This section contains information and procedures to aid in restoring the equipment to its
proper operating condition after it has been determined that a problem exists.
The following warnings and cautions apply while operating, performance testing, trouble-
shooting, or repairing the MDR-8000 series radios.
Short circuits in low-voltage, low-impedance dc circuits can cause
severe arcing that may result in burns or eye injury. Remove rings,
watches, and other metal jewelry while working with primary cir-
cuits. Exercise caution to avoid shorting power input terminals.
XMTR and RCVR crystals are soldered and tuned in an oscillator
assembly board at the factory. Crystals are not replaceable compo-
nents.
Units with the electrostatic-sensitive (ESS) symbol contain ESS
devices. Store these units in an antistatic container when not in use,
and anyone handling a unit should observe antistatic precautions.
Refer to the Special Precautions pages in the front of the instruction
book for detailed handling information.
