• 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.

battery

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.
