Why does the radio communication stop working?
By default, when the ADVC controller enters the low power state the radio will be disabled after a programmable delay. To modify this setting such that the radio is not disabled, set the holdup time to 0. This may be modified from the front screen or via the WSOS software. To modify from within WSOS, open the switchgear file (or create it if necessary) click on Display > Radio Voltage > set the Holdup time to 0.
