FM MODE button
Auto Stereo: Normally, select this mode (by making
the HI-BLEND and MONO indicators disappear from
the display window) when you tune in a strong FM
broadcast.
HI-BLEND:
Select this position
when
the high-
frequency sound is noisy in the FM band. The high-
frequency noise will be reduced, but this lowers the
stereo effect.
MONO: Select this position when you tune in a very
weak or noisy FM station.
Although the sound will
come out in monaural the noise will be greatly re-
duced.

CHARACTER button
Press this button when you record an FM stereo pro-
gram using the Dolby NR* (Noise Reduction) system.
The MPX FILTER indicator appears.
This filter cuts off the 38 kHz subcarrier signals, which
may otherwise interfere with proper operation of the
Dolby NR* (Noise Reduction). If your deck has an MPX
FILTER button, use that button rather than the button of
this tuner.
* Dolby noise reduction manufactured

Corporation.
"DOLBY"
and the double-D symbol [{U] are trade-
marks of Dolby Laboratories Licensing Corporation.
