The indication will appear for about 5 seconds, unless
the two pushbuttons are not pressed again.
The diagnostic also gives an indication of low battery (B
on the right lower corner of the display) corresponding
to a voltage of 11.2 V. If the battery voltage is below
10.2 V, but higher than 9.5 V, the display will show as
in fig. 3-38 for 1 minute, then the HeliTest
automatically is switched off.

When this message is displayed, disconnect the
battery unit and recharge it or change it.
3.4 OPERATION WITH AC/DC CONVERTER
When HeliTest is powered by the AC/DC converter P/N
969-3535, the “battery check” voltage reading should
be between 12 and 13.8 V, and the AC/DC converter
LED should be red (fig. 3-37).
The AC/DC converter LED will change to green when
HeliTest is switched off.
3.5 SHUT-DOWN
To shut down HeliTest from any operating mode, or
during start-up self test, press the OFF pushbutton.
NOTE
During configuration change operations the HeliTest
cannot be switched-off.
