Troubleshooting
General fault isolation
Visual inspection
A thorough visual inspection of the equipment can save time. Small things—
disconnected cables, foreign debris on circuit boards, missing hardware, loose
components—can frequently cause symptoms and equipment failures that may
appear to be unrelated and difficult to track.
The following steps might seem trivial but it is highly recommended that they be
performed to remove these “simple” failures as causes of problems.
NOTE
Notify the staff and move any admitted patients off the receiver system or
provide for alternate monitoring before removing power from it.
Set the ON/OFF switch to the
OFF
position and disconnect the Receiver System
from its power source.
Perform an internal visual inspection of the components.
Take the time to make all the recommended visual checks (refer to the visual
inspection table below) before starting any detailed troubleshooting procedures.
Area
Look for the following problems:
I/O Connectors and
Interface Cables
Fraying or other damage
Bent prongs or pins
Cracked housing
Loose screws in plugs
Excessive cable tension or wear
Secure mounting hardware
Internal Harnesses
and Cables
Excessive tension or wear
Loose connection
Strain reliefs out of place
Circuit Boards
Moisture, dust, or debris (top and bottom)
Loose or missing components
Burn damage or smell of over-heated components
Socketed components not firmly seated
PCB not seated properly in edge connectors
Solder problems: cracks, splashes on board, incomplete feedthrough, prior modifications or repairs
Ground Wires/Wiring
Loose wires or ground strap connections
Faulty wiring
Wires pinched or in vulnerable position
Mounting Hardware
Loose or missing screws or other hardware, especially fasteners used as connections to ground
planes on PCBs
Receiver System mounted loosely or near vibration
Power Source
Faulty wiring, especially AC outlet
Circuit not dedicated to system
(Power source problems can cause static discharge, resetting problems, and noise.)
