Radio Shack TRS-80 PC-3 User Manual

BATTERY REPLACEMENT FOR THE PC-3
The PC-3 Pocket Computer operates on the lithium battery alone. When connected to the PC-3 Printer/Cassette Interface, the
PC-3 can also be supplied from the PC-3 Printer/Cassette Interface if it has enough power voltage and the lithium battery power
decrease. This minimizes the power consumption of the lithium battery.
When replacing the batteries, these precautionary instructions will eliminate many problems:
• Always replace
both of the batteries at the same time.
• Do
not mix a new battery with a used battery.
• Use only: Lithium battery (type CR-2032) x 2
INSTALLING THE BATTERIES
The display is dim and difficult to see when viewed from the front, even after turning the contrast control on the right of the
computer counterclockwise as far as it goes. This indicates that the battery power is depleted. In this case, replace the battery
promptly. (Using the optional PC-3 Printer/Cassette Interface peripheral equipment, record programs and data on tape in advance.)
