You will have to call Bell Express Vu and se a flip flop option since you are using receiver both at the cottage AND home...both locations can not be active at the same time
When you're at the cottage call 1-866-395-9994
They will ask you to go to MENU 6-1-1 to make sure that you, first of, get signal. Then they will ask you to press CANCEL once, then 3. This will bring the system info on screen. They will ask you the receiver number, and if any other receivers will be used at the secondary location.
They will then deactivate all reeivers that are at home, and when you will leave the secondary residence you will have to call them for them to deactivate the cottage and activate the home.
