Installing or Replacing the Optional Recorder Assembly
Note:
Unless purchased separately for a monitor already in the field, the recorder option is installed at the
factory. Order an upgrade from your local Sales Representative.
The recorder option consists of two components: the recorder module and the recorder CPU PCBA.
The recorder CPU PCBA and recorder module fit into the upper slot on the monitor’s left side (refer to Figure 4-
1). The recorder CPU PCBA must be installed first, followed by the recorder module. Refer to Table 1 on page
6-1 for the recorder CPU and recorder assembly part numbers.
Installing the Recorder
Warning:
A safety hazard is created if the mylar insulator is not properly installed over the recorder CPU
PCBA.
1 Power OFF the monitor.
2 Remove the printer “dummy panel” by removing the screw located in the top portion of the battery
compartment.
3 Remove the recorder hold cover and insert the recorder CPU into the connector located at the bottom of the
recorder compartment.
4 Tighten the thumbscrew to secure it to the bottom of the recorder compartment after fully inserting the PCBA
into the connector.
5 Install the insulator sheet between the bottom of the printer and newly installed recorder CPU PCBA.
6 Insert the recorder assembly, ensuring that it fully engages the connector at the back of the recorder
compartment. Press the release bar to open the recorder assembly and tighten the two phillips-head screws
located at the rear of the recorder.
