To System Designers:
z 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 BHT
z Never put the BHT into a microwave oven or high-pressure container.
Doing so could cause the BHT to break, generate heat, rupture or burn.
z 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.
z 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.
z 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.
z If you drop the BHT so as to damage its housing, immediately turn off the power, pull out the battery
cartridge.
Failure to do so could cause smoke or fire.
z Do not use batteries or power sources other than the specified ones.
Doing so could generate heat or cause malfunction.
z Never disassemble or modify the BHT; doing so could result in an accident such as break or fire.
z Do not insert foreign materials in the BHT.
z 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.
z If the LCD breaks, the liquid may leak from the LCD under some conditions. If so, do not attempt to
swallow, inhale or touch it.
z Never stare into the reading window.
z Never point the reading window at someone’s eye.
Handling the BHT
z 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.
z Do not use the BHT in the vicinity of wireless devices such as personal radios and ham radios. This
could cause malfunction of the BHT.
z Do not place magnetic cards or the like near the BHT speaker/beeper.
Doing so may result in the loss of magnetic data from cash cards, credit cards, etc.
z Do not place your ear near the speaker/beeper when tones are being emitted.
Doing so may result in hearing loss.
z Do not apply excessive force when inserting or removing the rechargeable battery cartridge.
