Call up security register mode by pressing the CLK key.3. Enter the code with the Preset 1/2/3/4 keys.For example, to enter the number,

42、“3510”.- Press the Preset 1 key 4 times.- Press the Preset 2 key 6 times.- Press the Preset 3 key 2 times.- Press the Preset 4 key 1 time.4. Hold down the DISP key for at least 3 seconds and themessage, “RE-ENTER” appears, so once again enterthe code according to Step 3 above.5. Hold down the DISP k

43、ey for at least 3 seconds, and themessage, “APPROVED” appears.6. Cancel test mode. (See, 2. How to cancel the test mode.)Note: All clear cannot be performed on the security codefor this model. Simple way to clear the security code (K type only)1. During code request mode, press the VOL UP key for at

44、least 3 seconds while holding down the DISP key.(- will disappear)2. Enter, “KCAR” with the remote controller as describedbelow. (Same as on 00 model.)Press the remote controller 5 key twice, and press theTrack Up key. (Enters a “K”)Press the remote controller 2 key three times, and pressthe Track U

45、p key. (Enters a “C”)Press the remote controller 2 key once, and press theTrack Up key. (Enters an “A”)Press the remote controller 7 key twice, and press theTrack Up key. (Enters an “R”)3. Security function is canceled and unit sets to All-Off mode.4. Code request mode appears if a mistake was made

46、inentering the numbers. Mask key write method on initialized EEPROM1. While holding the FM key and the preset 6 key, reset theunit.2. Press the CLK key to call up mouse key register mode.The message, “TRANSMIT 1” appears. The display atthis time shows “ rather than “ ”.3. Face the mask key towards t

47、he photosensor and holddown for half a second or longer.4. When “TRANSMIT 2” appears, again hold down the maskkey for at least half a second. The first and second countercodes are not compared at this time.5. When the message, “APPROVED” appears, the writingis complete. The demo mode is set at this

48、time and testmode is canceled.Note: Just as with the previous model, if 30 minutes elapsesand the code is not written, then an error is issued andpower-OFF is triggered. How to initialize the mask key (Return to factory settingsfrom mask key write permit status.)1. While holding the FM key and the p

49、reset 6 key, reset theunit.2. The message, “TRANSMIT 1” appears and mask keyrequest mode is called up. The display at this time shows“* * ” rather than “ ”.3. Cancel the mask key on the remote control by holdingdown for at least 3 seconds.4. When “TRANSMIT 2” appears, again hold down the maskkey for at least 3 seconds.5. When the message, “APPROVED” appears, the maskkey is canceled, demo mode is set, test mode is canceled,and the factory settings restored. How to All-Clear the mask key
