49Downloading a firmware packet
Version “V4”. If you neglect this, individual compo-
nents could malfunction. The same applies to future
software packets, i. e. “V5” or higher.
In contrast, if changes are made to individual firm-
ware files within a particular version “VX”, then it is
sufficient to install just the later firmware version for
the corresponding product. The easy way to check
whether firmware updates are available is to look at
the creation date of the download file. The version
numbers of the associated firmware files also change.
Now save the compressed file in a folder of your
choice, and unpack it using a suitable program.
If a transmitter update fails to work as described in
the following section, please read the chapter entitled
“Restoring your transmitter firmware” on page 52.
