Connect the two wires of the 300 ohm
lead-in from the external antenna to the
MR66 back panel FM ANT terminals.
75 OHM ANTENNA
FROM VHF TV
ANTENNA
An unbalanced 75 ohm FM antenna may
also be used with the MR66. Connect the
center lead of the coaxial lead-in cable to the
right hand FM ANT terminal. Connect the
shield of the coaxial cable to the ground
screw next to the right of this same FM ANT
terminal.
VHF-TV ANTENNA
A conventional VHF TV antenna of the
type also suitable for FM may be used with
the MR66. Connect the two leads from the
300 ohm TV antenna lead-in wire to the two
FM ANT terminals on the MR66 back panel.
Connect a length of 300 ohm flat lead-in wire
from the TO TV SET terminals on the MR66
back panel to the antenna terminals of the
TV set.
The MR66 MODE SELECTOR switch auto-
matically switches the VHF TV antenna to the
MR66 in any of the " o n " positions. The
antenna is switched back to the TV set in the
POWER OFF position.
OPERATING INSTRUCTIONS
MONOPHONIC AM RECEPTION
Turn the MR66 MODE SELECTOR switch
to MON AM. Turn the FM FUNCTION switch
to FM OUT. Turn the AM FUNCTION switch
to any of the four bandwidth settings. It is
usually easiest to tune at the NARROW or
MEDIUM 1 position. After a warm up time of
approximately 30 seconds, turn the AM
tuning dial to the desired station. Depending
on the quality of the AM signal, select the
best possible bandwidth setting. (See the
section titled "AM FUNCTION SWITCH.":
The AM Signal Strength meter will indicate
the relative strength of the particular AM
station being received.
MONOPHONIC FM RECEPTION
Turn the MODE SELECTOR switch to
MON FM. Turn the AM FUNCTION switch to
AM OUT. Turn the FM FUNCTION switch to
MUTE IN. Set the AUTO FREQ CONTROL to
any position between MIN and MAX. (See the
section titled "AUTO FREQ CONTROL.")
After a warmup time of approximately 30
seconds, turn the FM tuning dial to the de-
sired station. The correct FM tuning point is
reached when the FM TUNING meter pointer
comes to rest anywhere in the center black
area of the meter scale. While tuning across
the dial you may notice movement of the
tuning meter, yet don't hear a station. This is
