Upgrading Firmware
The EzOSD is equipped with a built-in USB port, with a standard connector, commonly found on most
portable USB equipment (technical name is a mini-B).
Upgrading firmware requires no additional hardware, programmers, or returns to the factory. All that is
required is a standard USB cable, and a utility which may be freely downloaded from the ImmersionRC
website.

Diagnostics, Q/A
Q. The OSD is taking along time to acquire satellites, or is not very precise when flying
A. This is a common problem in our hobby. The GPS receiver is extremely sensitive, and is generally
placed in close proximity to a powerful video transmitter. To solve this, keep the GPS as far from the
video transmitter as possible.
2. Speed/Altitude not accurate when flying 3D
The GPS antenna is directional, and is similar to the patch antennas that we use commonly for video.
When throwing a plane around the sky, diving rapidly, flying inverted, etc. this directional antenna may
well not be facing towards the satellites which provide its position. During these times, it is normal for
the GPS readout, especially speed, and altitude, to be in-precise. When level flight is returned, the
readings will correct themselves.
