SAFETY PRECAUTIONS Be sure to observe all these safety precautions. Strict observance of these warning and caution indications are a MUST for preventing accidents which could result in bodily injury and substantial property damage. Make sure you fully understand all definitions of these terms and related symbols given below, before you proceed on to the text itself. WARNING Alerts you to those conditions which could cause serious bodily injury or death if the instructions are not followed correctly.
WARNING • Do not carry or store the battery cartridge together with metallic ballpoint pens, necklaces, coins, hairpins, etc. Doing so could short-circuit the terminal pins, causing the batteries to rupture or the battery fluid to leak, resulting in a fire or bodily injury. Do not shortcircuit me! • Avoid dropping the battery cartridge or letting it undergo any shock or impact. Doing so could cause the batteries to break, generate heat, rupture or burn.
CAUTION Handling the rechargeable battery cartridge • Never charge a wet or damp rechargeable battery cartridge. Doing so could cause the batteries to break, generate heat, rupture or burn. Handling the BHT • 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. I'm burning up! Doing so could affect the housing or parts, resulting in a fire.
CAUTION • Never disassemble or modify the BHT; doing so could result in an accident such as break or fire. Never disassemble • 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. Keep me away from water! • If foreign material or water gets into the BHT, immediately turn off the power, pull out the battery cartridge, and contact your nearest dealer.
Components and Functions Indicator LED Illuminates in green when the BHT has successfully read a 2D code or bar code. Touch screen LCD (liquid crystal display) Shows the characters and graphic patterns. You may directly touch the screen with the stylus for data entry. Trigger switch (M4 key) Press this switch to start code reading. Trigger switch (M3 key) Press this switch to start code reading.

Reading 2D Codes and Bar Codes Turn the BHT power on, bring the reading window to the target code, and press the trigger switch. The BHT turns three marker LEDs on to indicate the scanning range and the illumination LED to scan the code. Keep the BHT stationary in a position where the target code lies between the right and left markers and the center marker comes to the center of the target code. Hold the reading window 4 to 14 cm (1.6 to 5.5 inches) away from codes to be scanned.
• Before reading 2D codes or bar codes, clean those labels if stained. • Avoid using the BHT in direct sunlight. The BHT might fail to read correctly. • To read 2D codes or bar codes on curved surfaces, apply the BHT to the target code so that the code comes to the center of the scanning range indicated by the markers. • Depending upon the code size or cell pitch, the proper scanning distance from 2D codes or bar codes will differ. At the scanning time, the marker LEDs and illumination LED will come on.
Using Radio Link • If there are too many communications errors, first make sure that the BHT points directly at an access point because the 2.4-GHz band requires a more or less straight line path. Note also that the low-power radio waves have trouble passing through human bodies and other obstacles along that path. • This link will not operate properly in the vicinity of microwave ovens, industrial heaters, high-frequency medical equipment, and other sources of radio waves in the 2.4-GHz band.
Using Infrared Link ■ CU-7000 Make sure that the BHT is securely in the CU-7000. Shield the optical interface from direct sunlight, ambient intense lighting (inverter-driven fluorescent lighting, in particular), and other potential sources of infrared radiation. Sources to watch out for include remote control units for television sets and the like.
