Mast-Mount Amplifier (150-1108) Troubleshooting Faxback Doc. # 7232 If you have poor FM radio reception, be sure the FM TRAP switch is set to OUT. If the reception is poor on all units connected to the amplifier: - Be sure the house unit is plugged into a live AC outlet. - Check all connections between the antenna, the antenna unit, and the house unit. If you have poor, or no, reception on only one unit of a multiple receiver system that is connected to the house unit: - Check all F-connectors for damage. In particular, examine the center pins. - Be sure the F-connectors are properly attached. - Verify that the TV or FM receiver operates properly when used with other signal sources. If the FM trap has no effect on the TV picture, the source can be from other types of interference. You might need additional filters or traps. (br/all-7/19/94)
