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.
