Installation Procedure

1. Use the enclosed double-sided tape to temporarily
mount the bracket at the installation location and
then fasten the bracket securely with the enclosed
screws so that it does not loosen or detach due to vi-
brations etc.
Mount the unit securely using commercial stays etc.
if the installation location is weak.
If you are mounting the unit using tapping screws,
pay due attention to the strength of the installation
location and check that the bracket does not detach
easily.

transceiver unit to MMB-90.

To install the MMB-90, before commencing work, first
use the following points as a guide to find a suitable
installation location that will allow the transceiver to be
easily operated.
r Please choose a location that will not affect the op-
eration of the air bag system for cars equipped with
air bags.
r That will not obstruct the field of view in front.
r That will not impede driving.
r That will not result in danger to the passengers in the
assistant driver's seat and rear seats etc.
r That is not exposed to direct sunlight and hot air etc.
