(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 administra-
tor.
(The indication "00/01/01 00:00" will vary depending upon the calendar
clock state.)
• The rechargeable battery cartridge can be recharged hundreds of times,
but it will eventually wear out. If the run time is noticeably shorter than
normal, replace the battery cartridge with a new one.
• Use only DENSO-authorized battery cartridges and chargers.
• Never dispose of batteries into a fire.
• When disposing of battery cartridges, cover their terminal pins with vinyl
tape to prevent short-circuit.
• Batteries should be recycled properly. Do not throw them in the trash.
