IMPORTANT NOTES
1.
While installing the VR-70 Demodulator, the DCM Down-converters
and/or the UCM Up-converters, the power supply of the down-converters
and the up-converter should be disabled in the Setup configuration menu
(line no.6 and 13 respectively) of the rack-mount modulator, to avoid
short-circuit risk.
2.
Audio subcarriers of frequencies lower than 7,02MHz are not compatible
with 6MHz PAL-D system.
3.
The VR-70 repeater and demodulator is able to transmit 6MHz PAL-D
signal.
4.
There is an incompatibility in the Audio1 subcarrier frequency between
PAL-BG and PAL-D standards equipment.
5. High performance levels, in terms of audio, video and radio frequency,
that this equipment is capable of providing, can only be guaranteed if high
quality cables and connectors are used.
6.
To prevent unwanted manipulation of the VR-70 Demodulator rack-
equipment, a Torx TX20 screwdriver has to be used to remove the upper
cover. An example of such a screwdriver is the Wera brand 367 BO model.
7.
SVP Broadcast Microwave has approved Rosenberg and Suhner video
and RF connectors. If these brands are not used, select another high quality
brand.
8.
SVP Broadcast Microwave has approved Suhner and Draka intermediate
frequency, radio frequency, video and audio cables. If these brands are not
used, select another high quality brand.
9. Signal level in the down-converter is more precisely measured with the
MD-70 signal meter than with the demodulator.
10.Performance figures of this equipment should be measured after it has
been in continuous operation for 2 hours.
