SELFTEST IS ON; ON-BATTERY SELFTEST screen (Figure 11) – shows that
an On-Battery Selftest is active with the unit internally switched to power from
the internal battery pack, which should already be connected within the unit. The On
Battery LED is also lit during this test. The unit will also test to see if an optional
external battery pack (Model SBATT) is connected to the unit. If no external battery
pack is connected to the unit, the message displayed in Figure 12 ( NO EXTERNAL
BATTERY CONNECTED ) will be displayed.
