Immediately following installation, the first time the device is turned on, it is absolutely fundamental that the
instructions outlined in this chapter be followed. Failure to perform the adjustments and controls explained in this
section could cause serious damage to the device or interference with other broadcasters or services that operate via
radio; any such damage will be the sole responsibility of the user.
8.1.a
Initial start-up and basic adjustments
The first time the device is turned on, it is important to perform basic adjustments (frequency, output power, modulation, etc.) and
verify that they are functioning correctly (e.g., reflected power) via the commands menu. This section explains how to perform these
adjustments.
,
The transmitter stores in its memory the operating mode in which it was working before the power supply was turned
off or a mains failure took place. Therefore, before continuing, it is important to ensure that it is connected to a load
that is able to support the maximum deliverable power.
,
Operating the transmitter without an antenna, or when the antenna is improperly connected, may cause damage that
is not covered by the warranty, particularly during the final stage of transmission.
,
If turning the transmitter on places it directly in operation (rather than on stand-by), we recommend that the
ON/STAND-BY button be pressed to place the transmitter on stand-by while making adjustments.
,
Proper adjustment of the parameters should be made so as to conform to local regulations; such conformity is the full
responsibility of the user.
For questions regarding navigation of the commands menu, refer to Chap. 9.
If the device is left on the
SETUP
menu without receiving a command, the display will automatically return to the
STATUS
screen
under the
VIEW
menu (

section 10.2.a).
1)
Ensure that all installation conditions are met, as described in Chap. 6, and that all the connections described in sections 0,
6.4.b, and e 6.4.c have been made. You can connect a suitable dummy load to the transmitter’s RF output instead of the
antenna.
2)
Turn on the device via the rear power switch (
2
section 5.2 ref. [5]). For a few seconds, the Siel logo will appear on the full
screen; after this, the default screen will be displayed (
2
section 10.1); the bottom of the default screen will show the two
main menus,
VIEW
and
SETUP
:
3)
At this point, two conditions are possible:
The transmitter begins to operate
(including possible powering up) – the display turns on, and the
ON
LED lights up in green. In
such case, it is recommended that the basic settings be made, turning the transmitter on stand-by. To do so, press the ON/STAND-BY
button. Ensure the
ON
LED lights up in yellow and skip directly to step 4).
The transmitter goes to stand-by
– the display turns on, and the
ON
LED lights up in yellow. At this point, proceed to the next step.
4)
Turn the knob to select the main
SETUP
menu, and press briefly to confirm. The first of the three pages comprising the
SETUP
menu (
