Using Batteries
You can use two AA batteries (not supplied) to power your Micro-37. We recommend alkaline batteries, such as RadioShack Cat. No. 23-552.
Cautions:
• Use only fresh batteries of the
required size and recommended type.
• Never leave dead or weak batteries in
the Micro-37. Batteries ca n leak c hemicals that can destroy electronic circuits.
• Do not mix old and new batteries, dif-
ferent types of batteries (standard,
alkaline, or rechargeable), or rechargeable batteries of different
capacities.
• Dispose of old batteries promptly; do
not bury or burn them.

Using AC Power
To power the Micro-37 from an AC outlet,
you need an AC adapter (not supplied),
such as Cat. No. 273-1654B.
Cautions:
• You must us e an AC ad apte r t hat s upplies 3 volts DC p ower and deli vers at
least 200 milliamps. The center tip of
the adapter barrel plug must be set to
positive, and the plug must properly fit
the Micro-37’s
mended AC adapter meets these
specifications. Using an AC adapter
that does not meet these specifications could damage the Micro-37, the
AC adapter, or the plug.
• Always connect the AC adapter to the
Micro-37 before you plug it into the AC
outlet, and unplug the adapter from
the AC outlet before you unplug it from
the Micro-37.
