So with all of that, let’s start setting up your unit. We’ll start with the remote wireless transmitter as that’s
usually what our customers want most! The big unit is the receiver (suggest you keep this in the house). The
smaller unit is the remote transmitter.
RS220 Transmitter set-up:
Loosen the screw on the back. Select channel 1, 2 or 3.
Insert 2 AAA alkaline batteries (use lithium if your area gets really really cold, like Alaska or the
Yukon).
Select °F or °C by clicking the button.
Press the “Test” button (this confirms the channel and starts the transmission function)
Re-attach the back cover
Even though the RS220 is completely weatherproof, try to locate it in a fairly protected area. Keep it out of
direct sunlight.
