Is the option card installed correctly?
Did you follow the setup and operation instructions in the option
card manual?
Did you set any necessary jumpers or DIP switches on the option
card? See your option card instructions.
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?
Did you reset the DIP switches on the main unit to match your new
system configuration? See “Setting the DIP Switches” in Chapter
1.
Did you perform any necessary post-installation setup procedures?
See “Post-Installation Adjustments” in Chapter

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 1 1/2 years.
When MS-DOS loads, it checks the battery. If the battery is getting low,
this message displays:
