6.4.2. REPLACEMENT PROCEDURE
NOTE:
This work should be finished within 30 minutes so that the RAM data would not be lost as
running out of current from the Back-up Capacitor C7752.
1. Remove the Top Panel and Mechanism unit with Main C.B.A by
referring to the Disassembling Procedure.
2. Unsolder the Lithium Battery: B7751 and then replace it with a
new one (See Fig. B1).
NOTE:
The lithium battery is a critical component.
It must never be subjected to excessive heat or discharge.
It must therefore only be fitted in equipment designed specifically for its use.
Replacement batteries must be of the same type and manufacture.
They must be fitted in the same manner and location as the original battery, with the correct
polarity contacts observed.
Do not attempt to re-charge the battery or re-use it for any other purpose.
It should be disposed of in waste products destined for burial rather than incineration.
