<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.
