Notes in each part
BHT terminal,
charger terminal dirt
Do not touch the BHT or the communication unit terminals by hand or stain them.
Doing so could result in malfunction, a contact failure or prevent charging.
Periodically clean the terminals of the BHT or the communication unit. And when
they got dirty, wipe them away on each time.
Wipe any dirt on the charge terminals with a dry, soft cloth (such as a lens cloth) or
a cotton swab. But be careful not to damage the charge terminals when wiping
them.
Never use substances such as benzene, thinner and alcohol. Doing so can cause
plating on the charge terminals to be marred.
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 substances 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.
Barcode reading window dirt
Any dirt or dust adhering to the clear plate of the barcode 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 barcode 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.
6.4.2 Proper Care of the CU/CH
