NEVER connect the unit to an AC outlet or to a DC power

supply that uses more than 33 V (FP-561) or 16 V (RD-200).

Such a connection could cause a fire hazard and/or electric.

DO NOT expose the unit to rain, snow or any liquids.

DO NOT reverse the polarities of the power supply when

connecting the unit.

DO NOT apply an RF signal of more than 20 dBm (100mW)

to the antenna connector. This could damage the unit’s front

end.

Be sure to include the following four points when ordering

replacement parts:

1. 10-digit order numbers

2. Component part number and name

3. Equipment model name and unit name

4. Quantity required

Addresses are provided on the inside back cover for your

convenience.

1. Make sure a problem is internal before disassembling

the unit.

2. DO NOT open the unit until the unit is disconnected from

its power source.

3. DO NOT force any of the variable components. Turn

them slowly and smoothly.

4. DO NOT short any circuits or electronic parts. An insulat-

ed turning tool MUST be used for all adjustments.

5. DO NOT keep power ON for a long time when the unit is

defective.

6. READ the instructions of test equipment thoroughly

before connecting equipment to the unit.
