and shall give priority to the safety of all passengers in the vehicle.
Please keep this product in a ventilated, dry position to avoid
environmental damage (moisture, gray curtain, food, liquid, direct
exposure to sunlight, etc.). To avoid magnetic field interference and
damage, please stay away from other electronic products (such as
on-board DVD, air conditioner, etc.) when installing the host.
Power must be turned off before installing amplifier and speaker
Please confirm that the connection, power supply and other matters of
the low-frequency alarm system meet the requirements of the user
manual.
When moving the low-frequency alarm system, all power should be
disconnected, and hot- plugging is not allowed.
Amplifier and speakers must match to work properly.
Do not connect the alarm devices to the car battery until all parts are
installed and no short circuit.
When approaching or connecting the battery, protective measures

obstacles;
Do not install the speaker where it may interfere with the operation of
the airbag sensor;
Two loudspeakers should be connected in parallel when installation.
As the low frequency is an efficient infrasound, it cannot be activated
continuously.
