Proper Care of the BHT

Wipe the BHT's charge terminals and battery cartridge terminals with a cotton swab
or the like periodically. Clean the BHT housing with a dry, soft cloth. Before cleaning,
be sure to turn the BHT off.
• Never use benzene, alcohol, or other
organic solvents. The housing may be
marred or the paint may come off.
• Never rub or strike the liquid crystal
display (LCD) with anything hard. The
LCD surface will be easily scratched or
broken.
• When cleaning the keypad, do not scrub
the surface too hard or pull on the keys.
Doing so may break the keys.
• If the BHT becomes smudged, wipe it with a soft cloth that has been moistened in
soapy water (always use neutral detergent) and wrung out thoroughly.
Dust or dirt accumulating on the clear plate of the reading window will affect reading
performance. If you use the BHT in dusty areas, therefore, periodically check the
clear plate of the reading window and clean it if dusty.
• To clean the plate, first blow the dust away with an air brush. Then wipe the plate
with a cotton swab or the similar soft one gently.
• If sand or hard particles have accumulated, never rub the plate; doing so will
scratch or damage it. Blow the particles away with an airbrush or a soft brush.
