1.8 Proper Care of the BHT
Make sure to turn OFF the BHT before cleaning.
Cleaning the BHT and charging contacts
To keep clean BHT and charging contacts, periodically wipe them clean with a cotton swab and
the like. Be sure not to scratch or deform the contacts while cleaning.
Never use organic solvents such as thinner or alcohol, as this may cause plating of the contacts to
be peeled off.
Cleaning the Housing
To keep the appearance of the BHT at its best, wipe it clean with a dry, soft cloth.
To best clean the BHT, wipe it clean with a cloth slightly dampened with diluted neutral detergent
and dry with a soft, dry cloth.
Never use organic solvents such as thinner or alcohol, as this may cause the housing to be
marred or paint to be peeled off.
Cleaning the LCD screen
Never rub or hit the LCD screen with anything hard, as this may result in scratches on the screen
or breakage.
Cleaning the Reading window
Keep clean reading window; otherwise, reading performance may be adversely affected.
When using in dusty areas, check the clear plate of the reading window for the accumulation of the
dust, on a regular basis. To keep clean device at its best, blow dust away with an airbrush and
wipe it clean with a cotton swab and the like.
Hard particles such as sand can cause abrasive wear on the plate. Blow them away with an airbrush
or brush them away with a soft brush.
Important Notice of Disinfection and Maintenance for DENSO WAVE AUTO-ID Products.
As described in the care and maintenance of the Operator’s Guide* contained in the package of
regular AUTO-ID products, the usage of thinner and alcohol for cleaning is prohibited.
In consideration of the currently widespread novel coronavirus infection, DENSO WAVE performed
the wiping test under its own test standards using 70% ethanol or 10 ppm to 80 ppm hypochlorous
acid water in expectation of a certain disinfection effect. As a result, we visually confirmed that there is
no remarkable discoloration and color fading on the surface of the housing. Before using the solutions
described below, please read and understand the following descriptions.
