Denso BHT-825QW User Manual page 11

To System Designers:
• When introducing BHTs in those systems that could affect human lives (e.g., medicines management
system), develop applications carefully through redundancy and safety design which avoids the
feasibility of affecting human lives even if a data error occurs.
Handling the battery cartridge
• Never charge a wet or damp rechargeable battery cartridge.
Doing so could cause the batteries to break, generate heat, rupture or burn.
Handling the BHT
• If smoke, abnormal odors or noises come from the BHT, immediately turn off the power, pull out the
battery cartridge, and contact your nearest dealer.
Failure to do so could cause smoke or fire.
• If foreign material or water gets into the BHT, immediately turn off the power, pull out the battery
cartridge, and contact your nearest dealer.
Failure to do so could cause smoke or fire.
• If you drop the BHT so as to damage its housing, immediately turn off the power, pull out the battery
cartridge, and contact your nearest dealer.
Failure to do so could cause smoke or fire.
• Do not use batteries or power sources other than the specified ones; doing so could generate heat or
cause malfunction.
• When using the hand strap or neck strap, exercise due care to avoid getting them caught in other
objects or entangled in rotating machinery.
Failure to do so could result in accident or injury.
• Never disassemble or modify the BHT; doing so could result in an accident such as break or fire.
Never dis-
assemble
• Never put the BHT in places where there are excessively high temperatures, such as inside closed-up
automobiles, or in places exposed to direct sunlight.
Doing so could affect the housing or parts, resulting in a fire.
• Avoid using the BHT in extremely humid or dusty areas, or where there are drastic temperature
changes.
Moisture or dust will get into the BHT, resulting in malfunction, fire or electrical shock.
• In environments where static electricity can build into significant charges (e.g., if you wipe off the plastic
plate with a dry cloth), do not operate the BHT. Doing so will result in malfunction or machine failure.
• Do not place magnetic cards or the like near the BHT speaker. Doing so may result in the loss of
magnetic data from cash cards, credit cards, etc.
• Do not place your ear near the speaker when tones are being emitted. Doing so may result in hearing
loss.
• Do not apply excessive force when inserting or removing the rechargeable battery cartridge. Doing so
will result in damage.
