- 18 -8. Battery InformationThe battery information function provides the following information.• Battery voltage (mV)• CU installation status (charge status)• Battery level• Battery typeThere are six battery levels.The battery level is “HIGH” when fully charged and continues to drop to “MID” and then “LOW” and so on as theBHT is used.If a key is pressed or the touch panel is tapped when the battery level is “LOW”, the beeper will sound three timesand a ”Battery voltage low” message displays. This message will not display again until the BHT is nextsuspended or resumed.If use of the BHT is continued even when the battery voltage is low, the beeper will sound five times, a “Pleaserecharge battery.” message displays, and the BHT automatically goes into suspend mode. It will then not bepossible to resume the BHT until the battery has been sufficiently charged.Level VoltageHIGH 3.9 V or aboveMID Less than 3.9 VLOW Less than 3.7 V (Beeper sounds once and message displays.)WARNING Less than 3.6 V (Beeper sounds three times, message displays, and BHTsuspended automatically.)CRITICAL Less than 3.4 V (BHT does not operate.)NO_BATTERY No battery installed (BHT does not operate.)The actual battery voltage may differ depending on how the BHT is used. Barcode reading and wirelesscommunication and so forth exert a large load on the battery and therefore the voltage level may display lowerthan the actual level at such times. A message displays and the BHT switches to suspend mode at such timesalso.Ensure to always use a lithium-ion battery.
