Notes about the

A rechargeable lithium-ion battery is the
only kind that can be used. Even if the
battery supplied with the unit is not used,
you should charge it at least once every
three months to maintain the battery.
The rechargeable battery can be
charged approximately 300 times.
Do not use any battery other than that
specified. Use of other batteries may
cause malfunctions.
When the operating time is reduced to
about half the normal amount of time,
even after a full charge is performed, re­place the battery with a new one.
When charging or when using the re
chargeable battery, use it within an am­bient temperature range of 41

95”F(35”C).

If the rechargeable battery is used in a
cold environment, the operating time

be reduced.
