Proper Care of the BHT
Clean the housing and the rechargeable battery cartridge terminals 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, and do not
pull on the keys. Doing so may break
the keys or cause the keypad to dislo-
cate.
• If the BHT becomes smudged, moisten a soft cloth with neutral detergent
and wring it out thoroughly. Wipe the BHT with the cloth and then go
over it again with a dry cloth.
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, periodi-
cally 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 air brush or a
soft brush.
