Guidelines To prolong the life span of the battery, follow the guidelines
below:
– WARNING: Danger of extreme heat, fire, or explosion if
battery is tampered with. Use only JDSU approved Li-ION
battery. Dispose of used batteries according to the manu-
facturer's instructions.
– Do not keep the AC adapter connected continuously.
Disconnect the charger about once a week and operate
the T-BERD ⁄ MTS 5800 using battery power for a period
of time (two or three hours is recommended). If you have
another T-BERD ⁄ MTS 5800 and battery, rotate the
T-BERD ⁄ MTS 5800 and battery so that the battery gets
off of the charger and gets used for some period of time
about once a week, or as often as possible.
– When not connected to the unit, store the battery in a
cool, dry, and clean environment. Do not leave the battery
in a car or truck, particularly during extremely hot or cold
weather.
– Do not place a property label on the T-BERD ⁄ MTS 5800
under the battery. The label can interfere with the align-
ment and seating of the battery. Place labels on the side
of the unit.
– Use the AC adapter to power up the T-BERD ⁄ MTS 5800
the first time you use it or after prolonged storage.
– If the battery capacity is depleted or if the battery has
been stored for a prolonged period, use the JDSU battery
charger to charge the battery. Do not use an un-approved
charger.
– The charger will not charge the battery when it is
extremely hot or cold.
– Always carry a fully charged spare battery.
See “Checking the battery” on page 28 for information on
checking the battery status.
