Denso BHT-300B User Manual page 12

Proper Care of the BHT and CU
Clean 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
and unplug the AC adapter of the CU.
• 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.
Doing so may break the keys.
• If the BHT or CU becomes smudged, moisten a soft cloth with neutral detergent and wring it out
thoroughly. Wipe the BHT or CU with the cloth and then go over it again with a dry cloth.
Dust or dirt accumulating on the clear plate of the bar-code reading window will affect reading
performance. If you use the BHT in dusty areas, therefore, periodically check the clear plate of the
bar-code reading window and clean it if dusty.
• To clean the plate, first blow the dust away with an airbrush. 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.
