Maintenance
CAUTION
Pay special attention to the following information for the
Lithium battery pack:
• Do not short-circuit the contacts.
• Keep the battery away from fire.
• Do not expose the battery to temperatures above 60°C (such
temperatures may occur, for example, in a car left in the sun, or
in direct sunlight).
• Take care that the battery does not become wet.
• Take care that the battery is not exposed to impacts, blows, etc.
Do not drop it. Do not step on it by accident.
• Do not take the battery apart or modify it in any way.
• The performance of the battery decreases with the
temperature.
7.2.1.2 Optimal operation of the battery
The battery is charged automatically when the plug-in power supply
on the back of the instrument is connected and is plugged into a
mains socket (100–240 Volt/50–60 Hz).
CAUTION
Use only the manufacturer's specified external power supply
to operate the instrument and charge the internal lithium
battery pack. The specified power supply and it's plug shape,
it voltage rating (12V, 2A) and it's electromagnetic
characteristics are critical to assuring the DR 2800's
performance and the safety of the user.
Important Note: We advise charging the battery at an ambient
temperature between 10°C and 30°C, as this is the range in which it
can be most effectively charged to 100%.
7.2.1.3 Lifespan of the battery
The battery has a limited lifespan. The more it is used, the more its
capacity is reduced. If a fully charged battery only allows the
instrument to be used for a relatively short time, replace the battery
with a new one.
Note: You need not run down the battery completely before recharging it. If
you recharge the battery when it still has some residual charge, this does
not reduce its capacity!
