2.4 Replacement of the Backup Battery

If the following warning message appears on the LCD, you need to replace the backup battery (refer to

Section 2.4.1).

If you remove the backup battery, 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 PC.

This warning message appears each time the backup battery is fully discharged after 200 times of full

discharges.

Even if this warning message appears, you can continue operation by tapping the OK button in the top

right corner of the message window.

Each time the backup battery is fully discharged, the internal discharge counter automaticall

increments by one; however, replacing the backup battery does not reset the counter to zero

automatically. You need to reset the discharge counter (refer to Section 2.4.2).

When the BHT is shipped from the factory, the discharge counter is reset to zero.
