Before Use

for several hours after a power shutdown, giving you the time

from the ProFlex 800
Unless the battery has already been taken out, do the
following:
• Open the battery trapdoor, accessible from above the
ProFlex 800, by lifting and then turning the quarter-turn
finger screw anticlockwise. This releases the two springs
located under the battery, pushing the battery slightly
upward (see picture).
• Grab the battery and take it out of the compartment.
