You can power the instrument with either mains power or batteries, depending on where you’re
using it. If you use mains power while batteries are installed in the instrument, the AC adapter takes
precedence.
When you are unable to operate the instrument using mains power, you can power it with six LR20
alkaline batteries instead. The batteries will also serve as a backup power source in the event of a
power outage when using mains power.

Estimated operating times
• PR8111 (1-pen model): Approx. 50 hours
• PR8112 (2-pen model): Approx. 25 hours
When using the PR8112 (2-pen model) with just one pen, you can set the CH2 POWER switch on the
rear of the instrument to OFF to realize similar operating times as for the PR8111 (1-pen model).(p. 26)
Before installing batteries into the instrument, be sure to read "Using the Batteries" (p. 7).

Reattach the battery cover and tighten it
securely in place with the screws
removed in step (2) above.
The battery cover is held in place by M3-size screws.
To ensure safe operation, affix the battery cover with
screws. Avoid mixing new and old batteries or differ-
ent types of batteries. Note the positive and negative
poles and exercise care not to install the batteries
backwards. Doing so may result in degraded perfor-
mance or cause the batteries to leak.
