• Do not remove operating batteries and the
memory backup battery at the same time (this
will result in the loss of all stored data).
• Backup important data before replacing batteries.
• Remove an installed PC card before replacing
batteries. If the PC card has its own batteries,
check that they are not depleted before removing
the card from the unit.
• Replace both operating batteries at the same
time with new batteries of the same type.
• The memory backup battery is installed at the
factory. It drains slightly during shipment and
distribution, so it may not achieve the lifetime
indicated in the specifications.
Caution:
• Keep batteries out of the reach of children.
• If the unit will not be used for a long period of
time, turn the unit on once a month and confirm
that BATT doesn't appear at the top of the display
(or replace the batteries beforehand). Leaving
spent batteries in the unit may cause battery
leakage and damage from corrosion.
• Do not dispose of batteries in a fire, this may
cause explosions.

Important points to remember when installing new
batteries:
• Be certain to use alkaline batteries with your unit
under normal conditions. We also recommend
that you use High Energy Lithium batteries L91
(size AA) or an external power supply (such as
the EA-23E AC adaptor or the CE-BK1 recharge-
able battery pack) while using high-power cards
such as Fax/Modem cards. Constant usage of
many high-power Fax/Modem cards will deplete
a fresh set of alkaline batteries in about 20
minutes, for example. Lithium batteries will
perform significantly better under these condi-
tions. Under normal operating conditions,
however, Lithium batteries do not perform
significantly better than alkaline batteries and
may not be cost effective. Be sure to best match
your battery selection to your particular usage.
• Be sure not to use manganese batteries or nickel
cadmium rechargeable batteries. These are
easily mistaken for alkaline or lithium batteries.
