Loading the Battery Cartridge
Before the first use of the BHT, be sure to load the battery cartridge as shown below.
The battery cartridge is not loaded in the BHT when shipped from the factory.
Loading the battery cartridge
(1) Turn the BHT upside down.
(2) As shown below, slide the battery cover lock in the direction of the arrow and
remove the battery cartridge cover.
(3) Check the polarity (positive and negative) of the battery cartridge. Then, load it
so that the end of the battery pull strap appears above the battery cartridge as
shown below. This facilitates easy removal of the battery cartridge.
(4) Put the battery cartridge cover back into place taking care not to pinch the
battery pull strap between its cover and the bottom cover. Then, return the
battery cover lock to its original position.
(5) Place the BHT on the CU-300 to charge the battery cartridge.

The BHT has an integrated rechargeable backup power source which backs
up the memory and calendar clock in the BHT when no battery cartridge is
loaded or the voltage level drops below the specified level. The backup
power source is automatically charged by the battery cartridge.
• When you first load battery cartridge after purchase or you load it afte
r
leaving the BHT unused for a long time, do not remove the
b
atter
y
cartridge for at least 10 minutes after that loading. This is for charging the
memory backup source integrated in the BHT.
• If you leave the BHT without the charged
b
attery cartridge loaded for
a
long time, the memory contents will no longer be backed up so that the
message "Contact your administrator.
N
ote the error number. (XXXX)"
or "Set the current date and time." may appear on the LCD.
• If you will not be using the BHT for a long time, follow the instructions
given in the "Battery Replacement Notes" on the next page.
