3. INSTALLATION
To install the PM1000:
1. Connect an antenna or a dummy load to the RF output connector.
2. Verify the correct main supply voltage (230 VAC or 115 VAC).
3. Control that the main ON/OFF switch on the rear panel is in the OFF position (labelled “0”).
4. Connect the transmitter to the main power supply using the power cord included.
5. Switching ON the transmitter: on the front panel (Fig. 1.1) you will see the “MAINS” led ON.
6. Control that the “LOCK” led (Fig. 1.1) on the front panel lights up a few seconds after the power
is turned on.
7. Select the FWD setting, using the Measure select button (Fig. 1.1).
Adjust, looking at the front panel meter, the output power by means of the “PWR” potentiometer
on the front panel (Fig. 1.1).
WARNING: The transmitter can work properly within ± 10 % of the nominal main supply voltage
and is designed to support main supply spikes, although it is preferable to use the main voltage
stabilisers to reduce the risk of damage.
