The WiFi module is an option on the Trio II and may have been supplied by the utility provider or network operator. When the System Status screen shows the WiFi symbol in red or amber, then this means one of the following:

• The monitor is out of range of the WiFi network or it is not available – try moving closer to the access point or router
• The security details for the configured WiFi network have changed since they were setup
• The monitor’s details have been actively blocked by the WiFi network
• The monitor is running on batteries – the WiFi module does not function when running on batteries
