ANTENNA CONNECTIONS

●

Each antenna should be connected to the designated terminals correctly, referring to the following figure.

●

Both AM and FM indoor antennas are included with this unit. In general, these antennas will probably provide sufficient signal
strength. Nevertheless, a properly installed outdoor antenna will give clearer reception than an indoor one. If you experience
poor reception quality, an outdoor antenna may result in improvement.
