<Note 1>: The operation time data shown above is
for reference only . The actual operation time depends
on the operational condition or circumstance .
<Note 2>: The more time the nickel hydride battery
is charged or discharged, the maximum capacity de-
creases .
<Note 3>: The data shown above is measured using
nickel hydride batteries that has been fully charged
just before . Because a nickel hydride battery self-dis-
charges, it is recommended to charge nickel hydride
batteries just before using . Also it is recommended to
use batteries whose self-discharge rate is low (e .g .,
SANYO eneloop) .
<Note 4>: Use eight batteries of the same type and
same capacity .
<Memo>: Lower the operation temperature is, short-
er the life of a primary battery (e .g alkaline) is .
When you use the unit in a place where temperature
is low, it is recommended to use nickel hydride bat-
teries .
