Use the up and down buttons to select a value between 63 and 100 %. The default setting is 63%,
which corresponds to approximately 31 V for the related fan voltage. A setting of 100% corresponds to
approximately 48 V for the related fan voltage. Press the accept (checkmark) button to save the change.
Press
X
to abort the change and return to the previous menu.
NOTE
: A 20% reduction in fan speed can yield up to 5 dB improvement in acoustic noise from the
transmitter, as well as decrease power consumption (i.e., utility costs) and extend the operating life of
the cooling fans.
UPS Installed
NOTE
: You can also adjust the UPS Installed setting using the AUI (see Hardware Configuration, on page
3.2.109 ).
From the controller UI, you can configure the transmitter for the installation of the UPS interface kit,
which allows operation with an external, user-provided UPS. If you have upgraded your transmitter
with the UPS interface, you may have already been prompted to change this configuration. To view the
UPS Installed
screen, select
System Settings -> HW Config -> UPS Installed
from the
Main Menu
(see Figure 3.2.108 ).
