REMOTE ENTRY SYSTEM
The Integrated Keyhead Transmitter (IKT) complies with part 15 of the
FCC rules and with RSS-210 of Industry Canada. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to
operate the equipment.
The typical operating range for your IKT is approximately 33 feet
(10 meters). A decrease in operating range could be caused by:
•weather conditions,
•nearby radio towers,
•structures around the vehicle, or
•other vehicles parked next to your vehicle.
The IKT allows you to:
•remotely unlock the vehicle
doors.
•remotely lock all the vehicle
doors.
•remotely open the trunk.
•activate the personal alarm.
•arm and disarm the perimeter
anti-theft system.
•operate the illuminated entry
feature.
The remote entry lock/unlock feature operates in any ignition position
except while the key is held in the start position. The panic feature
