An antenna trimmer allows the rf circuit to be accurately peaked at any part of any
band.
The
rf gain
control
allows
the
sensitivity
of
the
receiver
to be
adjusted
to"
accommodate both weak and strong received signals.
The receiver operates on 115V 60 Hz ac power only and draws only 18 watts of power.
Any
low impedance (50 to 75 ohm) antenna or transmission line may be connected to
the convenient antenna terminals at the rear of the receiver.
Careful attention should be paid to the "Installation" and "Operation" sections of this
manual. These sections give information for the satisfactory operation of your Model 500
receiver.
The Model 500 has a very high degree of sensitivity needed to receive weak and distant
signals. Careless operation or poor installation of this high-sensitivity receiver may cause
an excessive amount
of noise or background
hiss. Careful adjustment of the tuning,
volume, and gain controls, as outlined in the previously mentioned sections, will keep
these undesirable effects to a minimum.
Installation
As mentioned
earlier, proper
installation goes
hand-in-hand
with correct operating
procedures to get maximum performance from your receiver. Read this section carefully
to become familiar with the correct installation of your receiver.
Location. The cabinet of the Model
500 is equipped with four small feet which are
suitable for placing the receiver either on a shelf, desk, or table. When you locate the
receiver, try to avoid excessively warm
places, such as near radiators or heaters. Warm
locations may cause the receiver to drift off frequency. Be sure to allow at least one inch
clearance
between
the rear of the cabinet and the wall to give the receiver proper
ventilation.
Electrical Power. The
Model
500 is transformer-operated and will operate only on
115 volt, 60 Hz ac power. It uses 18 watts of power. If you are in doubt about your
power source, call your local power company before you plug the power cord into the
power
outlet. Connecting
the receiver to the wrong power
source can cause serious
damage and costly repairs to the receiver.
