CE680L is set to auto mode and CE680R is set to remote mode. 

What will happend with CE680L if the connection to CE680R (Remote mode) lost? 

Will CE680L be automatically switched into the “Auto/Local” mode or remain set as “Remote” with blocked local control? 

If there will be a temporary power outage on the Receiver side, which operating mode will be set up on the CE680R after it’s reboot? 

When the connection of the "Link" is lost, the "Remote Unit" stays on "Remote Mode",and the "Local Unit" stays on "Local Mode".

If there is a temporary power outage on the Receiver side, after the power is restored, the "Remote & Local Units" will be on "Auto Mode".
