tions are tip: left signal; ring: right signal; sleeve: common
ground.
When a plug is inserted in the front panel TAPE 2
IN jack, the circuits to the rear panel TAPE 2 INPUTS are
disconnected. Inserting a plug in the front panel TAPE 2
OUT jack does not disconnect the rear panel TAPE 2
OUT. It is possible to record from the front panel TAPE 2
OUT jack and the rear panel TAPE 2 OUT jack at the
same time. However, it is not possible to listen (or
monitor) from both the front and rear TAPE 2 IN jacks at
the same time.
THE ELECTRONIC MEMORY BATTERY POWER SUPPLY
A very long life, rechargeable battery power supply pro-
vides the energy for the electronic memory when the
receiver is turned off. When first connected, it is wise to
assume that the batteries have not been charged. The
charge rate is dictated by the 'on' time of the receiver. To
bring the batteries to full charge, leave the receiver turn-
ed on for twenty-four continuous hours. Programmed in-
structions will be retained for more than six months with
the receiver turned off if the batteries are fully charged.
After the batteries are fully charged, use for approximate-
ly one hour per week, will maintain the batteries in a fully
charged state.
HOW TO CONNECT AC POWER
A polarized AC plug is used on the MAC 4200. Plug it
into a 120 volt 60 Hz wall outlet. The plug blades must
be fully inserted in the outlet to prevent shock from ex-
posed blades.
CAUTION: TO PREVENT ELECTRIC SHOCK DO NOT USE
THE (POLARIZED) PLUG ON THIS UNIT WITH AN EXTEN-
SION CORD, RECEPTACLE OR OTHER OUTLET UNLESS
THE BLADES CAN BE FULLY INSERTED TO PREVENT BLADE
EXPOSURE.
Three types of AC power outlets are provided on the
back panel of the MAC 4200: 2 black, 2 green and one
red.
The black outlets are switched on or off when the
MAC 4200 is turned on or off. These are intended for CD
players, equalizers or other accessories, whose total
power requirement is 600 watts.
The red outlet is on at all times. For example, a VCR
(video cassette recorder) can be plugged into this outlet
for recording a TV program when the receiver is not turn-
ed on. Neither the red outlet nor the black outlets are
fused.
AC power to the green outlets are controlled by the
AUTOMATIC SYSTEM AC ON/OFF.
AUTOMATIC SYSTEM AC TURN ON/OFF
The POWER ON pushbutton shares AC power control,
with the AC power switch on a turntable, through a cur-
rent detecting switch circuit. On the rear panel, the TURN-
TABLE AUTO/MANUAL switch selects the mode of operation.
When the switch is in the AUTO position and a turn-
table plugged into one of the green AC power outlets,
the AC power to the receiver and to the black AC power
outlets can be controlled by the turntable on/off switch.
When AC power to the turntable is turned on, power to
the receiver and the black AC power outlets is turned on.
When in the automatic mode, the system will remain on
until the turntable is turned off. The POWER ON pushbut-
ton controls the AC power when using any source other
than the turntable.
In the MANUAL position only the red POWER ON
pushbutton will turn AC power on or off. Power from the
green AC power outlets can not exceed 100 watts.
Some turntables have electronic circuits that draw cur-
rent all the time. To use these turntables the
AUTO/MANUAL switch must be in the MANUAL position.
CONNECTING AN FM ANTENNA
Provisions have been made for the use of one of three
antenna systems: (1) an outdoor FM antenna, or (2) a VHF-
TV antenna, or (3) the indoor dipole supplied.
An outdoor antenna is recommended for optimum per-
formance in all areas. In fringe (outlaying) areas, best
results will be obtained with a highly directional FM
antenna used in conjunction with a rotator. If the antenna
uses a 300 ohm lead, connect it to the ANTENNA 300 ohm
FM push connectors.
If the antenna uses a 75 ohm coaxial cable, connect it to
the rear panel ANTENNA 75ohm type F connector.
An outside antenna system should not be located in the
vicinity of overhead power lines or other electric light or
power circuits, or where it can fall into such power lines
or circuits. When installing an outside antenna system, ex-
treme care should be taken to keep from touching such
power lines or circuits as contact with them might be
fatal.
A VHF-TV antenna can be effective when it is designed
for both FM and TV reception. Connect the two leads
from the VHF-TV antenna to the ANTENNA 300 FM push
connectors.
CONNECTING AN INDOOR
DIPOLE ANTENNA
The flexible folded dipole antenna (300 ohm) is for use
in urban or high strength signal areas. Connect the two
leads from the dipole to the ANTENNA 300 FM push con-
nectors.
The flexibility of the twin flat wire assembly permits it to
be placed under a rug, tacked behind the stereo...or plac-
ed in any other convenient location. In some cases, it
