The
AT Pro
is a rugged machine, designed for outdoor
use in all environments. However, as with all electronic
equipment, there are some simple ways to care for the
detector to maintain its high performance.
• Avoid extreme temperatures as much as possible, such
as storing the detector in an automobile trunk during the
summer or outdoors in sub-freezing weather.
• Keep the detector clean. Wipe the control housing with a
damp cloth when necessary.
• Disassemble the stem, and wipe it and the searchcoil clean
with a damp cloth.
• When storing for longer than one month, remove the
batteries from the detector.
• It is best to use quality alkaline batteries. When changing
batteries, be sure to replace with all new batteries for
optimum performance.
• Replace protective cover on the connector when not using
headphones.
