5.7.4. ANALOG ROAMING GAIN
This is a critical parameter, which
may not be realigned to different
values other than factory default. It
controls the gain for an IP received
audio frame to be modulated into
local channel in analog mode.
Under your risk, if you still prefer to
realign the Analog Roaming gain,
you must select
Roam. Analog Gain
on Alignment screen.

Actual alignment value will be
displayed on alignment slider.
Press [Start] then move the slider to
reach the desired value.
As soon the desired value is
reached, press [Finish] to store the
value on repeater memory.
If you want to retrieve factory
default, press [Factory] instead of
[Start]. You will be asked to confirm
the factory default alignment, and
then if you confirm it, original
values from factory will be loaded
into current alignment settings.
5.7.5. VOCODER OUT GAIN
This is a critical parameter, which

values other than factory default. It
controls the gain applied to the RX
vocoder to control internal level of
received digital audio. It also adjust
the volume of the AdPCM frames
transmitted from the IP port for
roaming considerations.
Under your risk, if you still prefer to
realign the Analog Roaming gain,
you must select
Vocoder Out Gain
on Alignment screen.
