Servicing Notes
4-2
When reconnecting, align the flex carefully in its receptacle, making
sure it is both centered from side to side in the connector, and oriented
at 90 degrees to the connector.
Be sure the flex is fully seated in the connector and the connector is
properly latched.
Flex Circuit Handling
The flex circuits are delicate and can be damaged by improper handling:
Do not bend sharply.
Do not scrape the contact surface against other parts.
Handle the flex with bent tip needle nose pliers whose jaws are cov-
ered with a soft material (such as plastic tubing or tape).
Internal Connections
Whenever troubleshooting indicates a particular PCA may be at fault, it is
always good practice to check all the connections to that PCA carefully before
replacing the PCA.
Cable and Assembly Placement
How the wires and cables are routed and dressed inside the chassis plays an
important role in two areas: in preventing long term wear problems, and in
reducing electromagnetic and radio frequency interference emitted by the
defibrillator.
When you disassemble any part of the defibrillator, pay special atten-
tion to how cables and wires are routed.
When you reassemble the defibrillator, be sure to route and dress all
cables and wires as they were originally.
Return all components to their former position within the case.
Instrument Reassembly
If you do not reassemble the instrument correctly, the instrument may no
longer be properly sealed. This could result in water damage to the defibrilla-
tor. Be sure to maintain the water-resistant seal by:
Replacing all gaskets in their proper locations.
Correctly assembling all parts that mate with gaskets (making sure
the gaskets are not wrinkled or pinched).
Replacing all screws.
Making sure that screws are not cross-threaded and that they are
tightened firmly.
