BHT-904B/BHT-914B
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 BHT
Incorrect handling of the BHT could cause not only incorrect operation, but also generation of heat and smoke from
the BHT, and malfunction.
Please read the following items prior to use.
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.
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.
 Do not place magnetic cards such as cash cards, credit cards, etc., near the BHT speaker. Doing so
may result in the loss of magnetic data.
 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 loading or unloading the battery. Doing so will result in damage to

the device.
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 drop the BHT on the floor or apply strong shock to it. Doing so could cause malfunction of the

BHT.
Do not use batteries other than that specified by DENSO WAVE.
