Each time you add fuel to the aircraft the Fuel Remaining (as shown on the FP-5 in the REM Display
Mode) needs to be updated. This procedure was described previously in the Display Modes and Operating
Features section of this manual.
4. USED Programming Mode (Setting the Low Fuel Reminder and Low Fuel Warning Alarms):
In the USED Programming Mode the following functions may be set:
Low Fuel Reminder Alarm -
A low fuel alarm may be programmed to blink the Low Fuel Warning LED
when the fuel remaining reaches your programmed set point. Pushing any button or switch will turn off the
blinking LED. This limit is intended as a reminder. It may be set to remind you to switch tanks or when a
specified amount of fuel remaining in the tanks has been reached. A good point to use in setting this alarm is
at the 1/3 fuel remaining level. In the REM Display Mode a bar in the upper left corner of the display will
be shown when the Low Fuel Reminder limit has been violated. Programming this alarm to 000 disables the
alarm.
Low Fuel Warning Alarm -

this alarm is thirty minutes worth of fuel (at cruise) for a VFR pilot or forty-five minutes for an IFR pilot. In
the REM Display Mode a bar in the lower left corner of the display will be shown when Low Fuel Warning
limit has been violated. Programming this alarm to 000 disables the alarm.
