Before servicing,unplug the power cord to prevent an electric shock.

When replacing parts,use only manufacturer’s recommended components for safety.Check the、condition of the power cord. RepIace if wear or damage ls evident.

After servicing,be sure to restore the Iead dress,insulation barriers,insulation papers,shields,etc.

Before retuming the serviced equlpment to the customer,be sure to make the fo”owing insulation resistancetest to prevent the customer from being exposed to a shock hazard.

●lNSUIATION RESISTANCE TEST1.Unplug the powercord and short the two prongs of the plug with ajumperwire.

2.Tum on the power switch.

3.Measure the resistance value with ohmmeter between the jumpered AC plug and each exposed metal cabinet

   part,such as screwheads antenna,control shafts,handle brackets,etc. Equipment with antenna terminals

   should read between3MΩand5。2MΩto a”exposed parts(Fig.A). Equipment without antenna terminals   should read approximately infinity to all exposed parts(Fig、B).

Note=Some exposed parts may be isolated from the chassis by design. These will read infinity.

For your safety,please read the fo”owing text care-

fu”y。

This appliance is supplied with a moulded three pin

mainsplugforyoursafetyandconvenience.A5-ampere fuse is fitted in this plug.

Should the fuse need to be replaced please ensure

that the replacement fuse has a rating of5-ampere

and that it is apProved by ASTA or BSl to BS1362.

Checkf・rtheASTAmark愈・rtheBSlmark甲・nthe body ofthe fuse,

If the plug contains a removable fuse cover you must

ensure that it is refitted when the fuse is replaced.

If you iose the fuse cover the plug must not be used

until a replacement cover is obtained。

A replacement fuse cover can be purchased fromyour local dealer.

The wire which is coloured BROWN must be con-

nected to the terminal in the plug which is marked with

theIetterLorcobured RED.

Under no circumstances should either of these wires

be connected to the earth terminal of the three pin

plug,marked with the Ietter E or the Earth Symbol、去.

■WRITING TO EEPROMThis unit is equipped with EEPROM memory that stores a variety of design data and performance data

such as playback galn,bias value,recording gain,recording equalization,etc.,which was programmed

at the factory.

This EEPROM memory is capable of being read and written to more than100,000times. To i”ustrate

this,if one ATC operation is performed every hour continuously every day for ten years,it worId stlII be

possible to successfu”y read and write with the EEPROM.

Data is actua“y written in this EEPROM onIy when ATC ls actuated or when power supply is tumed on or off.

Since it hardly breaks down,there wiII scarcely occur such a trouble as to require repIacement.
