  • Page 3: Safety Precautions

    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 prop- erty damage. Make sure you fully understand all definitions of these terms and related symbols given below, before you proceed on to the text itself.
  • Page 4 Handling the BHT • The BHT-7500W uses a laser light for scanning bar codes. The intensity of the laser light might be too low to inflict bodily in- jury. However, do not look into the laser beam.
  • Page 5 • Do not look into the laser beam through the reading window or point the laser beam 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 exposure.
  • Page 6 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, imme- diately turn off the power, pull out the rechargeable battery car- tridge, and contact your nearest dealer.

  • Page 10: Reading Bar Codes

    Reading Bar Codes Turn on the BHT power, bring the bar-code reading window to the bar code to be scanned, and press the trigger switch. The BHT emits a laser light to scan the bar code. When the BHT has read the bar code successfully, the indicator LED will illu- minate in green.
  • Page 11 • Before reading bar codes, clean those labels if stained. • Avoid using the BHT in direct sunlight. The BHT might fail to read correctly. • To read bar codes on curved surfaces, apply the BHT to the target bar code so that the code comes to the center of the scanning range indicated by the laser beam.
  • Page 12 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.

  • Page 13: Using Infrared Link

    Using Infrared Link CU-7000 Make sure that the BHT is securely in the CU-7000. Shield the IrDA interface from direct sunlight, intense overhead 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.
