Backup Battery
This instrument has a last-memory feature. When you turn the power on, the instrument
starts with the panel settings that were in use the last time that it was turned off. If the
backup battery is out of power, the message “The last memory feature is disabled.” will be
displayed, and this feature will no longer work.
To continually use the last-memory feature, we recommend that you replace the backup
battery with a new one every five years after you purchase the instrument. You cannot
replace the backup battery yourself. Contact your local LEADER agent.
