TEST MODE

1. Circuit Check Mode

Set to the reception frequency that the circuit 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, L W). Set to a desir ed band before setting the test mode.

1. Turn OFF the power.

2. While pressing 4 and AUTO-BETICAL SELECT together, turn ON ! .

• The items in the following table will be checked automatically in order every 2 seconds.

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 ! .

3. While continuously pressing 1 and AUTO-BETICAL SELECT together, check the following.

Microcomputer version indication (1 sec) t All light up “7F” t Dot area only “60” t Dot area only “7E”

Indication test pattern

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 : 25

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.

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.

3. Entering the Factory Preset (In case perform just to write memory of the Factory Preset.)

1. Turn OFF the power.

2. While pressing 3 and AUTO-BETICAL SELECT together, turn ON ! .

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 ! .

3. When “All clear” is indicated on the fluorescent display tube, it means that “Forced Reset” has been completed.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

For schematic diagrams.

Note:

• All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

• 2 : nonflammable resistor.

• C : panel designation.

Note: The components identified by mark 0 or dotted line

with mark 0 are critical for safety. Replace only with part number specified.

• U : B+ Line.

• V : B– Line.

• H : adjustment for repair.

• Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : FM

: Can not be measured.

W or less unless otherwise

WAVEFORMS

• Voltages are taken with a V OM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

• Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.

• Circled numbers refer to waveforms.

• Signal path. F : FM

For printed wiring boards.

Note:

• X : parts extracted from the component side.

• x : parts mounted on the conductor side.
