Troubleshooting

IF YOU DO NOT HAVE A SIGNAL:

1.The signal may be blocked by trees, hills or structures. 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 receiver 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 11.

6.To check voltage at connections, see Figure 9 on page 11. FOLLOW THE NUMERICAL SEQUENCE ON THE DRAWING AND CHECK VOLTAGE AT:

#1. Power Supply.

#2. 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 for +12 to +19 VDC at ends of gray coax cable (remove at box junction).

#3. ‘Mini-cable’ connection voltage at Control Box. #4. Coax cable at Control Box going to

Heyco connector.

7.Are the dip switches in the correct position (101 or 119)?

8.If the unit still does not have a signal, power off and power back on.
