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.
• Be sure to turn the BHT off before battery replacement.
• Replace the battery cartridge quickly. 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.
