4 Operation
Replacing the accumulators
The battery compartment for the three accumulators
(rechargeable batteries) is located on the back of the case.
Unscrew the screws to remove the cover of the case and
insert the accumulators in accordance with the polarity
marking.
Use only NiMH accumulators.
The current state of the charge will (if the ARGUS is not
connected to a power supply) be displayed graphically.
In the LCD display, a battery symbol will begin to blink, when
there is still approximately 5 minutes reserve. During this
period, it is possible that there may be audible interference
and in rare cases even malfunctions (Seite 133).
Power Down
In accu/battery operation, if the ARGUS is idle for 15
minutes, it will automatically switch to the power-down mode
(power-down). The ARGUS will remain in power-down
mode until the Power-Key is pressed again.
Reasonably enough, the ARGUS will not enter power-down
mode during a test (e.g. Loopbox) or when it is in Trace
mode.
As an alternative, it is possible to operate the ARGUS using
the included power supply. When the power supply is
connected,
the
disconnected.
The ARGUS can also be powered from the BRI line. In this
case, it does not need accumulators or the plug-in power
supply.
Whenever the ARGUS is powered from the plug-in power
supply or the BRI line, the power-down mode is reasonably
enough not active.
