Initialization

When the power switch is turned on, the GY501 automatically
obtains the reference signal for AVCS function correction and
initializes itself.

During initialization, the message **INIT* appears on the GY501
LCD screen.

Do not move the helicopter until this message disappears (in
about 5 seconds).

Also, do not move the transmitter rudder stick from the neutral
position during this period.

Precautions When Turning on the Power Switch
