6. To check voltage at connections, see Figure 9
on page 10. FOLLOW THE NUMERICAL SE-
QUENCE ON THE DRAWING AND CHECK
VOLTAGE AT:
#1. LNBF voltage. Disconnect the coax cable from
the LNBF. Check voltage from the middle wire to
the shield. There should be +12 to +19 VDC. If no
voltage is present, make sure receiver is on and
check again for +12 to +19 VDC at ends of gray
coax cable.
#2. ëMini-cableí connection voltage at Control Box.
#3. Coax cable at Control Box going to DVB box.
#4. Coax cable at DVB box going to Heyco connector.
7. Are the dip switches in the correct position
(101, 119 or 092)?
8. If the unit still does not have a signal, power off and
power back on.
IF YOU DO NOT HAVE A SIGNAL:
1. The signal may be blocked by trees, hills or struc-
tures. Pull into an area where no trees or buildings are
in the line of sight from unit to the satellites.
2. Check your +12 VDC power switch. Make sure
it is in the ON position.
3. Check your connections. The receiver must be
connected to the power and coax connected from re-
ceiver to the satellite dish. Check demultiplexer
connection.
4. Check your power supply. The +12 VDC power
supply must be hooked up. Check for +12 VDC on the
roof at the connector.
5. Is the rear adjustable base bracket facing the rear
of the vehicle? See Figure 1, page 4.
6. Loss of signal may also be caused by snow on roof
of vehicle.
NOTE: The power rocker switch must be ON for the
next steps. Voltage must be +12 VDC, except at the
LNBF, see #2, Figure 9, page 10.
Troubleshooting
Signal strength screen meter shows some
signal strength, but constantly moves up and
down, and is never locked on satellite.
Unit continues to move, but never finds any signal.
The unit continues to move and the signal strength
screen shows that it is finding the satellites, but will
never lock onto any satellite. Continues to search.
The unit moves around in circles, then points off the
front of the coach.
The unit moves in circles and does not find the sat-
ellite, then begins to make grinding noise.
Check your power voltage. You may have unfil-
tered power. You must have a minimum of 12 VDC
to power the LNBF. If the LNBF shows no signal
strength, the unit will move and operate, but you will
not be able to lock onto a signal.
PROBLEM SOLUTION
Be sure the switches are set on the correct numbers ó
see page 5, step 5.
The GPS is not acquiring a signal.
Power unit off, then on.
Check switches to make sure they are set correctly.
