v W ARNING Handling the battery cartridge • Never disassemble or heat the battery cartridge, nor put it into fire or water; doing so could cause battery-rupture or leakage of battery fluid, resulting in a fire or bodily injury. • Do not carry or store the battery car- tridge together with metallic ball-point pens, necklaces, coins, hairpins, et[...]

vi W ARNING • Do not look into the laser beam source through the reading window or point the reading window towards the eyes. The laser beam emitted through the reading window is harmful to the eyes. • Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation expo- sure. Hand[...]

vii CAUTION Basic handling tips • 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 hu- mid or dusty areas, or where there are drastic tempera[...]

viii CAUTION • If you drop the BHT so as to damage its hous- ing, immediately turn off the power, pull out the rechargeable battery cartridge or dry bat- tery cartridge, and contact your nearest dealer. Failure to do so could cause smoke or fire. • For those machines using the dry battery cartridge, do not mistake the plus and minus marks when [...]

ix CAUTION • Never cover or wrap up the CU or AC adapter in a cloth or blanket. Doing so could cause the unit to heat up inside, deforming its hous- ing, resulting in a fire. Always use the CU and AC adapter in a well-ventilated area. • Do not place the CU anyplace where it may be subjected to oily smoke or steam, e.g., near a cooking range or [...]

x ■ Proper Care of the BHT and CU Clean the housings, battery cartridge terminals, and CU-7001 charge terminals with a dry, soft cloth. Before cleaning, be sure to turn the BHT power off and unplug the AC adapter of the CU. • Never use benzene, alcohol, or other or- ganic solvents. The housing may be marred or the paint may come off. • Never [...]
