SERVICING NOTICES ON CHECKING

1. KEEP THE NOTICESAs for the places which need special attentions, they areindicated with the labels or seals on the cabinet, chassisand parts. Make sure to keep the indications and noticesin the operation manual.

2. USE THE DESIGNATED PARTS

The parts in this equipment have the specificcharacters of incombustibility and withstand voltage forsafety. Therefore, the part which is replaced should beused the part which has the same character.Especially as to the important parts for safety which isindicated in the circuit diagram or the table of parts asa mark, the designated parts must be used.

3. PUT PARTS AND WIRES IN THE ORIGINALPOSITION AFTER ASSEMBLING OR WIRING

There are parts which use the insulation material suchas a tube or tape for safety, or which are assembled inthe condition that these do not contact with the printedboard. The inside wiring is designed not to get closer tothe pyrogenic parts and high voltage parts. Therefore,put these parts in the original positions.

PERFORM A SAFETY CHECK AFTERSERVICING

4.

Confirm that the screws, parts and wiring which wereremoved in order to service are put in the originalpositions, or whether there are the portions which aredeteriorated around the serviced places serviced or not.Check the insulation between the antenna terminal orexternal metal and the AC cord plug blades. And be surethe safety of that.

IMPORTANT NOTICE

The remote control for this model can be selected the Custom code 1 and Custom code 2.• How to selection;

Custom code 1 : P

Custom code 2 :

Press the Power key and 1 key on the remote controlsimultaneously for more than 2 seconds.Press the Power key and 2 key on the remote controlsimultaneously for more than 2 seconds.

The Custom code 1 is only available for the VCR unit but the Custom code 2.When selected the Custom code 2 by mistake, just remove the batteries from the remotecontrol for the moment or select the Custom code 1 as described above.

PREVENTIVE CHECKS AND SERVICE INTERVALS

CLEANINGNOTE

After cleaning the heads with isopropyl alcohol, do notrun a tape until the heads dry completely. If the headsare not completely dry and alcohol gets on the tape,damage may occur.

1. AUDIO CONTROL HEAD

Wrap a piece of chamois around your finger. Dip it inisopropyl alcohol and clean the audio control head bywiping it horizontally. Clean the full erase head in thesame manner. (Refer to the figure below.)

Audio Control Head

2. TAPE RUNNING SYSTEM

When cleaning the tape transport system, use thegauze moistened with isopropyl alcohol.

3. CYLINDER

Wrap a piece of chamois around your finger. Dip it inisopropyl alcohol. Hold it to the cylinder head softly.Turn the cylinder head counterclockwise to clean it (inthe direction of the arrow). (Refer to the figure below.)

NOTE FOR THE REPLACING OF MEMORY IC

If a service repair is undertaken where it has been required to change the MEMORY IC, the following steps should be taken toensure correct data settings while making reference to TABLE 1.

3.

4.5.6.7.8.The unit will now have the correct DATA for the new MEMORY IC.

ADDRESS DATA

1.2.

Turn on the POWER and press both FF key and CH UP key on the set for more than 2 seconds.ADDRESS and DATA should appear as FIG 1.

Fig. 1

ADDRESS is now selected and should "blink". Using the SET + or - keys on the remote, step through the ADDRESS untilrequired ADDRESS to be changed is reached.Press ENTER to select DATA. When DATA is selected, it will "blink".Again, step through the DATA using SET + or - until required DATA value has been selected.Pressing ENTER will take you back to ADDRESS for further selection if necessary.Repeat steps 3 to 6 until all data has been checked.When satisfied correct DATA has been entered, turn POWER off (return to STANDBY MODE) to finish DATA input.

•

•

Place an object which weighs between 450g~500g onthe Cassette Tape to keep it steady when you want tomake the tape run without the Cassette Holder. (Do notplace an object which weighs over 500g.)When you activate the deck without the CassetteHolder, short circuit between TP1001 and TP1002.(Refer to ELECTRICAL ADJUSTMENT PARTSLOCATION GUIDE) In this condition the BOT/EOT/ReelSensor will not function.
