Welch Allyn/Hillrom-8348-004-70 H3+ LCD BEZEL CG1C by Mortara Instrument, Inc
The Welch Allyn / Hillrom 8348-004-70 is identified in the H3+ Digital Holter Recorder service parts list as the LCD Bezel, CG1C variant.
In other words, this part is the frame or surround (“bezel”) that sits around the LCD screen on the H3+ recorder (specifically the CG1C model / color/design). It’s a cosmetic and protective component of the housing assembly, helping to secure the LCD in place as well as protect the edge of the screen and maintain the device’s overall aesthetics.
