Option Card Problems

If you install an option card and get unexpected results, check the following questions:

1.Is the option card installed correctly?

2.Did you follow the setup and operation instructions in the option card manual?

3.Did you set any necessary jumpers or DIP switches on the option card? See your option card instructions.

4.If you added an external device, do you have the proper cable to connect the peripheral to the option card connector on the back panel?

5.Did you reset the DIP switches on the main unit to match your new system configuration? See “Setting the DIP Switches” in Chapter 1.

6.Did you perform any necessary post-installation setup procedures? See “Post-Installation Adjustments” in Chapter 4.

Memory Problems

If the computer does not save your system configuration settings and the correct date and time when it is off, the CMOS RAM backup battery may be disabled.

To enable the battery, follow the instructions in Chapter 4 to remove the main unit’s cover. Locate the battery just behind the front panel on the side with the Epson Equity II logo and find switch 4 near the battery connector on the main system board. Turn on this switch to enable the battery.

If the computer still does not save your settings while it is off, the battery may be low. To replace it, see the next section.

The Battery Is Low

The Equity II’s CMOS RAM backup battery lasts at least 11/2 years. When MS-DOS loads, it checks the battery. If the battery is getting low, this message displays:
