3. While the DC offset error detection condition is being displayed as above, press and hold [1] key for 2 seconds to clear the information about the improper connection, and other detection. Press and hold [2] key for 2 seconds to clear the information about the number of capacitor leaks. (Clear E2PROM) 4. DC offset error display mode is cancelled by resetting. (The last screen will not be retained.) (Note) In this mode, the DC offset error detection display, "Protect" is not shown.

How to clear the programmable security code (Simple security models)
1. While "_ _ _ _" is being displayed, press [ ] key for 3 seconds or longer while pressing the [AUTO] or [TI] keys. (This makes the "_ _ _ _" display disappear.) 2. Input "KCAR", using the remote controller. Press [5] key of the remote controller 2 times (Input for "K") and press [ ] key. Press [2] key of the remote controller 3 times (Input for "C") and press [ ] key. Press [2] key of the remote controller once (Input for "A") and press [ ]key. Press [7] key of the remote controller 2 times (Input for "R") and press [ ] key. 3. The security is cleared and the unit enters STANDBY mode. 4. If wrong codes are input, "_ _ _ _" will be displayed again.

4. After inputting the code, press [ ] key for 3 seconds or longer which causes "RE-ENTER" to be displayed. This is for "confirming" the code. Use the method in the step 3 to re-enter the code. 5. Then, press [ ] key for 3 seconds or longer, which will display "APPROVED". This completes the security code registration

DC OFFSET ERROR
Purpose
Prevent customer's vehicle speakers damages, burnouts, and smoking. Avoid the connected speakers to be burned out, damaged, or to smoke when DC occurs between the audio power amp. + and - outputs. · Although switching between Power OFF and ON (ACC, BU, and Key operation) is valid, switching from Off to ON shall be error until the -com is reset. While power-on, even if the IC2VI DCErr output terminal logic recovered to normal level value, the error condition shall continue. · Prohibit to save the backup/installer memory to E2PROM (nonvolatile memory).

Processing after detection · System status
· At the detection of DC error, error data is to be saved immediately (E2PROM error log save area). · Display the error message on the display. The system shall maintain the current condition, including the operation. Shut down audio system power supply. Set Mute to ON.

Controlling -com terminal
· Set Mute for all channels including for pre-out. · Turn off power IC control system power supply. (Set AMP-Standby function to valid) · Set P-Con output to OFF (Logic by which external AMP unit is turned off).

DC OFFSET ERROR
Cancel Condition
· Press the Reset terminal on the main body. Or set Backup to OFF (Unplug and plug back in the DC connector). The history is maintained (E2PROM data is saved). · If DC error is detected during the capacitor leak detection period, the clearing the error by the reset is limited to 4 times. The startup is inhibited for the 5th time and later reset. ("PROTECT" display has to be blinked.)

The purpose is to shut down audio output. Basically, the logic sets the audio output system signal line when in Standby source.

Key specification
· Other keys than eject and power keys are invalid.

Display specification
· Display the "PROTECT" string and blink all characters at 1Hz. Use the indication below with the highest priority (error message), and maintain the error message even when the source is changed. Display example PROTECT
Blink alternately at 1Hz

Note while in the test mode
· While in the test mode, even if DC leak is detected, it is not written into E2PROM. When an error is detected, the display is enabled.

Other
· Function for checking and clearing data in E2PROM by a given key shall be included. (Used at production dpt. and service center, etc.)
