Replacing the accumulators
The compartment for the four 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 the accumulators included
in the package. 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
(depending on the mode of operation) 15 minutes reserve. During this period, it is possible
that there may be audible interference and in rare cases even malfunctions (see page 136
Accu Servicing).
Power Down
In accu operation, if the ARGUS is idle for 15 minutes (adjustable see page 132), 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 accumulators are automatically disconnected.
Unplug the power supply from the mains, as soon as the ARGUS is no longer in
use and switched off.
Regardless of the type of supply used, you should always operate the ARGUS with
accumulators installed. This will ensure the uninterrupted operation of the real-time clock.
