When is battery replacement needed?
If the "Charge the battery!" appears on the LCD, replace the rechargeable battery
cartridge with a fully charged one.
If you leave the BHT without replacing the rechargeable battery cartridge, the
integrated calendar clock and data stored in the BHT can no longer be backed up.
The calendar clock may stop and 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.
• 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 the BHT 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.
