1. Figure 2 17 Loss of Airspeed If the Gemini loses airspeed or is not connected to a Pitot system the airspeed tape will become a ground speed tape This will only occur if the ground speed is greater than Vso Bottom of the white arc The background color of the tape will change to yellow to indicate that it is not displaying airspeed but is in backup mode displaying ground speed note Even if not connecting to the Pitot Static system both ports MUST be open to the cockpit 18 AS tape displaying ground speed Setting DG If GPS Signal Is Lost If the GPS signal is lost the DG will enter the free gyro mode This mode has no track or heading reference so the DG must be set against a compass heading or other directional reference There are several options for changing the DG direction 1 To stop the DG from drifting left press and hold the control key and to the right of the DG box The longer these keys are held the more the drift will be reduced 2 To stop the DG from drifting right follow the same procedure as in 1 but touch to the left of the DG box Once the drift has been removed DG stopped the following procedure can be used to set the DG value 1 Hold the key on the side of the DG box that corresponds to the desired DG direction The longer it is held the faster the DG will move Release the key when the desired value is displayed in the box 19 4 e Bei 060 070 080 090 2 4 Mov2. be for all products except the Pictorial Turn amp Bank which will continue to have a warranty of one year from the date of purchase 22 This page intentionally blank Za Return Merchandise Policy And Procedure Under no circumstances should products be returned to TruTrak without first obtaining a Return of Merchandise Authorization number RMA from TruTrak An RMA may be obtained by contacting us at 866 878 8725 Products that do not have an RMA will not be processed Please include documentation stating the reason for the return and describing any symptoms failure modes suspected causes of damage diagnostics performed data collected etc Product s should be packaged in their original shipping containers In lieu of this they should be very carefully packaged in containers suitable to protect them during transit For your protection items should be insured for the full value Note that damage caused during shipping will not be repaired under warranty The outside of the box must be clearly marked with the RMA issued by TruTrak and the RMA must also be noted on the return documents Products will be returned to the customer at no charge via FedEx Ground or UPS Ground If customer requests expedited shipping 24 Day or Overnight they will be charged the shipping cost and must supply a credit card number INTERNATIONAL SHIPMENTS TruTrak sends all International shipments with an insurance value on all products The

PS backup for 18 eee loss Instrument Installation Mounting Considerations The Gemini PFD unit is designed to mount in the aircraft instrument panel Maximum recommended viewing angle should be no more than 20 deg The maximum mounting angle the instrument can accommodate is 10 degrees longitudinal axis and 0 degrees lateral axis The primary unit location should minimize pilot head movement when transitioning between looking outside of the cockpit and viewing operating the instrument The location should be such that the instrument is not blocked by the glare shield on top or by the throttles control yoke etc on the bottom Use aircraft installation standards for mounting and support of the instrument Wiring Considerations Use AWG 24 or larger wire for all connections unless otherwise specified The standard solder pin contacts supplied in the connector kit are compatible with up to AWG 18 wire In cases where some installations have more than one component sharing a common circuit breaker sizing and wire gauge is based on length of wiring and current draw on units In these cases a larger gauge wire such as AWG 20 may be needed for power connections Do not attach any wires to the outside of the instrument or route high current wires within six 6 inches of the programmer Ensure that routing of the wiring is not exposed to sources of heat RF or EM interference Check that there is ample space for the cabling and
