About Status Indicators Battery voltage level Shows the current battery voltage level. If the voltage level is high, three bars appear; if low, a single bar appears. The displayed battery level shows the terminal voltage of the battery cartridge, not how much power is left. Connection state in radio communication The battery voltage level varies depending upon the operation of the BHT, so the displayed level also may vary .
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 illuminate in green. Bar code scanning range covered by the laser light Indicator LED Trigger switch (M4 key)* Max. 56 cm (22.0")** Trigger switch (M3 key)* PW key * The trigger switch function is assigned to both of the M3 and M4 keys by default.
• 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. • When you pull the bar-code reading window away from bar codes, the actual scanning range will become narrower than the range covered by the laser beam.
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 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.
