External Cache Problems
If you added extra cache memory to your system by having
cache DIP chips installed, and that memory is not operating
properly, check the following:
1. If the cache memory amount displayed by the power-on
diagnostics program is incorrect, your Authorized Epson
Servicer may not have installed the cache correctly. Call
your servicer to describe the problem.
2. Did the servicer set jumpers J5 through J9 to indicate the new
amount of cache? Check the jumpers to see if they are set
correctly. See “Changing the Jumper and DIP Switch
Settings” in Chapter 4 for instructions.
3. If you still have trouble with your external cache, write down
any error messages that appear and contact the Epson
Connection for assistance.
Battery Problems
The battery in your computer is a 3.6 volt, lithium battery. It
should last from three to five years before you need to replace
it. When the batterys life has expired, you may see one of the
following error messages:
CMOS battery state low
CMOS system option
Purchase a new battery (available from Epson Accessories) and
follow the instructions in Chapter 4 to install it, or ask your
Authorized Epson Servicer to install it for you.
