Section 3 - Modes and Alarms

Modes

There are two standard operating modes of the FS-450:

Automatic

Indexing

, and

Manual Indexing

. Most of the time you will

operate the FS-450 in the Automatic indexing mode. When you
first turn on the power the FS-450 starts in the Manual indexing
mode, but will enter the Automatic indexing mode after a minute.
Tapping the

AUTO

button will begin the Automatic Indexing

Mode. The indicator lights show you what is being displayed in the
lower digital display.

Alarms

The FS-450 has programmable alarms. When the remaining
amount of fuel falls below the alarm limit the lower display will
show the amount of fuel REMaining and the REM indicator light
will flash.

When the remaining time falls below the alarm limit the lower
display will show the MINutes of fuel remaining and the H.M.
indicator light will flash.

When an alarm is displayed, tapping the

STEP

button will

temporarily disable the alarm indication for the next ten minutes.

When an alarm is displayed, holding the

STEP

button until the

word

appears will disable that alarm indication for the

remainder of the flight.
