Disassembly Procedures (A3)
78 Chapter 6 - Disassembly Guide
Procedure to remove recorder:
1. Press the
Paper Eject
button on the right side of the recorder. The door
drops forward.
2. Remove the paper roll, if installed. Two fastening screws are visible on
the back panel of the recorder.
3. Use a screwdriver to back out the captive fastening screws.
4. Pull the recorder straight out of the side of the monitor, disengaging the
connector at the rear of the module from the recorder PCB in the
assembly.
Note that removal of the recorder PCB can be accomplished only after
the front and rear cases are separated.
Separation of Front and Rear Case Assemblies
Procedure to separate front and rear case assemblies:
1. Remove handle as indicated in procedure on page 77.
2. Use screwdriver to remove four screws fastening Rear Case Assembly to
Front Case Assembly to Front Case Assembly. Retain for reassembly.
Note that the gasket must be inserted around the top of the rear case
before reassembly.
3. Separate the two major case assemblies. There is enough cable and
tubing slack to permit the two assemblies to remain at an angle of
approximately 90 degrees to each other.
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.
