<Note 1>: The operation time data shown above is for refer-
ence only. The actual operation time depends on the opera-
tional condition or circumstance.
<Note 2>: The more time the nickel hydride battery is
charged or discharged, the maximum capacity decreases.
<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-discharges, it is rec-
ommended 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, shorter 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 batteries.
