The LxT cannot be operated with an
external power supply if the internal
batteries are discharged (flat). You
can run solely on external power if
you remove the depleted batteries.
However, if operated on external
power only, with no batteries
installed, an interruption of power to
the LxT, for any reason, may result in
instrument malfunction. The PSA029 is designed to work on power systems
worldwide.
The LxT must run on batteries until allowed by the host to
run on external power. If the batteries cannot provide
sufficient power, the LxT does not power on, even with
external power. If batteries are installed in the LxT, ensure
that they are good so that the LxT can power on.
Power Settings
If the LxT is ON, pressing the
0
(ON/OFF) key brings up
the Power Control Page, as shown in FIGURE 3-7.
