Concerning

Series 6000 and 7000 English Mark Dart Games

January 18, 1990

WARNING---DISCONNECT ELECTRICAL POWER BEFORE ATTEMPTING

SERVICE

We are recommending that the main fuse FS3 be upgraded from a 1.5 Amp

Slow Blow to a 2.0 Amp Slow Blow. Due to slight variances in components,

some games draw more current than others.

When these games are

connected to high line voltage, the current draw gets even higher, close to the

rating of the 1.5 Amp fuse. After a period of time, the fuse will blow, even

though the rating may not have been exceeded.

Since all of the components in the power supply are rated at a minimum of 2

Amps, no damage will occur as a result of this change. Do not exceed the 2.0

Amp rating, however. If the 2.0 Amp fuse blows, there is a definite problem

in the power supply, indicating it needs to be serviced by a qualified

technician.

If there are any problems regarding this or any other service problem, please

call ARACHNID, INC. at 800-435-83 19 or in Illinois at 8 15-654-02 12.
