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

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.
