Replacing the Battery
Changes that you make to your PC2 settings are stored using a Lithium battery when the PC2 is
powered off. When it is time to replace your battery, the PC2 will display the message: ÒBattery
voltage is lowÓ for a few seconds after being powered up. If this happens, you should replace
the battery as soon as possible.
Before you Begin
YouÕll need the following items:
¥
one CR2032 battery which is a 3 volt Lithium coin cell that can be purchased from Radio
Shack and large drug stores.
¥
a #2 Phillips screwdriver
¥
a large table with a padded surface to prevent damage: foam or soft cloth
¥
a pen cap or plastic knife
Replacing the battery may erase the programs and setups that you have created, so back them
up using a MIDI SysEx dump as described on page 4-4. When you are Þnished, turn off the
power and remove all cables from your PC2 including the power adapter.
Opening your PC2
1. Place your PC2 with the keyboard and front panel down on the padding with the rear
panel jacks facing you.
2. You will see a ßat panel about 15 inches long and 4 inches wide in the bottom of the PC2.
Use the screwdriver to remove the 7 screws that fasten the option panel.
3. Remove the panel by sliding the panel a couple of inches away from you and lifting it out
of the opening.
Installing the Battery
1. If the PC2 has any Sound ROM options installed, remove each of them by pushing the
metal tabs on each end of the SIMM socket outwards at the same time, tilting the option
board to a vertical position, and removing. Note the positions of the option boards, so you
can replace them properly.
2. Insert your Þngernail, a plastic knife, or a pen cap in one of the slots on the top of the
batteryÕs retaining clip and gently pry the battery loose from the retaining clip, as shown
in Figure 5-1.
