3. How to Use：

Before Powering-Up the System

All connection must be made before powering up the system. Ensure the GPS antenna is facing up and not

blocked from the sky. Make sure all components are securely fixed in the plane. The GPS must be kept away

from all electronic components, especially the electrical speed controller, video transmitter and wireless mo-

dem transceiver.

Before Taking-Off

Connect battery for the on-board video system if there is any, turn on the ground video receiver and display

system. Turn the RC transmitter on, make sure the throttle stick is pulled at the low position. and then connect

the power battery to power up the OSD system. If there is any separated battery pack for RC receiver, power

the RC receiver up before the power battery is connected. Place the plane at the taking off position, and keep

it to be stationary until the position is locked by the GPS, and the HDOP reading is not more than 3. It may

take some time for the position to be locked, and the HDOP reading is dropped to 3 in the poor weather con-

dition. It is not recommended to take off if the HDOP reading is more than 3.

After Taking-Off

You may take off the plane after a standard range check for the radio system and the plane condition before

the flight. Do please prepare to return to the take off position and land the plane when:

- The power battery is low

- The video battery is low

- The video link is not stable

- The RSSI reading is low

- The HDOP reading is close to 3

- The GPS signal quality indication is low

And the plane must be landed as soon as possible when:

- The video link is not stable

- The RSSI warning is indicated

- Any GPS failure is indicated

- The HDOP reading is suddenly increased for more than 3

After Land ing

After landing, you may press the red reset button on the infrared remote controller while the OSD system is in

the in-flight interface screen to reset the Relative Altitude, Maximum Altitude Reached, Distance to Home,

Home Direction and also the Timer (if it is set to the “Take-Off Start” mode) back to zero. In the same time,

the home position recorded in the system will be replaced by the current location coordinate.
