MICROCOMPUTER’S TERMINAL DESCRIPTION

r Antenna Detection Method (1)SSM internal circuit is used to detect antenna connection. Sub µ-

com makes judgment by a notification from SSP.

(2)Current detection for excess current protection uses the same

method as KTC-SR902. It is necessary to change the threshold set by software, as resistance value for detection has been changed. When the value is “28” or higher, it is determined that excess current is detected → DC/DC is stopped.

(3)Antenna power supply produced in DC/DC is 7.2V.

TEST MODE

●How to enter the test mode

Reset while pressing both Preset q key and Preset e key at the same time.

●How to clear the test mode

• Ez700SR/Ez900HDS Model Reset while pressing down Preset y key. This should be done with panel-not-installed and other modes ON. (Reset, ACC OFF, power OFF, and momentary power drown do not clear the test mode.)

• Ez500 Model Reset, ACC OFF, power OFF, panel-not-installed and other modes ON. (Note : Momentary power down does not clear the test mode.)

●Initial conditions of the test mode

• Source is STANDBY.

•Displays are all lighted up.

•Volume is -10dB (displayed as 30).

• LOUD is OFF.

• CRSC is to be turned OFF, regardless of whether there is switching function or not.

• SYSTEM Q is FLAT.

• BEEP is sounded with a short-push at all times.

•AUX is ON.(This is only the models with AUX.)

• SYSTEM Q on the menu is OFF.

• (The initial value of the variable model is white.)

●Special displays when set to TUNER (Ez500 Model

only)

When in TUNER mode, if the following messages were displayed, there are abnormalities in the front end, etc.

• “TNE2P” : EEPROM is still with the initial value (unspecified

value), as the F/E being shipped without going through the adjustment process.

• “TNCOM” : Communication with the F/E is not possible.

●CD receiver test mode specification

• At the time of the reset start, forced CD eject is prohibited. If

reset is effected with the CD in the unit, the CD would not be recognized.

• By the use of the track-up key, jumps are made to tracks in

the following order.

No. 9 → No. 15 → No. 10 → No. 11 → No. 12 → No. 13 → No. 22 → No. 14 → No. 9 (Returns to the starting point)

• By the use of the track-down key, it is possible to go down

one track from the current one.

• If the total number of tracks of an MP3 disc is less than 9,

the first track will be the first track to be played.

• If the media is CD, pressing Preset q key would effect a jump to No. 28.

• If the media is CD, pressing Preset w key would effect a jump to No. 14.

• If the media is CD, pressing Preset y key would effect a jump to No. 15. (Models with DC error detection function (Ez700SR, Ez900HDS)

●Audio-related matters

• By using a short-push on the A UD ke y, it is possible to enter the Audio Adjust Mode.

• By pressing ∗ key on the remote controller, it is possible to enter the Audio Adjust Mode.

• Long-push on the remote controller is prohibited. Shortpushes are to be used for operation.

• The initial items are faders.

• Using track up/down key, the fader is to be adjusted to the following three steps : R15 ⇔ 0 ⇔ F15. (Initial value : 0)

• Using track up/down key, the SW Level is to be adjusted to the following three steps :-15 ⇔ 0 ⇔ +15. (Initial value : 0)

•Using track rack up/down key, Bass/Middle/Treble is to be adjusted to the following three steps :-8 ⇔ 0 ⇔ +8. (Initial value : 0)

*Bass f/Bass Q/Bass EXT/Middle f/Middle Q/Treble f do not

appear in the Audio Adjustment.

• Using track up/down key, balance is to be adjusted to the following three steps : L15 ⇔ 0 ⇔ R15. (Initial value : 0)

• Using track up/down key, HPF is to be adjusted to the following 2 steps : THRU ⇔ 170Hz (or 200Hz. (Initial value : THRU) (Ez500)

• Using tr ack up/do wn k e y, HPF Front is to be adjusted to the following 2 steps : THRU ⇔ 170Hz. (Initial value : THRU) (Ez700SR, Ez900HDS)

• Using tr ac k up/do wn k e y, HPF Rear is to be adjusted to the following 2 steps : THRU ⇔ 200Hz. (Initial value: THRU) (Ez700SR, Ez900HDS)

• Using track rack up/down key, LPF is to be adjusted to the following 2 steps : THRU ⇔ 120Hz. (Initial value : THRU) (In the 2 Pre-out models, by using long-push on ATT, it is possible to switch Pre-out NF/REAR.)

●MENU-related items

• Using a short-push on the PALY/PAUSE key, it is possible to enter the MENU.

• Using the DNPP key on the remote controller, it is possible to enter the MENU.

• Using a long-press on the remote controller is prohibited. Short-pushes are to be used for operation.

•Using the track up/down key, contrast adjustment is to be

TEST MODE

conducted into the following 3 steps : 0 ⇔ 5 ⇔ 10. (Initial value : 7)

● Back up current measurement

When reset with ACC OFF (or with backup is ON) MUTE terminal goes OFF after 2 seconds, instead of 15 seconds as is normally the case. (At that moment, the CD mechanism is not operating.)

●

Special display when all indicators are lighted up

When the preset key is pressed with all indicators lighted up in All OFF mode, the following will be displayed.

● Others

• When q key is pressed, only during internal AUX, 2-ZONE ON/OFF is effected. When ON, P/S dot is turned ON all the time.

• When turning power ON, “CODE OFF/ON” will not be displayed.

• When booted up in Test Mode, normally 10 seconds LINE MUTE prohibition time is shortened to 1 second.

• In the Test Mode, security code should not be written with security jigs. (*1)

• In the Test Mode, serial number should not be written with serial number writing jigs. (*1)

• In the Test Mode, even if OEM Display is not connected, “OEM Display Out” output is not stopped. (*1) Since this mode clears Test Mode by resetting, it is not necessary to have it.

● Frequency span switching (K/M Type)

Reset while pressing both q and t keys.

● OEM compatible setting (Electronic volume des-

tination setting) (Ez500 only)

The models installed with S03F/E can cope with OEM models by using the 2-pin on the microcomputer. The following is the setting method.

●Security

•Forced power ON mode It is possible to make the power come on for 30 minutes only, even if the security is set (for both the simplified security and security codes.). This is achieved by pressing Q and r keys at the same time. Recoveries can be made only by resetting after the elapse of 30 minutes. (Note : Use of the above mode does not clear the security code. It’s purpose is to have the power come on temporarily.)

•How to clear the simplified security code (K-type only)

1.When it is requested to enter the code, while pressing

AUTO key, use long-push on the Track up key for 3 seconds. (This makes – – – – disappear.)

2.Using the remote controller, input “KCAR”.
