Doing so could cause the batteries to break, generate heat, rupture or burn. • Never charge the lithium-ion battery cartridge where any inflammable gases may be emitted; doing so could cause fire. Handling the BHT • The BHT-7000 uses a laser light for indicating the scanning range. The intensity of the laser light might be too low to inflict bodily injury. However, do not look into the laser beam. The BHT-7000 complies with Laser Safety Standard, Class II of 21 CFR Chapter 1, Subchapter J. The BHT-7000 does not mount beam attenuator and laser radiation emission indicator required by this standard. Instead, the software- controlled Magic keys (see Section 2.3 “Components and Functions”) function as them because the laser light is not enabled without the Magic keys pressed. Never put me into fire! Do not short- circuit me! Undedicated • Only use the dedicated charger (CU7000, C-700, or C-750) for charging the battery cartridge.
