Basic Troubleshooting

Important—

If changes are made to the Group Settings (how telemetry devices, 

such as Access Points and Controllers, are grouped in order to provide coverage 
for patients throughout the hospital), there will be a break in monitoring of all 
transceivers within the Group(s) being modified. Monitoring will resume when 
the new Group Settings are in place. Clinical settings will be unaffected by the 
reconfiguration.
