5.5. MAIN REPEATER ALIGNMENT
Before setup any parameter, run
SDRe programming software then
select Repeater Alignment from top
bar menu.
A complementary message will be
displayed on the time the software
detects the repeater connected to
USB port on the computer.
If the repeater is not connected,
then the program will be timed out
after 20 seconds.
As soon as the repeater is detected,
actual repeater parameters are
loaded.
Once the repeater is connected, a
new screen pops up showing all
alignment parameters. The
software downloads actual
alignment parameters stored into
repeater
memory, so the
information displayed on each
alignment step is the real value
form the previous alignment.
The repeater also stores in a special
memory area, original values
assigned in factory. You can go
back to those values anytime for
any particular alignment step.
In case the repeater is password
protected, dealer password is
required to access to this alignment
menu.
At any time, press
to end
the alignment procedure then the
repeater will returns to alignment
menu.
For any transmit related alignment
parameter, low power will be used,
except on RF power alignment.
