Make sure to ground the unit securely to the vehicle chassis ground.
Do not remove the top or bottom covers of the unit.
Do not install the unit in a spot exposed to direct sunlight or excessive heat or the possibility of water splashing.
Do not subject the unit to excessive shock.
When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause the unit to malfunction.
To prevent short circuits when replacing a fuse, disconnect the wiring harness first.
