Below is how to release registered security codes.
■How to release security codes
In the security code input screen (CODE ✽✽✽✽ ), after resetting to restart, while holding down [1] key, press [6] key for 2 seconds
or more. Then, the character “C”is displayed at the right end of the security code input screen.
In this condition (CODE ✽✽✽✽ C), using q, w, e, and r keys of the remote controller, input “KCAR”in the “✽✽✽✽”section.
After inputting the characters, press [PLAY/PAUSE] key once to confirm.Then, the registered code is released and “CODE OK!”is
displayed.
RELEASING SECURITY CODES
ADJUSTMENT
Panel Position Registration
qIn the test mode, the panel position registration mode can be entered by pressing [ATT] key for several seconds.
Display :STAND BY
wPress [OPEN/CLOSE ( )] key on the remote controller once, and wait for the panel to fully open.
Confirm that the panel is pushed out to designated position, and then register position.
Display :OPEN CHECK→STAND BY→OPEN ENTRY (BEEP 3 times)
e(After position registration) With the panel fully open, place the panel position registration jig on the set side.
Press [CLOSE ( )] on the remote controller, and close the panel.With the jig in-between panel and sub-panel, register position.
(For this, jig must be held firmly with a hand.)
Then, press [ATT] key for several seconds and move out of the registration mode.
In order to remove the jig, press [ANGLE] key.This makes the panel to open slightly and the jig can be taken out.
Then, press [ANGLE] key to put the panel back into original position.
Display :STAND BY→CLOSE CHECK→STAND BY→CLOSE ENTRY (BEEP 3 times)
Caution : When “OPEN ENTRY/CLOSE ENTRY”is displayed, the position registration is complete.
Confirm that this is displayed before moving on to the next operation.
