prong. The wide blade or the third prong is provided for your safety. When the provided plug does not fit
into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles,
and the point where they exit from the apparatus.
11. Use only the attachments/accessories specified by the manufacturer.
12. Use only with a cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid
injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as power supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or
has been dropped.

1. MEMORY BUTTON
The MEMORY button is used to store the frequency of a broadcast station. To manually store station
settings, tune in the desired station, press the MEMORY button and then a memory number 1-20, and
then press the MEMORY button again. This is a time-critical operation and it must be completed with a
few seconds.
STEREO TUNER
The MEMORY button also functions as the AUTO SCAN/Memory Store key. When depressed and held
for more than 2 seconds, it automatically scans the entire FM band memorizes the first 20 signals and
then repeats this process in the AM band.
2. PRESET BUTTON
Pressing this button and the MEMORY button simultaneously will play the memorized setting for 5
seconds.
3. MODE PRESET/TUNE BUTTON
This button selects between the PRESET mode and TUNE mode. In the PRESET mode the up/down button

4. MEMORIZED FREQUENCY SELECTION BUTTONS
This allows for as many as 20 station presets to be stored and recalled from memory.
To select channels 1-9 simply depress the desired button. For channels 10-19 simply depress number 1
and then the other number within one second. For channel 20 simply depress the number 2 and then 0
within one second.
5. VOLUME CONTROL
This determines the level of the output signal (of the variable outputs only). The level increases as you turn
it clockwise and decreases when turned counter clockwise.
6. POWER SWITCH
This switch turns the AC mains ON/OFF. When in the ON position, the power switch will illuminate.

The ability to receive an FM signal may be diminished by terrain, area buildings, and the construction
materials of the building housing the receiver. Keep these circumstances in mind when selecting the type of
FM antenna and its mounting position.
An indoor FM antenna is provided and should be suitable for most applications. Repositioning the antenna
may be necessary to identify the optimum mounting location. If greater signal strength is required, replace
the supplied antenna with a large outdoor FM antenna using 75 Ohm coax as the lead wire.

The ability to receive an AM signal may be diminished by terrain, area buildings, and the construction
