Transmitter, RF Keyless Entry System
FCC Compliance statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection
against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if no t installed and used
in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this
equipment does cause harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
— Reorient or relocate the receiving antenna.
— Increase the separation between the equipment and receiver.
— Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
— Consult the dealer or an experienced radio/TV technician for help.
Caution:
Any changes or modifications to the equipment not expressly approved
by the party responsible for compliance could void your authority
to operate the equipment.

Constitution of the Radio Frequency Keyless Entry
System for vehicle
The radio frequency keyless entry is a system that it controls locking and unlocking the door and t h e
trunk and the panic by wireless remote controller. This system consists of three components. The TRANSMITTER is
a device that transmits the signal when the button is pressed. The transmission signal consists of several
synchronous codes, unique identification code, security code and function code and crc code. The RECEIVER is
fixed inside the vehicle. It works intermittently to prevent the battery exhaustion. When the receiver detects the
synchronous code, it runs continuously to receive the signals completely. After receiving the signal, the receiver
decides which operation will be performed.
The user can select the following operations by pressing the button of the remote transmitter.

REMOTE TRANSMITTER
You can lock and unlock your vehicle with the remote transmitter.
LOCK
When you push the LOCK button, all the doors will lock.
You cannot lock any of the doors with the remote transmitter if any door is open or the key is the ignition switch.
UNLOCK
When you push the UNLOCK button, all the doors will unlock.
You cannot unlock any of the doors with the remote transmitter if any door is open or the key is in the
ignition switch.
TRUNK
When you push continuously the TRUNK button during 0.5s, TRUNK will open.

5.Features
5.1 Door lock control
The LOCK relay in the receiver drives the door lock actulators to "LOCK"-side when LOCK button of
transmitter was pressed. The UNLOCK relay in the receiver drives
5.2 Battery saving
To prevent the battery exhaustion , the micro-computer of the transmitter is usually inactive. When the button
will be pressed, the micro-computer wakes up immediately and judges which button is pressing. Then the
micro-computer constructs the transmission frame and radiates it from the antenna .After transmitting, the
micro-computer switches stand-by mode by itself.
6. Derivatives
