The SW1 offers good sensitivity, selectivity, dynamic range and features that permit easy tuning of desired stations. Conveniently located front panel controls allow for rapid tuning to a particular frequency. The SW1 is easy to use. The operating frequency can be tuned via a tuning wheel, / tuning buttons, or by direct numeric entry. The RF Gain is adjustable via a front panel control. Dual antenna input terminals on the rear panel provide versatile and practical connection of either a coaxial 50 Ohm feedline or wire antenna connection to the receiver. A front panel LED display shows the receive frequency. Memory mode operation and connection to a source of AC (or DC) power are indicated by additional LEDs. The receiver can be operated from the supplied AC Adaptor which provides 12 VAC power, or from a nominal 12 VDC power source. RF? GAIN TUNING 123 4 7 CLEAR 56 89 0 MEM? STORE MEM?

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. 2) 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 1 kHz steps and counterclockwise rotation decreases frequency in 1 kHz steps. The and buttons increment and decrement the frequency in 5 kHz steps. 3) Program Buttons 0 - 9 Numeric buttons - Permit direct entry of receive fre- quency in kHz from 100 to 30000 kHz. CLEAR - Press to cancel an entered frequency and restore the previously displayed frequency or to exit the memory mode. ENTER - Press after entering the desired operating frequency for immediate tuning to the entered frequency. Also, press after entering a MEMORY channel number to store the channel in a MEM STORE operation. - Press to turn the receiver On or Off. The frequency readout will be displayed when the receiver is on. - Press to toggle the display brightness between normal and dimmer settings. MEM? STORE - Press to enter the memory store mode. The ?MEMORY MODE? LED will flash (see Item 1). MEM? RCL - Press for a memory recall. The MEMORY MODE LED will light (see Item 1). 4) VOLUME - Turn this clockwise to increase the volume setting. Turn this control counterclockwise to reduce the volume setting. 5) 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. 6) SPEAKER - This is the opening for the internal speaker of the receiver. 7) HEADPHONE JACK - This connector accepts a 1/8 stereo/mono headphone connector.

OR? ? 12 VAC? 400 mA - - - 5050 6 Installation UNPACKING - Carefully remove the SW1 and included AC Adaptor wall transformer from the shipping carton and examine them for evidence of damage. If any damage is noted, immediately contact the transportation company responsible for delivery or return the unit to the dealer from whom it was purchased. Keep the shipping carton and all packing material for the transportation company to inspect. The original carton and packing material should be retained for repackaging should it be necessary to return the receiver. Inspect the packing material for any accessories or printed material before storing the box. LOCATION - Location is not critical. For fixed locations, the SW1 should be operated from the AC Adaptor. Keep curtains and other flammable material away from direct contact with the AC Adaptor to avoid overheating the transformer which could result in failure or fire. FIXED INSTALLATION - After unpacking the unit, connect the antenna system to the appropriate antenna input. Connect 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. Plug the AC Adaptor into a source of 120 VAC, 60 Hz power. Refer to Figure 2 for the diagram of a typical fixed installation. ANTENNA REQUIREMENTS - Basic type Connect a single wire lead-in to the ?50 Ohm? screw terminal on the rear panel of the receiver. This ?lead- in? wire and antenna can simply be one end of the supplied 30 foot piece of wire. The wire can be distributed along an attic, out the window, or across the room, for example. The end that connects to the ?50 Ohm? screw terminal must have its insulation stripped back so that a good electrical connection is made between the wire and the screw terminal. Alternatively, a 50 Ohm coaxial cable feedline from a dipole, vertical or beam type antenna should be connected to the rear panel ?50 Ohm? SO-239 coaxial type antenna connector. A mating PL-259 connector on the receiver end of the coaxial cable is required, in this case. NOTE: Disconnect the AC Adaptor and antenna wire from the receiver if the unit will not be used for an extended period of time or if a weather storm contain- ing damaging lightning is likely. OPERATION FROM 12 VDC VEHICLE SUPPLY - Observe proper polarity connection between the vehicle lighter or accessory socket and the coaxial DC power plug (5.5 mm O.D., 2.1 mm I.D.) which is intended for c
