1. Loosen the housing rotation set screw.
2. First rotate the housing clockwise to the desired location. If
the desired location cannot be achieved due to thread limit,
rotate the housing counter clockwise to the desired location
(up to 360° from thread limit).
3. Retighten the housing rotation set screw.
Use of ordinary copper wire of sufficient size to
ensure that the voltage across the transmitter
power terminals does not drop below 9 vdc. To
power the transmitter, connect the power leads to
the terminals indicated on the terminal block label.
The power terminals are polarity insensitive, which
means the electrical polarity of the power leads
does not matter when connecting to the power
terminals. When wiring to the screw terminals, the
use of crimped legs is recommended. Tighten the
terminal screws to ensure adequate contact. No
additional power is needed.
