TEST MODE

M&T-SRT 2001 Model Test Mode

1. How to enter the test mode• While holding the FM and Preset 6 keys, reset the unit.

2. How to exit from the test mode• While holding the Preset 6 key, reset the unit.• (Note) The test mode cannot be terminated by Acc OFF,

power OFF or momentary power down.

3. Initial status in the test mode• Sources: All OFF.• Display: All segments are lit.• Volume: -10 dB (displayed as 30)• Loudness: OFF• CRSC: OFF regardless of the presence of switching

function.• SYSTEM Q: Flat.• Blank Skip: OFF. (C/R model)• LED: White for no scanning. (VLCD model)

4. Special display in Tuner mode• When any of the following messages is displayed in

Tuner mode, the front end may be abnormal.• "TNE 2P NG": The EEPROM is set to the default (unsta-

ble values) because the F/E was shipped without passingthrough the adjustment process, etc.

• "TNCON NG": Communication with the F/E is not possi-ble.

5. Forced switching of K3I• Each press of the Preset 6 key in Tuner mode should

switch K3I from AUTO î Forced Wide î Forced Middleî Forced Narrow î AUTO. The initial status is AUTOand the display shows these modes as follows.

• AUTO : FMA• Forced Wide : FMW• Forced Middle : FMM• Forced Narrow : FMN

6. Test mode specifications of the CD receiver• Forced ejection is inhibited in the reset start operation.

When the unit is reset while a CD is loaded in it, the CDis not recognized by resetting.

• Each press of the Track Up key jumps to the followingtrack numbers.No. 9 î No. 15 î No. 10 î No. 11 î No. 12 î No. 13î No. 14 î No. 9 (The cycle restarts from here.)

• Each press of the Track Down key jumps to the previoustrack number to the track being played.

7. Audio-related specifications• A short press of the Q key initiates the audio adjustment

mode.• Pressing the key on the remote initiates the audio

adjustment mode.• Continuous holding of a remote control key is inhibited.• Bass, Middle and Treble are adjusted in 3 steps of

Min/Center/Max with the Track Up/Down keys.• Balance is adjusted in 3 steps of Left Max/Center/Right

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 keysets 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 defaultis 5. (VLCD/LCD model)

• Brightness is adjusted in 3 steps of 0/5/10 and the defaultis 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 mechanismand TAPE mechanism are not activated at this time.)

10. Special display when the display is All ONPressing the Preset keys while the power is All OFF dis-plays the following information.

7 Security-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 keysmakes it possible to turn the power ON for 30 minutes.After 30 minutes have elapsed, it is not possible to returnto the previous condition unless the unit is reset again.

• Method of registration of the security code afterEEPROM (Tuner Unit Ass'y) replacement (Codesecurity model)

1. Enter the test mode. (See 1 How to enter the testmode)

2. Press the CLK key to enter the security registrationmode.

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 thetest mode)(Note) All Clear is not applicable to the security code ofthis model.

• Simplified method of clearing the security code(K Type only)

1. While the code entry is requested, press and hold theVOL UP key for 3 seconds while holding the DISP keypressed.(This should turn ---- off.)

2. Enter "KCAR" from the remote. (Same way as the 00model)Press the 5 key on the remote twice, then press theTrack Up key. (This enters "K")Press the 2 key on the remote 3 times, then press theTrack Up key. (This enters "C")Press the 2 key on the remote once, then press theTrack Up key. (This enters "A")Press the 7 key on the remote twice, then press theTrack Up key. (This enters "R")

3. The security code is cleared and the unit enters the AllOFF mode.

4. If you commit a mistake in the code entry, the unitenters 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 pressingthe TI (AUTO) key again. The P/S dot lights while 2zoneis ON.

• Pressing and holding the CLK key for a second in the AllOFF status the Mask Key (security) write mode.

KRC-V879R/RY

10

TEST MODE• Method of writing the Mask key while the EEP-

ROM is in the initial status1. 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. Thedisplay at this time should show "< >" in place of "[ ]".

3. Point the Mask key remote toward the light sensor, andpress and hold its key for more than 0.5 second.

4. When "TRANSMIT2" is displayed, press and hold thekey on the Mask key remote for more than 0.5 secondagain. The first and second counter codes are not com-pared at this time.

5. When "APPROVED" is displayed, the write operation iscomplete. Now the demonstration mode is initiated andthe test mode is terminated.(Note) In the same way as previous models, if 30 min-utes have elapsed with no code written, an error occursand the power is turned OFF.

• Method of initializing the Mask key (How to resetthe unit from the Mask key approved conditionto the factory condition)

1. Enter the test mode. (See 1 How to enter the testmode)

2. "TRANSMIT1" is displayed and the Mask key entryrequest mode is initiated.The display at this time should show " " in place of "[ ]".

3. Press and hold the key on the Master key remote formore than 3 seconds.

4. When "TRANSMIT2" is displayed, press and hold thekey on the Master key remote for more than 3 seconds.

5. When "APPROVED" is displayed, the Mask key iscleared, the demonstration mode is initiated, the testmode is terminated and the unit returns to the factorycondition.

• Method of clearing all Mask key-related data1. 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.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 theMask 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 iscleared and the unit returns to the condition beforeMask key writing with the EEPROM in the initial status.
