Cautions
• If the battery pack is discharged quickly even after its recharging, the battery service life has

expired.  Replace it with a new one.  (The built-in battery pack and CMOS backup cells are
service parts.)

• The standard recharging times listed above are typical values in an ambient temperature of

20°C to 25°C.

• It may take up to 1.5 times longer to recharge the battery pack if the PC is being used.
