PREPARATION
INSTALLING BATTERIES
Your System 931 requires four AAA batteries (not sup-
plied) for power. For the longest operation and best
performance, we recommend alkaline batteries, avail-
able at your local RadioShack store.
Cautions:
• Always use fresh batteries of the required size
and recommended type.
• Do not mix old and new batteries, different types
of batteries (standard, alkaline, or rechargeable),
or rechargeable batteries of different capacities.
Follow these steps to install batteries.
Notes:
• When you replace the batteries, do not press any
button on the system after you remove the old
batteries. Doing so could erase all stored infor-
mation.
