2.3.3 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, then the integrated calendar clock or data
will no longer be backed up so that the calendar clock may stop or the data may be lost.
Grip style BHT
If "Charge the battery!" appears on the LCD when battery cartridges are loaded in both the BHT body
and grip, replace both battery cartridges. (As long as the voltage level of either one of battery cartridges
is higher than the specified level, this warning message will not appear.) Always remove both battery
cartridges, even if you only have one fully-charged replacement battery cartridge on hand.
• Replace the battery cartridge quickly.
• Be sure to turn the BHT off before battery replacement.
• Load a charged battery cartridge within 3 minutes after the removal to avoid data loss.
• After battery replacement, turn the BHT on and check its operation.
• If you leave the BHT with no battery cartridge loaded for a long time, the contents of the memory
may no longer be backed up so that the data stored in the BHT may be lost. It is recommended that
important data be saved into the FLASH folder or uploaded to the host computer.
• The battery cartridge will gradually deteriorate during the repeated cycles of charging and
discharging due to its properties. When the battery operation period becomes shortened due to its
deterioration even if it has been charged for the specified hours, replace the battery cartridge with a
new one.
• Use only DENSO WAVE-authorized battery cartridges and chargers.
• Never dispose of battery cartridges into a fire. They should be recycled properly. Do not throw them
in a trash.
• When disposing of the battery cartridge, cover the terminal pins with vinyl tape to prevent
short-circuit.
