• Plug the speaker cable into the shortest cable of the main harness (the cable closest
to the wire tie). Tuck the cable behind the ground-wire stud. Ensure that the speaker
cable is positioned in the channel.
• Route the printer ground wire through the channel on the printer housing.
• Secure the main harness to the bracket on the bottom housing using a tie wrap.
Position the tie wrap just below the tie wrap on the main harness. Use the tie-wrap
tool, with the torque at 5 INT, to secure the tie wrap.
• If your model has an extended chassis, orient the insert so that, when installed, it is
flush with the panel that contains the power button.
When replacing the bottom housing
Note The bottom housing and extended bottom housing must be replaced by a
Welch Allyn service center to ensure proper labeling.
