panel end cap) until the meter pointer is
centered on the zero scale marking.(Tuner
Serial Nos. 1N001 to 1N961 have recessed
screwdriver-adjust AM meter control near
back of tuner chassis.)
In areas where noise or interference is
high, the meter may move above the zero
position when the AM antenna is recon-
nected to the back panel terminals. This is
normal and does not affect the meter op-
eration.
FM TUNING METER
Turn the FM FUNCTION switch to FM
OUT position. (The meter pilot lamp turns off
but the circuit is still on.) All other controls
and switches may be in any position. Allow
the tuner to operate for approximately
5 minutes. The FM tuning meter pointer
should rest in the center of the black scale.
To adjust, rotate the red FM MTR ADJ
thumb wheel control (under right dial panel
end cap) until the meter pointer rests in the
center of the black scale. (Tuner Serial
Nos. 1N001 to 1N961 have a screwdriver-
adjust FM meter control near back of tuner
chassis.)
AM AND FM OUTPUT LEVELS
Adjust each control until the MR66 AM
and FM output volume levels are equal to
each other. They should also be equal to the
volume levels of other signal sources (such
as phono) connected to the control pre-
amplifier. You can now switch the pre-
amplifier from the MR66 to other program
sources without need for readjusting the
main preamplifier volume control.
DIAL PANEL LIGHTS
Adjust the brightness of the dial panel
lights by means of the lamp slide switch on
the MR66 back panel. Set the switch to HI
position for maximum dial light. Set the
switch to LO for a dimmer light and extended
lamp life.
