LED Low Battery

The red "Low Battery" LED warns the user that the batteries have reached
a critical state. When this LED lights up, you should be sure to recharge
the tester before you use it again. If you continue using the VIT-A2 DSL
Tester even though the "Low Battery" LED is lit up, the tester will
automatically power off after a certain time in order to avoid a total
discharge of the batteries.
Stationery operation with an AC adapter is an alternative, of course. The
tester will automatically switch from battery power to AC power without
interrupting the current measurement as soon as an external power source
is connected to the DC jack.
4.3

LED Charge

The orange "Charge" LED lights up as long as fast charging of the
batteries is underway in the tester. As a prerequisite, the flip switch on the
front side of the housing must be in the "Off / Line Test" position and then
an external power source (car battery or AC adapter) must be connected
to the DC jack.
As soon as charging is complete (this will take about three hours when the
batteries are fully discharged), the "Charge" LED will go off and the tester
will switch over internally to trickle charging.

LED Line Test

The green "Line Test" LED indicates whether a remote power supply for
an analog or ISDN connection is present on the line as long as the flip
switch is in the "Off / Line Test" position. This LED can indicate the
following:
LED Line Test not lit up:
No power has been detected on the line. This can mean the following:
•
A relevant service (analog or ISDN) is not provided on the line
•
The measurement was made accidentally behind the splitter on the
user side
•
An error exists in the connection of the a/b wires.
