not correspond to the product (e.g. a transmitter
update fi le instead of a receiver update fi le), the
"Product code error" popup window will appear
and the update process will not start.
Activate the control labeled "Program". Wait for
the progress bar to start. Depending on the speed
of the computer being used, this may take several
seconds. Now switch on the receiver while holding
its SET button down. After a few seconds the
"Found target device ..." message will appear
in the status display. Now you can release the
receiver's button. The actual fi rmware update
will begin autonomously after this message has
appeared.
However, if the receiver is not detected, the "Target
device ID not found" popup window will appear.
If this process terminates before reaching the
100 % mark, switch off your receiver's power supply
then try to start the update process all over again.
Do this by performing the above steps again.
The status display and progress bar will show you
the progress of the fi rmware update. The update
is concluded when the text "Complete ... 100 %"
or "Complete!!" appears in the bottom line of the
status display.
Both LEDs on the receiver will illuminate during
the update process. Upon successful conclusion
of the update process, the green LED will
extinguish and the red LED will begin to blink.
Switch the receiver off and remove the interface
cable. Repeat this procedure for any other
receivers present.
4. Receiver initialization
Following a successful update process you MUST
perform a receiver initialization procedure before
using the receiver again. This is necessary for
reasons of safety.
Do this by pressing and holding the receiver's SET
button then switching the receiver's power supply
on. Now release the SET button again. When you
subsequently switch the receiver on again, the
receiver's green LED will illuminate continuously
for about 2 or 3 seconds. Except for binding
information, all other settings that may have been
programmed into the receiver will now be reset
to factory defaults and will have to be re-entered
again if they are needed.
