2.3 Operating summary
-RKE
① TRANSMITTER's button is pushed.
② TRANSMITTER sends the code by radio frequency.
③ RECEIVER gets the code and decodes it.
④ RECEIVER judges the code whether it is right code or not.
⑤ RECEIVER checks door lock or unlock, trunk state.
⑥ RECEIVER drives the actuator.
- Passive Start
①
the SSB button of SMK is pressed to start the engine.
SHT/SHTS : 4/11
②
The indoor ANT of the car transmits the code via the Low Frequency.
③ Fob(receiver) decrypts the received code from SMK.
④ Fob transmits the code via radio frequency.
⑤ SMK should check the boot state.
⑥ SMK controls a start-up operation and the transition of supply power.
2.3.1 LOCK & UNLOCK
① If LOCK or UNLOCK button is pushed for less than 1 sec,
then TRANSMITTER sends the LOCK or UNLOCK DATA.
② If TRUNK button is pushed for more than 1 sec, then
TRANSMITTER sends the TRUNK DATA.
2.4 Caution
① Danger of explosion if battery is incorrectly replaced.
② Replace only with the same or equivalent type recommended by the
manufacturer.
③ Dispose of used batteries according to the manufacturer's instructions.

Note: This equipment has been tested and found to comply with the limits for CLASS B digital
device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment This equipment generates, uses and can radiate radio frequency energy and, if not
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
correct the interference by one or more of the following measures:
1.1. Reorient or relocate the receiving antenna.
1.2. Increase the separation between the equipment and receiver.
1.3. Connect the equipment into an outlet on a circuit different from that to which receiver is
connected.
1.4. Consult the dealer or experienced radio/TV technician for help.
WARNING
Changes or modifications not expressly approved by the manufacturer could void the
user’s authority to operate the equipment.
“CAUTION : Exposure to Radio Frequency Radiation.
Antenna shall be mounted in such a manner to minimize the potential for human
contact during normal operation. The antenna should not be contacted during operation
to avoid the possibility of exceeding the FCC radio frequency exposure limit.
