Proper Care of the BHT
Make sure to turn OFF the BHT before cleaning.
● Terminal dirt on the BHT, charger and battery cartridge
Periodically wipe any dirt from the terminals of the BHT, charger and battery cartridge with a cotton
swab or similar soft object. The terminal should be treated with the utmost care so as not to be
scratched or bent during a cleaning.
Never use organic solvents such as benzene or alcohol, as this may cause the coated surface to come
off.
● Housing dirt
Wipe any dirt from the housing with a dry, soft cloth.
If excessively dirty, wipe with a soft cloth that has been soaked in soapy water (always use neutral
detergent) and wrung out thoroughly.
Never use organic solvents such as benzene or alcohol, as this may cause the housing to be marred or
paint to peel off.
● LCD screen dirt
Never rub or strike the LCD screen with anything hard, as this may result in scratches on the screen or
breakage.
● Keypad dirt
When cleaning the keypad, do not scrub the surface too hard or pull on the keys, as this may break the
keys.
● Code reading window dirt
Any dirt or dust adhering to the clear plate of the code reading window will adversely affect reading
performance.
When using in dusty areas, perform periodic inspections to check whether any dust has accumulated
on the clear plate of the code reading window, and if so, first blow the dust away with an airbrush, and
then gently wipe the plate with a cotton swab or similar soft object.
If sand or hard particles have accumulated, rubbing the plate will result in scratches. Blow the particles
away with an airbrush or wipe with a soft brush.
