m) When Power is applied to this wire the backlight dims. We suggest connecting this wire to
your navigation light circuit.
3) Red (Always on Power) Connect this wire directly to your battery to power all functions except the backlight.
4) Green (Backlight Power) When power is applied to this wire the flight timer runs and the backlight is illuminated.
Connect this wire to your instrument power source so it is powered when your master switch is turned on.

Notes: Both the red and green wires should be on a fuse or breaker protected circuit. The value of the fuse/breaker can be as little as 0.5 Amp.

Operation:
Modes: The GT-50 has five modes.
PRESS the (Left) Mode button the switch between modes.
PRESS and HOLD the (Left) Mode button to display the Firmware Version number.

Accelerometer

PRESS the (Right) Action button to display the MAX and MIN G
readings.
PRESS the (Center) Reset button to clear the MAX and MIN G readings.

Occasionally the GT-50 must be recalibrated if it is not reading one G
when in level flight.

Level the instrument then PRESS and HOLD the (Center) Reset button
to calibrate the accelerometer to one G unit. The button must be held
until four dashes ---- appear on the display then released to complete
the calibration.

Clock

PRESS the (Center) Reset button to set the clock.
PRESS and HOLD the (Center) Reset button until the colon : begins
flashing to switch between 12 and 24 hour clock modes.

PRESS the (Right) Action button to adjust the hours or minutes when
they are flashing.

Timer

PRESS the (Right) Action button to start and stop the timer.

PRESS the (Center) Reset button to reset the timer to zero.

Flight Timer

The flight timer automatically runs when there is aircraft power applied to
connector pin 4 to keep track of your flight time and ground time for your
logbook etc. This mode is designated by a |- symbol in the left most
digit location.

PRESS the (Center) Reset button to reset the flight timer to zero.

Voltmeter

The instrument panel tilt angle is set from the Voltmeter mode. This step is only required if you have a panel angle of 30 degrees (SONEX aircraft).
Panel tilt of less than fifteen degrees has a negligible effect on the G reading. If power is removed from the GT-50 the panel tilt will revert to the
vertical panel setting of zero degrees when the power is restored. Note: Selectable panel tilt capability is only available on GT-50s with Firmware
Version 2.2 or greater.

PRESS and HOLD the (Center) Reset button to switch between zero and thirty degrees panel angle. Once the Panel tilt angle is displayed, release
the button to save the value that was displayed. The angle can be either zero degrees or thirty degrees.
