SECTION 2 TEST MODE
1. Circuit Check Mode
Set to the reception frequency that the curcuit can STEREO RDS stations. (Set the input level to above 70 dB.) This enables circuit check to be performed in any of the reception modes-FM, AM (MW, LW). Set to a desired band before setting the test mode. 1. Turn OFF the power. 2. While pressing 4 and AUTO-BETICAL SELECT together, turn ON U . · The items in the following table will be checked automatically in order every 2 seconds. Display Items DISPLAY FM RDS AM (MW, LW) OK or NG OK or NG OK or NG OK or NG OK or NG OK or NG OK or NG NG IC251 NG, RV251 adjustments FE101, IC251 NG, or IF count buffer amp (Q251, Q401) NG IC221 NG, RV221 adjustments IC301 NG, RV301 adjustments IC801 NG

NOTE : The preset data will be erased when this test mode is used. Therefore, take down the data before setting this mode and preset the data again after completing operations in this mode.
2. Display Tube Check and KEY Check mode
1. Turn OFF the power. 2. While pressing 1 and AUTO-BETICAL SELECT together, turn ON U . 3. While continuously pressing 1 and AUTO-BETICAL SELECT together, check the following.
Microcomputer version indication (1 sec)
All light up "7F"

* The indication test pattern from 2 to 5 are indicated on only even grids. The display changes every 1 sec. 4. Release 1 and AUTO-BETICAL SELECT . The KEY CHECK mode will be set. 5. All key numbers will be displayed. Key Number : 27 6. Each time the key is pressed, the key number will be counted down. Each key will be counted only once, at the first time. 7. When all keys have been pressed, the process will end.

3. Entering the Factory Preset (In case perform just to write memory of the Factory Preset.)
NOTE : As contents of the Factory Preset will be written into memory after completing this check mode, delete contents of memory according to 4. Forced RESET. 1. Turn OFF the power. 2. While pressing 3 and AUTO-BETICAL SELECT together, turn ON U .
4. Forced RESET (Used to delete the contents of Factory Preset when it is written into the preset memory.)
Clears all the RAMs and sets the initial state 1. Turn OFF the power. 2. While pressing 5 and AUTO-BETICAL SELECT together, turn ON U . 3. When "All clear" is indicated on the display tube, it means that "Forced Reset" has been completed.

Adjust IFT253 for a minimum reading on the distortion meter. ................... MONO Distortion (THD) 4. Repeat the adjustments of 2 and 3 several times. Note : When replacing the ceramic filter, perform this alignment.
How to switch IF BAND : WIDE/NARROW and ANT ATT : ON/OFF
Method 1: 1. Set the reception mode to FM. 2. Push the MENU button and turn the TUNING/SELECT to indicate "Reception" on the fluorecent display tube, then press the ENTER button. 3. Rotate the TUNING/SELECT knob in the clokwise direction. (Proceeds onto the step 5 when rotated in the counterclokwise direction.) 4. Turn the TUNING/SELECT knob to indicate "ANT ATT : OFF" on the fluorescent display tube, then press the ENTERl button. 5. Turn the TUNING/SELECT knob to indicate "IF : NARROW" or "IF : WIDE" on the fluorescent display tube, then press the lENTER button. When the IF BAND : NARROW is set, "NARROW" is indicated on the fluorescent display tube. 6. Set WIDE after the operation. * When set to standby for inputs using the TUNING/SELECTl knob, "SELECT" is indicated on the fluorecent display tube. Method 2: After the test modes "2. Display Tube Check and KEY Check mode" or "3. Entering the Factory Preset", "IF : NARROW" and "IF : WIDE" are switched every time pressing RETURN button the IF BAND : NARROW is set "NARROW" is indicated on the fluorescent display tube. Likewise, the mode can be switched between "ANT ATT : ON" and "ANT ATT : OFF". When set to ANT ATT : ON, the fluorescent display tube indicates ANT ATT.

SECTION 6 ELECTRICAL PARTS LIST
· Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. -XX, -X mean standardized parts, so they may have some difference from the original one. Items marked "*" are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. CAPACITORS: uF: µF Remarks Ref.
