NOTE
Muting removes the annoying noise between FM
stations. The muting circuitry may prevent the
receiver from distinguishing a very weak signal
from interstation noise. To tune in very weak
stations, defeat the mute circuit by releasing
the FM MUTE switch to the out position.

Figure 2 - Connecting AM Antenna
Connecting To External TV Antenna
For optimum performance, a separate FM antenna is recommended. If a TV antenna must be used for both FM and
TV reception, install an FM signal splitter at the end of the
transmission line, as shown in figure 4.
GND
The Model TP160 has an internal FM Line Antenna which
may be used for receiving FM broadcasts. For improved
reception, particularly in weak signal areas or for tuners
mounted in consoles or racks, installation of an outdoor FM
or “T” antenna is necessary. If you are installing a standard
300-ohm antenna system, connect the twin-lead transmission
line as shown in figure 3a. If conditions require use of a
coaxial transmission line, such as
connect the cable as shown in figure 3b. Coaxial cable must
be used when the transmission line is run in conduit.

To decrease the audio output from the tuner, turn the
LEVEL control counterclockwise. To increase the audio
output, turn the LEVEL control clockwise.
