(left photo on previous page). Push back the cover (middle
photo), remove the old battery (right photo) and insert a fresh
battery in the correct orientation. Then replace the cover,
pushing it forward until you feel and hear a click.
After you replace the battery, the LCD will “wake up” and
begin displaying real-time readings. If the MODE button is not
pressed within 60 seconds, the LCD will be automatically
powered off.
Note: If the battery is removed from a unit before it has been
set up from software or while it is recording, the unit must be
reconfigured before it can be reactivated. If it is not
reconfigured, the unit will remain in standby mode.
