Install thereafter the console in the LogiBit amplifi er. Make sure
that the connections on the console and the amplifi er fi t into
each other. Finally screw in the 3 screws in the top panel of
the
amplifi
er.
Installation of aerials
Assemble the two aerials (YW570 75 Ohm), and install the BNC
on the WTU console:
aerial sockets on the console. The aerials should be at an angle
of 90 degrees from each other to give maximum coverage. The
2 aerials cover both receiver 1(REC1) and receiver 2 (REC2).
Installation of
When installing external aerials (YW570 75 Ohm) with cable
external aerials:
length of up to 30 meters, the cable should be RG-59 type and
have an impedance of 75 Ohm. Cables longer than 30 meters
should be type RG-11. The aerial should be mounted high and
free on the wall. The aerial, cable or receiver should not be
placed near high frequency noise generating equipment, for
example, fl uorescent lights or computers. Aerials should be at
least 8 meters from each other if installed in the same room
to give the best possible coverage. There should be a minimum
of 3 meters between an external aerial and a receiver.
Squelch:
The squelch on receiver 1(REC1) and 2 (REC2) can be adjusted
with a small screwdriver on the trim control. Turn the trim
control fully to the left and the receiver is least sensitive, i.e. it
requires high levels of noise to activate the receiver. Turn the
trim control fully to the right and the receiver is most sensitive,
i.e. it only requires low levels of noise to activate the receiver.
Installing 3 extra
Remove the blank panel as described in point 2 (Removing the
microphone/line inputs:
blank panel) in section 3.2. Install the console in the LogiBit
amplifi er as described in point 3 (Installation of WTU module)
in section 3.2. Make sure that the connections from the console
and the amplifi er fi t in each other. Finally screw in the 3 screws
in the top panel of the amplifi er.
3.3 INSTALLATION OF FRONT TO 19” RACK:
Remove all 4 screws from the front of the amplifi er. The existing
front can then be removed. The new front can now be installed
using
the
4
original
screws.
3.4 FUSES AND 115/230 VOLT AC EXCHANGER:
The fuse compartment can be opened by placing a screwdriver
under the fuse compartment and pressing the screwdriver down
carefully. Use a 4 AT fuse for 115 volts and a 2 AT for 230 volts.
If the equipment is connected to 115 volts turn the voltage
exchanger in the fuse compartment to show 115. Likewise at
230 volts turn the exchanger to show 230. Then reinsert the
fuse
compartment.
