Disassembly Procedures (A1)
68 Chapter 6 - Disassembly Guide
Caution During reassembly, pay particular attention to the polarity
of the battery cable before reattaching. The polarity is
marked on the circuit board. Red connects to the +ve
terminal, black connects to the –ve terminal. If battery cable
polarity is reversed, it is likely that circuit damage will
occur.
7. Unscrew the NiBP Luer connector.
During reassembly, preload the NBP Luer connector by twisting the
silicone NBP tubing in opposite directions prior to making the Luer
connection. This prevents disconnection.
Front and rear case assemblies are now completely separate from one another.
Front Case Disassembly Procedures
This section describes how to remove/replace items from the front case
assembly. First separate the front and rear assemblies as described in the
section “Separation of Front and Rear Case Assemblies” on page 78.
Procedure to remove the main PCB assembly from the front case
assembly:
1. Use a Phillips-head screwdriver to remove the screw holding the main
PCB assembly in place in the front cover assembly.
For reassembly, note the two guides in the cover and the corresponding
two notches in the PCB.
