SAFETY PRECAUTIONS Be sure to observe all these safety precautions. Strict observance of these warnings and cautions is a MUST for preventing accidents that could result in bodily injury and substantial property damage. Make sure you fully understand all definitions of these terms and symbols given below before you proceed to the text itself. Alerts you to those conditions that could cause serious bodily injury or death if the instructions are not followed correctly.
To System Designers: • When introducing BHTs in those systems that could affect human lives (e.g., medicines management system), develop applications carefully through redundancy and safety design which avoids the feasibility of affecting human lives even if a data error occurs. 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.
Handling the BHT • The BHT 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 complies with IEC 60825-1:1993+A2:2001 and 21 CFR 1040.10, 1040.11 except for deviations pursuant to laser notice No. 50, dated July 26, 2001.
• 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. • If foreign material or water gets into 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.
Components and Functions Liquid crystal display (LCD) Shows the characters and graphic patterns. Indication LED Illuminates in green when the BHT has successfully read a 2D code or bar code. Trigger switch (M4 key) Press this switch to start code reading. Trigger switch (M3 key) Press this switch to start code reading. IrDA interface port Used to exchange data/programs with the host computer via its integrated IR port or via the optical communication unit CU-300.
Trigger switch (M3 key) Trigger switch (M4 key) Cursor keys (F5 to F8) Used to move up to the preceding line, down to the next line, to the preceding character, and to the next character. Numerical keys Used for data input. Function keys Used for choosing functions. Power key Turns the BHT on or off. BS (Backspace) key Moves back one character. Magic keys (M1 to M4) Each of the M3 and M4 keys is assigned a trigger switch by default.
Reading 2D Codes and Bar Codes Turn the BHT on, bring the reading window to a 2D code or bar code to be scanned, and press the trigger switch. The BHT turns the marker beam (laser) and illumination LED on to indicate the scanning range and scan the target code, respectively. When the BHT has read the code successfully, the indicator LED illuminates in green and the marker beam goes off.
• The actual scanning range is narrower than the marker beam range. The scanning range is 2.4" (6 cm) wide by 1.6" (4 cm) high when the scanning distance is approx. 4.3" (11 cm). • The code reading procedure may differ depending upon the application used, so follow the application's manual. • Before reading labels, clean them if stained. • Avoid using the BHT in direct sunlight. The BHT might fail to read correctly.
Using Radio Link and Bluetooth® Wireless Communication Link The BHT-300QWB supports Bluetooth® wireless data communication. • If there are too many communications errors, first make sure that the BHT shall ® be directed at the target Bluetooth wireless communication equipment such 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.
Using Infrared Link Communicating with the CU Put the BHT directly on the CU as shown below. Interface connector (The CU is available in three models for the RS-232C, Ethernet (10Base-T), and USB interfaces.) Communicating with other IrDA-compliant equipment You can also have the BHT communicate with other IrDA-compliant equipment just by aligning their IR ports with each other.
Setting the Backlight Pressing the M4 key (right-hand trigger switch) while holding down the SF (Shift) key activates or deactivates the backlight function. Backlight OFF (The backlight function is OFF when you turn the BHT power on.) Press M4 while holding down SF. M4 (right hand trigger switch) Backlight ON Press M4 while holding down SF. If no key is pressed for 3 seconds. Press any key (except for the simultaneous depression of M4 and SF.) SF Backlight OFF (The backlight function is kept ON.
Adjusting the LCD Contrast & Beeper Volume and Switching the Beeper & Vibrator While holding down the M1 or M4 key (right-hand trigger switch), press the PW key, and the following screen will appear on the LCD. This screen will disappear if no keys are pressed for five seconds. When the beeper is selected (default) When the vibrator is selected When both the beeper and vibrator are selected (The current selection is highlighted.
Adjusting the beeper volume You can adjust the beeper volume to four levels from OFF to MAX. 1) Use the F5 and F6 keys to select the BEEPER VOLUME line. 2) To turn down the volume, press the F7 key; to turn it up, press the F8 key. After making the above setting, press the ENT key or no keys for five seconds. The new settings will be fixed and the above screen will disappear.
Loading the Battery Cartridge Before the first use of the BHT, be sure to load the battery cartridge as shown below. The battery cartridge is not loaded in the BHT when shipped from the factory. Loading the battery cartridge (1) Turn the BHT upside down. (2) As shown below, slide the battery cover lock in the direction of the arrow and remove the battery cartridge cover. (3) Check the polarity (positive and negative) of the battery cartridge.
Battery Replacement Notes When is battery replacement needed? If the "Charge the battery!" appears on the LCD, replace the battery cartridge with a fully charged one. If you leave the BHT without replacing the battery cartridge, the integrated calendar clock or data will no longer be backed up so that the calendar clock will stop or the "Contact your administrator. Note the error number. (XXXX)" will appear on the LCD. Be sure to turn the BHT off before battery replacement.
(2) When turning the BHT on after storage with no battery cartridge loaded: Even after removal of the battery cartridge, the calendar clock will work with the backup power source for a while. If the calendar clock backup has stopped, loading the battery cartridge and turning the BHT on will display the following message, prompting you to set the current date and time. For details about the setting procedure, contact your system administrator.
Error Messages If some error occurs when the power is turned on or during program execution, one of the following error messages will appear on the LCD.
