To System Designers
 When introducing BHTs in those systems that could affect human lives, develop applications
carefully through redundancy and safety design which avoids the feasibility of affecting human lives
even if a data error occurs.
CAUTION
Handling the BHT
Incorrect handling of the BHT could cause generation of heat and smoke from the BHT, and
malfunction. Be sure to observe the following to use the device correctly.
 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.
 Keep your ears away from the speaker when a loud sound comes out of it. Failure to do so could
lead to hearing difficulty.
 Do not operate the BHT in environments where static electricity can build into significant charges.
Doing so could result in malfunction or mechanical failure.
 Avoid dropping the battery cartridge or letting it undergo any strong shock or impact. Doing so
could result in malfunction or mechanical failure.
 Do not use the BHT near a wireless transmitter such as a ham radio. Doing so could result in
malfunction or mechanical failure.
 Do not touch BHT with oily hands or gloves containing oil such as machine oil and grease. Doing
so may cause the deformation and discoloration of a device.
 This product incorporates connectors for microSD card and SIM cards. Do not insert anything other
than these cards. Do not insert a card inversely, diagonally and with twisted. If a card is inserted
forcibly, this could damage a card or a connector.
 Do not attach a wet BHT or rechargeable battery cartridge to CU.
 Do not use excessive force when inserting or removing the battery cartridge. Doing so could result
in malfunction or mechanical failure.
 Keep magnetic cards such as a cash card or a credit card away from the BHT. Failure to do so
could cause loss of magnetic data.
 Use of controls or adjustments or performance of procedures other than those specified herein may
result in hazardous radiation exposure.
 L'utilisation de commandes ou de réglages ou l'exécution de procédures autres que celles
spécifiées ici peuvent entraîner une exposition à des radiations dangereuses.
