DESCRIPTION AND OPERATION

Electrochromic Mirror
The electrochromic mirror automatically dims to reduce glare from the headlights of following vehicles in dark or low
light conditions. In addition to dimming the interior mirror, the electrochromic mirror circuits also control the dimming
of the two door mirrors, via positive and negative connections between the interior mirror and each door mirror.
A light sensor on the front of the mirror monitors ambient light at the front of the vehicle and a light sensor in the mirror
glass monitors the light coming from behind the vehicle. When the light from behind the vehicle exceeds the ambient
light level, the electrochromic circuits simultaneously dim the interior and door mirrors. Dimming is inhibited when
reverse gear is selected. The interior mirror is provided with a reverse gear signal by the Light Check Module (LCM).
Universal Transmitter
The universal transmitter can operate up to three home or office remotely operated systems (e.g. garage door/gate
openers, lighting and security systems), replacing the individual hand held transmitters required for each system. The
universal transmitter can learn the radio frequency codes of most current transmitters.
WARNING: The universal transmitter must not be used with any garage door that lacks safety ‘stop’ and
‘reverse’ features, as required by federal safety standards (this includes any garage or door opener model
manufactured before April 1 1982). A garage door opener which cannot ‘detect’ an object in the path of a
closing door and then automatically ‘stop’ and ‘reverse’ the door, does not meet current federal safety
standards. Using a garage door opener without these features increases the risk of serious injury or death.
The universal transmitter incorporates three buttons, one for each channel, and an amber LED installed on the
underside of the interior mirror. When one of the buttons is pressed the universal transmitter outputs the radio signal
programmed for the related channel (if any) and illuminates the LED to confirm transmission.
Hand held transmitters are programmed into the universal transmitter as follows:
1 Turn the ignition switch to position II.
2 Press and hold the two outer buttons of the universal transmitter until the LED begins to flash, then release the
buttons. This initialises the universal transmitter and erases previous settings from all three channels.
WARNING: When programming the universal transmitter in the vicinity of the affected system, the system
will operate. If the system controls garage doors or gates, ensure they are clear of people and objects
to prevent personal injury or damage to equipment.
3 Place the signal emitting end of the hand held transmitter against the underside of the interior mirror.
4 Simultaneously press and hold the activation button on the hand held transmitter and the chosen button of the
universal transmitter. When the LED of the universal transmitter flashes rapidly, indicating the channel has been
programmed, release the buttons.
NOTE: The LED flashes slowly at first and can take up to a minute before it flashes rapidly.
5 To programme another channel on the universal transmitter, repeat steps 3 and 4.
6 Turn the ignition switch to 0.
The radio signals used to operate some home/office systems incorporate a code protection feature. After a channel
has been programmed from the hand held transmitter, these systems will need to be trained to accept the signal from
the universal transmitter. To check if a system is code protected, press the appropriate universal transmitter button.
If the LED flashes rapidly for 1 to 2 seconds, before illuminating permanently, the system has a code protection
feature.
The system is trained to the universal transmitter, as follows:
1 Locate the training button on the system receiver. Refer to the system's literature for details.
2 Press the training button on the system receiver for 1 to 2 seconds.
3 On the vehicle, press and hold the appropriate universal transmitter button. When the amber LED stops flashing
rapidly (1 to 2 seconds), indicating training is complete, release the button.
