OPERATING THE FT-1

The FT-1 should be plugged into an AC power source that is not usually turned off. Once plugged in, the unit may
be operated either from its front panel or from the remote controller.

)
Ensure that the tuner is in MONO mode ("STEREO" in display not illuminated). Pressing and holding down the UP
button will cause the displayed frequency to increase. Similarly, holding the DOWN button down will cause
the frequency to decrease.
When the top or bottom of the FM band is reached, the display will continue to tune up or down in the band from
the top or bottom. For example, if you continue to press the DOWN button after the display reaches "87.50" it will
begin again at "108.50". And, it will continue tuning in the downward direction until the DOWN button is released.
A similar reaction in an upward direction will occur if the UP button is pressed continuously.
To return to stereo reception, press the STEREO button.

Press the UP or DOWN button and release. The display will begin ranging up or down in the direction selected. It
will stop at the first station that is transmitting in stereo and is being received at a signal strength sufficient to
provide at least 50dB of quieting. It will stay tuned to that frequency until the UP or DOWN button is pressed
again. To stop the seek mode, press the STEREO button twice.
Note: The seek speed will be noticeably slower than when it is scanning in mono mode. This is due to the fact that
UNISET's digital circuitry is continuously sampling the output from the front end for (a) a station that is
transmitting in stereo mode, and (b) at a signal strength that will provide full quieting (50dB or better). And it
must do this in 50Khz steps.

FUNCTION
This function is useful in helping to control strong signals that abound in urban areas due to the large number of
FM stations that are usually concentrated there. When the "DX" symbol is showing in the display window,
the FT-1's front end is set for maximum sensitivity. When the DX button is pressed, the FT-1's sensitivity will be
reduced by some 18dB. The lessened sensitivity will decrease the amount of incoming signal thereby reducing
the possibility of interference and noise caused by strong, local signals.
Pressing the DX button switches the FT-1 alternately between DX and non-DX modes. The DX symbol illuminated
in the display window indicates that DX has been invoked.
Note: DX should be invoked at all times except when reception of a given station is actually improved by turning
it off. It is also essential the DX mode be invoked whenever the 'Seek" method of tuning is being used.
STEREO/MONO
Pressing the STEREO button will alternately switch the FT-1 between 'stereo' and 'mono' reception mode. When
the 'stereo' mode is invoked, the "STEREO" symbol will be illuminated in the display window.
Note: When "STEREO" is displayed it is actually indicating the presence of the 19KHz stereo pilot signal being
transmitted by the FM station. If the station is not transmitting in stereo, the STEREO indicator will not be
illuminated.
