Step 5: Troubleshooting & FAQ
What do I do if my PositiV® system shows no connectivity or signal strength?
Reevaluate the installation locations. Ensure the line of sight is as clear as possible
and the distance between the units is minimized. If required, identify new installation
locations and reconfigure the devices.
What do I do if my PositiV® system does not show up when I open the Melink PositiV®
app?
Verify that Bluetooth is enabled on your phone. Then, close and reopen the app. It
may take up to a minute for the PositiV® units to appear on the app.
Is it necessary to install the outdoor unit on the roof?
It is not necessary but recommended. If there is an installation location on the
exterior of the building that meets all outdoor unit installation requirements, then it
can be installed there.
