The CATS alarm system is not for the car. its for the Radio/cassette system.

Basically if anyone removes the power supply from the radio, and this includes disconnecting the vehicle battery, you will need to input a code in order to re arm the radio.

Should you input the code three times incorrectly the radio will lock out and be totally unusable.

The code is specific to the radio serial number and should you lose it only an authorised dealer can unlock the radio.

check your hand manual it will tell you all the functions of your alarm system and how they work
