Operating
The main advantage of xDSL is the omission of the installation cost of new cable. The approved
maximum line length and the maximum sustained data transfer rate depends on the characteristics of
the cable.Before installing a xDSL modem the properties and quality of the selected pair of wires should
is corresponding to the demands of the chosen system.
Here helps the new KE2500, specifically designed for applications in telecommunications systems.

Battery calibration
The KE2500 is equipped with a high-performance lithium polymer (LiPo) battery. In spite of its low
weight, this allows an operating time of several hours in the measuring mode, under full load. The
capacity of the mains charger is sufficient to operate the KE2500 and charge the battery at the same
time, but the power supply should not be connected during ongoing measurements. This can lead to
a falsification of the measuring results in the case of critical lines. Thanks to a special charger, the
battery is carefully charged with time, voltage and current to ensure the longest possible service life.
Caution: The device may be operated only with the supplied original KE power supply, UMEC
UP0181A-09PE! Damage to the appliance resulting from non-observance will be repaired for
a fee!
Basically the PSU is only put on the unit and then into the wall outlet.
Note: Please fully charge battery before first use!
Changes the charging LED from orange to green the charging is completed. To check the charge
indicator after the initial charging turn off the device and then turn it on again with the AC adapter
connected for about 2-3 minutes. During this time, the battery indicator will be calibrated and now
displays the correct value.
