OUCG8D-522M-AKeyless Entery Transmitter

2. User’s manual (provisionally) 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 in the ignition switch. UNLOCK When you push the UNLOCK button once , only the driver’s door unlocks. The remaining door unlock when you push the button a second time. If you unlock the doors with the remote transmitter, but do not open any of the doors within 30 seconds, the doors will automatically relocked. You cannot unlock any of the doors with the remote transmitter if the key is in the ig n i t i o n s w i t c h . TRUNK When you push the TRUNK buttons, open the trunk. PANIC (anti-theft protection) When you push the PANIC button, when the vehicle disarming. Then start sounding the horn and flushing the hazard lamp intermittently. It continues 3 minutes unless pressing any remote control switch. CAUTION The remote control switch is a precision electronic device. Therefore pay attention to the following: Do not impose shock on the remote control switch. Keep the remote control switch dry. Do not disassemble the remote control switch. When the remote control switch is opened, keep water, dust, etc, off its inside. In addition, do not touch the precision electronic device. -2- -

 ! CAUTION The remote control switch is a precision electronic device. Therefore, pay attention to the following:  Do not impose shock on the remote control switch.  Keep the remote control switch dry.  Do not disassemble the remote control switch. Your keyless entry system operates on a radio frequency subject to Federal Communications Commission (FCC) rules and Industry Canada rules. This device complies with Part 15 of the FCC Rules. Operation is subject to the following tow 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 of the device. “Complies with RSS-210 of Industry Canada.” NOTICE This equipment has been tested and found to comply with the limits for a Class B 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 not installed and used in accordance with the instruction, may cause harmful interference to radio communications However there is no guarantee that interference will not occur in particular installation. If this equipment dose cause harmful interference to radio or 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. FCC WARNING Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

From: [email protected] Sent: Thursday, July 03, 2003 3:08 AM To: [email protected] Cc: [email protected] Subject: The ID number of the modified product Dear Mr.Kuo I will reply to you on the e-mail you sent to Ms.Itatsu. 1.FCC/TCB (1) Question #1: The FCC ID number listed in the test report The test report which we have sent you on May is for the modified product. This test report is not same for original product " G8D-522M-A". When we offered the test of the modified product to the test laboratory, we thougt that the same ID can be used for the modified product. So FCC ID on the test report has been typed as "E4EG8D-522M-A". (2) Question #2: The Proposed FCC ID label format We attach the revised label. Please see it. (3) Question #3: User manual does not contain information We attach the caution. Please see it. Best regards Yasuhide Yomo

Features 5.1 Transmission frame The transmission begins immediately in case of LOCK or UNLOCK button is pressed. The transmission frame consists of the six data frame. The transmission data frame consists of 63 bits length. The first 8 bits comprise the Synchronous region. The second 50 bits are the vehicle identification region. The third 4 bits are for each buttonfunction. The last 1 bit make up the ending region. 16 million different identification codes are available. The security code is always changed in case of any of the buttons is pressed. The transmission time is typically 600 milliseconds. 5.2 Battery saving To prevent the battery exhaustion, the microcomputer of the transmitter is usually inactive. When the button will be pressed, the microcomputer wakes up immediately and judges which button is pressing. Then the microcomputer constructs the transmission frame and radiates it from the antenna. After transmitting, the microcomputer switches stand-by mode by itself. -5- -
