Generally, on cassette decks, adjust the recording level
so that the peak meters to —4dB, and on reel-to-reel
tape decks the peak level meters deflect as close as
possible to 0dB. However, depending on the broadcast
programs
or
the
tapes
you
use,
some
further
ad-
justments
may
be necessary.
You can
determine
the
most
appropriate
recording
level
for your
tape deck
after several trials, using the suggested levels as a star-
ting point.
To deactivate the cal tone circuit, press the CAL TONE
button again.

scanning,
press the button again.
During manual
tuning:
Press and keep the TUNING
button depressed to change the frequency continuously
until the figures in the frequency
display window
ap-
proach the desired frequency. The frequency figures will
change
rapidly. To change
the frequency
slowly
(in
0.05 MHz
steps) to tune in a station accurately,
press
the button and release immediately.
When the frequency figures reach the end of the tuning
range, the frequency will then be scanned from the op-
posite end of the tuning range.
