CHAPTER 3
INSTALLATION
3.1 INTRODUCTION
This chapter contains the information required to install the
PTRLNV/S3 and carry out preliminary checks.
3.2 UNPACKING
Remove the unit from its packing and, before anything else, ensure
that the unit has not suffered any damage during transit and that all
front and rear panel controls are operational.
3.3 INSTALLATION
1) This transmitter is able to operate from 4 different supply
voltages: 100, 120, 220 or 240 Vac, at 50-60 Hz.
First of all select the correct supply voltage using the selector
situated on the rear panel; use a screwdriver to raise the cover
(2 Fig.2) on which are written the various voltages, rotate it until
the arrow points to the correct voltage and re-insert it.
Check that a fuse is fitted to the cover and that its value
corresponds to the following:
220-240 Vac 2 A
100-120 Vac 3.1 A
2) Now ensure that the PWR ADJ control (10 Fig.1) is rotated fully
counter-clockwise for minimum power using a small srewdriver.
Since the control is a ten-turn potentiometer, it may be necessary
to double-check the adjustment.
Units are normally supplied with this control set to maximum.
3) Connect a dummy load with a continuous power rating of at least 10W
at the unit's required operating frequency, to the R.F. output
connector situated on the rear panel. A bypass Wattmeter should be
connected in series with this load in order to verify the reading
of the unit’s own internal wattmeter (SETUP 1 / Fig.4).
