CHAPTER II
INSTALLATION
2-1. UNPACKING.
Carefully remove the receiver from the shipping
carton and examine it for evidence of damage. If
any damage is discovered, immediately notify the
transportation company that delivered the receiver.
Be sure to keep the shipping carton and packing
material, as the transportation company will want
to examine them if there is a damage claim. Keep-
ing the carton and packing is recommended in any
case, as having these available makes packing the
receiver much easier should it ever be necessary to
store it or return it to the factory for service.
Inspect the packing material before putting it away
to be sure you have not overlooked any accessory
hardware. The hardware consists of two studs,
No.
l0-24,5/8
inch long, and two small rubber feet.
Examine your R-4C to make sure that all tubes
and crystals are properly seated in their sockets.
NOTE
Fill out the enclosed registration card
and return it to the factory immediately
to insure registration and validation of
the warranty.
2-2. LOCATION.
The location of the R-4C is not critical, as long as
allowance is made for adequate air circulation.
Avoid extremely hot locations. It is recommended
that a minimum clearance of one inch be main-
tained at each side of the R-4C. Do not cover the
top with books, paper, or pieces of equipment.
With the studs and rubber feet supplied, it is
pos-
sible to position the R-4C for either of two alter-
nate viewing angles, as shown in figure
2-l.
To
con-
vert the R-4C to either option, the first step is to
remove the bottom cover from the receiver. Re-
move the bottom row of three screws on each side
of the receiver, and the cover can be removed.
Remove the rear feet, and snap the small rubber
feet into the holes just outboard from the original
rear feet. For option B, put the bottom cover back
on the receiver. For option C, remove the front
feet from the receiver, invert them, and remount
them on the same screws. Then thread one of the
accessory studs into each of the remounted front
feet. Finally, mount the feet that were removed
from the rear of the receiver on the studs, and put
the bottom cover back onto the receiver.
2-3. POWER REQUIREMENTS.
CAUTION
Operation of this receiver with the wrong
power source may result in serious dam-
age.
Refer to figure 2-2. As shipped from the factory
the R-4C is wired for 120 Volt
50/60
Hz AC
operation. The receiver may also be operated from
240 V AC by removing the retaining tab and plac-
ing the 120/240 Volt slide switch on the rear panel
in the 240 Volt position. Replace the retaining tab
on the opposite mounting screw to prevent the
switch from accidentally being returned to the
120 V position. Operation of the receiver from
240 V with the switch in the 120 V position will
cause serious damage.
2-4. GROUND.
A screw terminal is provided on the rear panel for
connection to the station ground. Also, if used with
the T-4XC transmitter and other accessories, con-
nect a ground strap between the ground terminals
of all units.
2-5. ANTENNA.
The jack labeled ANT is the connection point for
the antenna. The nominal impedance of the circuit
is 52 Ohms.
