M4735A Service Manual 1-3
Overview

Repair Philosophy
Defibrillator/Monitor
The repair philosophy of the M4735A is subassembly replacement. Examples
of subassemblies are the printer, the Control Printed Circuit Assembly (PCA),
and selected connectors and other items. Repairs that involve replacing com-
ponents on a PCA are not supported.
CAUTION Individual component replacement should not be attempted outside of a fac-
tory authorized repair facility. Component level repair is extremely difficult
due to the extensive use of surface mount technology and the high parts-den-
sity on the circuit boards. Unauthorized component replacement can impair
performance of the M4735A.
Batteries
The repair philosophy for the SLA battery (M3516A) is unit replacement. If a
battery fails, it is replaced, not repaired.
For information on ordering replacements, see "Supplies & Accessories" on
page 5-21.
