2. Press to select Show Info. The Show Info screen appears.
Make sure the Firmware version reported by the radio card displays a version release
number. If the monitor displays “Version not found,” wait for this field to change to a
version number. This change indicates that the radio and monitor are communicating.

Set the NetName on a Propaq LT monitor
Use this procedure to change the network name assigned to the monitor (assuming that
the current network name is one of the pre-set names listed in the monitor Net Name
menu). To set a custom network name, see “Set an SSID using the radio configuration
tool” on page 14.
WARNING Do not attempt to change the network name unless you are a
qualified biomedical service engineer or a Welch Allyn employee. Changing the
monitor network name causes the monitor to re-start and seek to connect with
the FlexNet network corresponding to the new name.
WARNING Change the network name in a non-clinical environment only.
To change the network name
1. Enter the Service menu.
2. Highlight Radio and press .
3. Highlight NetName and press . The NetName screen appears.
4. Highlight another network name.
Simultaneously press and and hold for one second. The monitor shuts down,
losing all stored patient data, and then restarts.
If the current network name is a custom name, the monitor displays something
similar to the following screen:
You cannot change a custom network name using the Net Name menu. Press to
return to the Service Menu. To set a custom network name, see “Set an SSID using
the radio configuration tool” on page 14.
