the Receiver Unit is situated near an available AC electrical

outlet. Make sure all devices are turned o before beginning

installation.

Note: If you are using surface cabling, ensure you have

enough Category 5e unshielded twisted pair (UTP) network

cabling to connect the Host Unit to the Remote Unit’s loca-

tion, and that each end is terminated with a RJ45 connector.

The cabling should not go through any networking equip-

ment (i.e. router, switch).

If you are using premises cabling, ensure that the Category 5

unshielded twisted pair (UTP) network cabling between the

Host Unit and the Remote Unit has been properly terminated

in a wall outlet in each location and there is a patch cable

long enough to connect the Remote Unit and the Host Unit

to their respective outlets. The cabling should not go through

any networking equipment (i.e. router, switch).
