Max with the Track Up/Down keys.
• Fader is adjusted in 3 steps of Rear Max/Center/Front
Max with the Track Up/Down keys.
• HPF is adjusted in 2 steps of Through/220 Hz with the
Track Up/Down keys.
• LPF is adjusted in 2 steps of Through/120 Hz with the
Track Up/Down keys.
• Bass f, Bass Q, Bass EXT, Middle f, Middle Q and Treble
f are not dealt with by the audio adjustment.
8. Menu-related specifications
• A short press of the CLK key initiates the Menu mode.
• Pressing the DNPP/SBF key on the remote initiates the
Menu mode.
• Continuous holding of a remote control key is inhibited.
• Calendar adjustment, calendar display switching and cal-
endar memo are eliminated from the targets of continu-
ous key holding. (FL model).
• In the color adjustment mode, pressing the Preset 1 key
sets Red, 2 sets Blue, 3 sets Green and 4 sets Green.
(VLCD model)
• Contrast is adjusted in 3 steps of 0/5/10 and the default
is 5. (VLCD/LCD model)
• Brightness is adjusted in 3 steps of 0/5/10 and the default
is 10. (Normal FL model)
9. Backup current measurement
• When the unit is reset while Acc is OFF (i.e. by turning
Back-Up ON), the MUTE terminal goes OFF in 2 sec-
onds in place of 15 second. (The panel, CD mechanism
and TAPE mechanism are not activated at this time.)

10. Special display when the display is All ON
Pressing the Preset keys while the power is All OFF dis-
plays the following information.
7Security-related information
• Forced Power ON mode (All models)
Even when the security (Mask key) is approved, reset-
ting the unit while holding the ATT and Preset 4 keys
makes it possible to turn the power ON for 30 minutes.
After 30 minutes have elapsed, it is not possible to return
to the previous condition unless the unit is reset again.
• Method of registration of the security code after
EEPROM (Tuner Unit Ass'y) replacement (Code
security model)
1. Enter the test mode. (See 1 How to enter the test
mode)
2. Press the CLK key to enter the security registration
mode.
3. Enter the code using the Preset 1/2/3/4 keys.
Example: To enter "3510"
• Press the Preset 1 key 4 times.
• Press the Preset 2 key 6 times.
• Press the Preset 3 key twice.
• Press the Preset 4 key once.
4. Press and hold the DISP key for 3 seconds until
"APPROVED" is displayed.
5. Exit from the test mode. (See 2 How to exit from the
test mode)
(Note) All Clear is not applicable to the security code of
this model.
• Simplified method of clearing the security code
(K Type only)
1. While the code entry is requested, press and hold the
VOL UP key for 3 seconds while holding the DISP key
pressed.(This should turn ---- off.)
2. Enter "KCAR" from the remote. (Same way as the 00
model)
Press the 5 key on the remote twice, then press the
Track Up key. (This enters "K")
Press the 2 key on the remote 3 times, then press the
Track Up key. (This enters "C")
Press the 2 key on the remote once, then press the
Track Up key. (This enters "A")
Press the 7 key on the remote twice, then press the
Track Up key. (This enters "R")
3. The security code is cleared and the unit enters the All
OFF mode.
4. If you commit a mistake in the code entry, the unit
enters the code request mode again.
11. Other specifications
• Automatic panel closing when a tape/CD is inserted is
inhibited. (M&T model)
• Panel operation by turning power OFF/ON is inhibited.
(M&T model)
• Pressing the ATT key opens or closes the panel. (M&T
model)
• Messages such as "CODE OFF" are not displayed when
power is turned ON.
• Pressing the TI (AUTO) key during changer operation
turns 2zone ON. 2zone can be turned OFF by pressing
the TI (AUTO) key again. The P/S dot lights while 2zone
is ON.
• Pressing and holding the CLK key for a second in the All
OFF status the Mask Key (security) write mode.

KRC-709,779R/RY,889

TEST MODE
• Method of writing the Mask key while the EEP-
ROM is in the initial status
1. Enter the test mode. (See 1 How to enter the test mode)
2. Press the CLK key to enter the Mask key registration
mode. "TRANSMIT1" should be displayed now. The
display at this time should show "< >" in place of "[ ]".
3. Point the Mask key remote toward the light sensor, and
press and hold its key for more than 0.5 second.
4. When "TRANSMIT2" is displayed, press and hold the
key on the Mask key remote for more than 0.5 second
again. The first and second counter codes are not com-
pared at this time.
5. When "APPROVED" is displayed, the write operation is
complete. Now the demonstration mode is initiated and
the test mode is terminated.
(Note) In the same way as previous models, if 30 min-
utes have elapsed with no code written, an error occurs
and the power is turned OFF.
• Method of initializing the Mask key (How to reset
the unit from the Mask key approved condition
to the factory condition)
1. Enter the test mode. (See 1How to enter the test
mode)
2. "TRANSMIT1" is displayed and the Mask key entry
request mode is initiated.
The display at this time should show "✽✽" in place of "[ ]".
3. Press and hold the key on the Master key remote for
more than 3 seconds.
4. When "TRANSMIT2" is displayed, press and hold the
key on the Master key remote for more than 3 seconds.
5. When "APPROVED" is displayed, the Mask key is
cleared, the demonstration mode is initiated, the test
mode is terminated and the unit returns to the factory
condition.
• Method of clearing all Mask key-related data
1. Enter the test mode. (See 1How to enter the test
mode)
2. Press the CLK key to enter the Mask key registration
mode. "TRANSMIT1" should be displayed now.
3. Point the Master key remote toward the light sensor,
and press and hold its key for more than 3 seconds
(until the level display shows the full condition).
4. When "TRANSMIT2" is displayed, hold the key on the
Mask key remote for more than 3 seconds again.
If "TRANSMIT1" is displayed in place of "TRANSMIT2",
restart the procedure from step 3.
5. When "APPROVED" is displayed, all security data is
cleared and the unit returns to the condition before
Mask key writing with the EEPROM in the initial status.
