiver can store and transmit a maximum of 3 radio signals.
Allows operation of garage doors, gates, home and office lighting, entry door locks and security system, etc.
Homelink universal transceiver power supply uses vehicle battery, which enables it to maintain every program
in case battery is discharged or removed.

Component Function Check

INFOID:0000000001728555

1.

CHECK FUNCTION

Check that system receiver (garage door opener, etc.) operates with original hand-held transmitter.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Receiver or hand-held transmitter is malfunctioning.

2.

CHECK ILLUMINATION

1.

Turn ignition switch “OFF”.

2.

Press each of the transmitter buttons and watch for the red light
to illuminate with each button.

Is the inspection result normal?

YES
