INSTALLATION
3.1 INTRODUCTION
This chapter contains the information required for installation of the
TEX20-N.V. exciter and for preliminary checks.
3.2 UNPACKING
Remove the unit from its packaging and before any other operation, check
for any damage that the unit may have suffered in transit and that all front
and rear panel controls are functioning.
3.3 INSTALLATION
1) Check on the rear panel that the line voltage selector is correctly
set for the local supply. If not, remove the cover (2 Fig.2A-2B) on
which the voltages are printed and rotate it until the required
value corresponds to the arrow, and reinsert it.
Check also that the fuse mounted inside the cover is present and
in order.
The current capacity of the fuse are as follows:
220-240V - 2A
100-120V - 3.15A
2) Now ensure that the PWR ADJ control (7 Fig.1A and 4 Fig.1B) is rotated
fully anti-clockwise, using a small screwdriver.
Units are usually shipped with this control already at minimum.
WARNING: When the unit is switched on with the control at its minimum
position, power output is about 2W.
3) Connect R.F. output connector (6 Fig.2A-2B) to antenna cable.
4) Inject Audio signal coming from external source, to MONO or MPX
connector (it depends from the type of the external source).
5) Connect line power to the unit via the VDE socket (1 Fig.2A-2B),
switch on the equipment through power selector (9 Fig.1A and
8 Fig.1B).
6) Select PWR/FWD power measuring, through the selector
(10-11 Fig.1A and 3-5 Fig.1B) placed on the front panel, and adjust
PWR ADJ trimmer to obtain the reading of 20W on the analog meter (1
Fig.1A-1B).
7) Now, Select DEV measuring through the selector PWR/DEV (10 Fig.1A
and 3-5 Fig.1B) and adjust INPUT LEVEL trimmer (of the relative Audio
