d. While changing the battery of the remote, make sure to use the correct type and
position it in the correct direction. It is recommended to change the battery at
least every 6 months. For HA-12T: use 27A alkaline battery.
e. If the car is not driven for a long time, it is recommended to start the engine
regularly to make sure the battery of the car can supply enough electricity to
the system.
f. If the car stops supplying power to the system (either the power supply system
has been cut or the car battery has been run out.), the siren will start sounding by
using its own back up battery until the battery is run out. In this case, unexpected
damage may possibly happen on the back up battery of the siren. To avoid the
damage, always make sure the car battery can provide enough electricity for the
recharging of the siren.
g. Contact the system provider for any unsure action on the system.
Warning!
Any unauthorised alternations or additions to the system my lead to the
malfunction of the system, which will invalidate the certificate and guarantee of
the product.
