Controls & Indicators
Display – Indicates the operating frequency in kHz. The trailing decimal point indicates that either AC or DC power is applied to the receiver. Memory mode operation is indicated by the leading decimal point in the display.
Tuning (VFO) – The tuning wheel and the ~~ and buttons are the primary tuning controls of the receiver. Clockwise rotation of the dial increases frequency in kHz steps and counterclockwise rotation decreases frequency in kHz steps. The ~~ and buttons increment and decrement the frequency in kHz steps.
Program Buttons (0)-[9) – Numeric buttons permit direct entry of receive frequency in kHz from 100 to 30000 kHz.
VOLUME – Turn this clockwise to increase the volume setting. Turn this control counterclockwise to reduce the volume setting.
RF GAIN – This control adjusts the RF gain of the receiver and is normally set for the fully clockwise position. Turn the control counterclockwise, as required, to reduce the receiver gain for reception of strong signals.
SPEAKER – This is the opening for the internal speaker of the receiver.
HEADPHONE JACK – This connector accepts a 1/8″ stereo/mono headphone connector. Reception is monaural only.
Installation / Setup
The setup of the SW1 AM Shortwave Receiver involves several key steps. After unpacking the unit and the included AC Adaptor wall transformer, inspect them for any damage. For operation from a 12 VDC vehicle supply, ensure proper polarity connection between the vehicle’s lighter or accessory socket and the coaxial DC power plug. The outside metal shell of the power plug is the negative connection, while the inside metal contact is the positive connection. For fixed installations, connect the antenna system to the appropriate antenna input and system ground to the screw terminal marked ‘GND’. Plug the output cable of the AC Adaptor into the ‘POWER INPUT’ connector on the rear panel of the receiver, and then plug the AC Adaptor into a 120 VAC, 60 Hz power source. Location is not critical, but for fixed locations, the receiver should be operated from the AC Adaptor. Keep flammable materials away from direct contact with the AC Adaptor to avoid overheating.
Operation
The SW1 AM Shortwave Receiver is designed for easy operation with features that allow for convenient tuning and connection. The receiver can be tuned using a tuning wheel, tuning buttons, or by direct numeric entry. It operates from either an AC adaptor or a 12 VDC power source. The front panel controls provide rapid tuning to a specific frequency, and the RF Gain is adjustable via a front panel control. The receiver includes dual antenna input terminals for versatile connections and a front panel LED display for frequency readout.

Safety & Warnings
To reduce the risk of fire or electric shock, do not expose the product’s AC adaptor to rain or moisture. Do not open the cabinet; refer servicing to qualified personnel only. To prevent electric shock, do not use the AC adaptor with an extension cord or other outlets unless the blades can be fully inserted without blade exposure. Keep curtains and other flammable materials away from direct contact with the AC adaptor to avoid overheating the transformer, which could result in failure.
