FM Antenna Input

The FM antenna input socket is designed to accept a 75-ohm 'co-axial' cable. If you want to connect an antenna with a 300-ohm twin-lead wire, use the supplied 300-to-75 ohm 'balun' adapter.

AM Antenna Terminals

An external antenna will be needed for AM reception. For most local broadcasting stations a simple wire up to one meter (three feet) in length will provide ample signal strength.

Troubleshooting Guide

No Sound Issues

Power not turned on. Line cord unplugged, or plugged into dead outlet. Internal fuse blown; return product to dealer for service.

One Channel Audio Loss

Connecting cable pulled loose or making poor contact in socket. Rotate plugs in sockets to restore contact. Short-circuit in a defective connecting cable.

Distorted FM Reception

'Multipath' reception. Rotate antenna to find the orientation that provides best reception. Raise the height of the antenna.
