Section 7 — Disassembly
Before You Begin
Opening a monitor and breaking the quality seal can void your
manufacturer warranty! Contact the Criticare Service Department
before you break the seal on any monitor.
The following procedures are intended to be used by qualified
biomedical engineering or field service personnel for replacement of
PCB assemblies. These procedures are not intended to be used for
component-level trouble shooting and repair of the PCB assemblies.
The repair procedures for the 506N3 Series monitors are included
here for the determination of damaged or unusable assemblies. The
manufacturer does not recommend attempting field repair of the
printed circuit boards.
Also see the 506N3 Series Final Assembly Drawings in Section 9.
Service Safety
• The following procedures require working with exposed
electrical circuits. Repair should only be attempted by
experienced electronics technicians.
• Do not short circuit the battery terminals! The resulting high
current discharge can cause burns.
• Before disassembly remove the battery to avoid electrical shock.
• Electronic components are selected for specific performance
characteristics. Use of substitute replacement parts may cause
inaccurate performance or damage to the monitor. Order
replacement components by their catalog or part number from
your authorized dealer.
• Any time an electronic circuit board is altered through repair or
adjustment, it must be fully tested before use.
• Replacement of surface mount components is beyond the scope
of this manual. Attempting to remove surface mount
components with a soldering iron can result in the overheating
of the board and damage to tracings. Damaged laminated circuit
boards cannot be repaired and require replacement.
• Any electronic repair should be done in compliance with ANSI/
IPC–A–610 manufacturing standards for medical equipment.
Failure to use standard ANSI/IPC assembly practices can result
in permanent damage to the monitor.
