Repair Procedures
Repair of this transmitter assembly normally involves module level replacement. ADC maintains an
adequate stock of replacement modules. If you have determined that a particular subassembly is defective
and that it cannot be easily repaired at your facility, please contact the ADC Costumer Services
Department. An effort will be made to provide a module on an exchange basis. It is often possible to ship
replacement modules counter-to-counter or one-day UPS/Federal Express to expedite delivery.
On some occasions it is necessary to perform component level repairs. In many cases failures can be a
result of poor connections somewhere in the system. Poor connections can generally be repaired with a
suitable, small, grounded soldering iron. A spare parts kit of standard components is available for this
translator. Please contact the ADC Marketing Department for the price and availability of the spare parts
kit. Individual components can also be ordered from the Customer Services or Marketing departments of
ADC. The fuses are standard and generally available at local parts distributors. The parts list provides
complete manufacturer's information and part number for all standard electrical components. These
components can often be obtained from local distributors. An effort has been made to select standard (off-
the-shelf) components whenever possible in the product design. Replacement of the GaAsFET transistors
in the field is not recommended unless performed by an experienced technician. It is important to realize
that each GaAs FET operates at a specific bias voltage that must be preset before the main power supply
is switched on. Failure to provide the proper bias voltage will result in rapid GaAsFET destruction. Please
refer to the ADC Warranty and Material Return Authorization procedures for additional information
concerning repair parts.
Periodic Procedures
The BTS-7010 is designed with components that require no periodic maintenance except for cleaning and
record keeping.
The amount of cleaning necessary depends greatly on the conditions in the room. While the electronics
have been designed to function well even if covered with dust, heavy buildups of dirt and insects will
impede the effectiveness of the cooling and lead to shutdown or premature failure.
When it is apparent that the front panel is becoming dust covered, the top cover should be opened and the
accumulated foreign material removed. A small, soft brush used in conjunction with a plastic wand-like
attachment on a small vacuum cleaner is an excellent way to remove dirt. Alcohol and other cleaning
agents should not be used unless you are certain that the solvents will not damage components or
markings. Water based cleaners can be used if only a small amount of moisture is used. The fans or heat
sinks should be carefully cleaned.
Occasionally check that all RF connections are secure, but be careful not to overtighten.
Data should be recorded for all meter readings on a regular basis. It is suggested that data be recorded
once each month and that it be retained in a rugged folder or envelope for the life of the equipment. A
sample format of a log sheet is included at the end of this section. Photocopies of this sheet may be used
for if desired.
