If victim is not responsive
follow the A-B—C's of basic life support
- Place victim flat on his backon a hard surface.
- Open airway: lift up neck, push forehead back
~ clear out mouth if necessary and observe for breathing
- if not breathing, begin artificial breathing (Figure 2): tilt head, pinch nostrils,
make airtight seal, four quick full breaths. Remember mouth to mouth
resuscitation must be commenced as soon as possible

GENERAL DESCRIPTION
NT 1000 Transmitter Exciter
INTRODUCTION
The NT 1000 LCD Exciter is the latest in state of the art products available
from Nicom. This Transmitter is designed with high reliability components and is
intended to give many years of trouble free continuous service. This unit
incorporates many features including a switching power supply and a PLL
frequency synthesizer.
The latest SMD technology has allowed to makea more compact unit (only 3
rack spaces) and at the same time a very light unit (only 45 lbs).
The same technology has developed a new Mosfet (SD2942) capable of more
than 350W output;
the use of three of them delivers a 1100 W output that is more than enough to
allow a continuous 1000W output.
INSTALLATION
After unpacking the unit, check for any mechanical damage or loose parts
inside .lf there is any transportation damage, inform immediately the supplier
and do not put the module into operation.
The applicable voltage is 220-240V only.
Ensure that the station's ground system connections have a ground
resistance of less than 5 ohms. The equipment’s cabinet must be effectively
grounded
Check that the transmitters main switch is off.
Connect the power cord to the AC plug.

TECHNICAL FEATURES
FRONT PANEL COMMANDS AND SIGNALING
The front control panel carries the power on switch, the control meter, some
alarm warning LED‘s and a RF monitor connector. On the bottom, a panel grid
for ventilation.
1) This is the main AC power switch; the unit will shut down completely with
this switch.
Always keep it off before connecting the antenna
2) This multifunction LCD display allows the reading of the FonNard power,
reflected power and modulation level.
After few minutes it shut off and to resume it you must push one of the
two square programming buttons.
3) This is the trim pot to adjust the forward power of the transmitter. Rotate
gently clockwise to increase the power. If you exceed the nominal power the
protection will shut down the power itself
4) These two push buttons are used to program the frequency of the
transmitter and to set a password. (see programming)
5) At the RF monitor output, (BNC type), a sample of the output power is
available which is typically attenuated 50 dB .This is useful for a direct reading
with a Spectrum analyzer to verify the spectrum purity, harmonic emissions etc.
6) This Red Alarm Indicator inhibits the unit when something is wrong. There
could be 3 different
causes for the LED to lit; a) when too much driving power is given from the
exciter (overdrive)
b) when the temperature of the heat sink goes over 60 degrees Celsius
c) when more than 10% reflected power is detected by the
VSWR circuit sensor.
In any of these circumstances the unit goes off the air and for reset
it the only way is to turn off the main AC switch and turn on
again after few seconds. If the problem has been removed the
Red LED should stay off othenNise you should refer to one of our
technicians.
7) This LED indicates that all the power supplies are working properly.
8) This LED indicates that the unit is locked at the desired frequency.
9) This LED indicates that the transmitter is ON-AIR.

STARTING PROCEDURE
Connect the antenna cable to the ‘7/16 DIN’ connector on the back of the
unit. The antenna system must be set up to operate at the transmitter's
working frequency. ‘
ATTENTION
Antenna matching is extremely crucial for PM transmitters. Operate this unit
only after verifying good matching. Mismatching will decrease the
communication distance and unduly stress the semiconductors.
Turn on the transmitter. You should see the "WAIT" message appear on the
LCD Display.
After few seconds the green LED “PLL LOCK" should turn on. This
indicates that the frequency is locked on the programmed value. In the display
will appear a sequence of squares.
After few more seconds the “RF ENABLE” green LED will come on. This
indicates that RF power is being delivered to the output connector on the back.
You can now increase the output power through the small trim pot located in the
front panel and identified with " RF ADJ.”
Increase slowly till you reach the power you need; keep always an eye at the
Reflected power reading to verify that the antenna is well operating. The
indication of the reflected power is on the right side of the display "RFL".
Once you have reached the desired power level, you should wait till the unit
warms up (30 minutes)
Now you can input modulation. For MONO operation connect your signal to the
XLR connector or BNC, Depending on the model. Following the connecting
instructions printed on the back of the transmitter and then regulate the input
level with the apposite trimmer. For stereo input, use the BNC connector
labeled "MPX".
Regulate the audio with the apposite trimmer.
Note: Be sure that the modulation level is close to but not more than 75KHz.
75KHz is 100% modulation. Lower modulation level will decrease the SIN value
while over~modulation (>100%) will cause distortion at the receiver and it is
against current regulations.
