5. Quick guide for installation and use
This section provides a step-by-step description of equipment installation and
conguration procedure. Follow these procedures closely upon rst power-on
and each time any change is made to general conguration, such as when a new
transmission station is added or the equipment is replaced.
Once the desired conguration has been set up, no more settings are required
for normal operation; at each power-up (even after an accidental shutdown),
the equipment defaults to the parameters set during the initial conguration
procedure.
The topics covered in this section are discussed at greater length in the next
sections, with detailed descriptions of all hardware and rmware features and
capabilities. Please see the relevant sections for additional details.
IMPORTANT: When conguring and testing the transmitter in which the equipment
is integrated, be sure to have the Final Test Table supplied with the equipment ready
at hand throughout the whole procedure; the Final Test Table lists all operating
parameters as set and tested at the factory.
5.1 Preparation
5.1.1 Preliminary checks
Unpack the amplier and immediately inspect it for transport damage. Ensure that
all connectors are in perfect condition.
The main fuse can be accessed from the outside on the rear panel. Extract the fuse
carrier with a screwdriver to check its integrity or for replacement, if necessary.
The following fuses are used:

Dopo aver effettuato i collegamenti descritti al paragrafo precedente, accendere
l’amplicatore agendo sull’interruttore di alimentazione presente sul frontale.
Accendere anche l’eccitatore di pilotaggio.
5.2.3 Power check
Ensure that the ON light turns on. Machine name should appear briey on the
display, quickly followed by forward and reected power readings (gure 5.2 - menu
1). If RF output is disabled, these readings will be zero.
5.2.4 How to enable Local mode and the RF output
Check current mode setting and enable Local mode (if not already enabled)
following menu path Fnc ⇒Loc ⇒Local (gure 5.2): if left disabled, the machine
will not accept the next commands.
Check current RF output setting and enable output (if not already enabled) following
menu path Fnc ⇒Pwr ⇒ON (gure 5.2 - menu 4).
Check output power level and set to maximum level (if not already set to maximum)
from the Power Setup Menu, which you can call up by pressing these keys in the
order: ESC (opens Default Menu) ⇒ENTER (hold down for 2 seconds) ⇒SET
⇒ use key to set bar to maximum limit (gure 5.2 - menu 2).
5.2.5 RF output power level control
IMPORTANT: The amplier incorporates Automatic Gain Control and output
power is modulated based on the power level set by the user and actual operating
conditions, such as temperature, reected power and other parameters. Drive
power must be kept steady at maximum output power capacity. Please read section
5.3 for more details of RF power modulation.
Open the Powersetupmenu (gure 5.2 - menu 2) pressing the following keys
in the order:
ESC (opens Default Menu) ⇒ENTER (hold down for 2 seconds).
Use SET menu and keys to set the desired amplier output power; the SET
bar at the side provides a graphic display of set power, whereas the forward power
value shown on the display (Fwd:xxxxW) gives actual output power reading,
andmaybelowerthansetpowerifanAutomaticGainControlisinlimited-
