Installation of remote sensor
14 Locating remote sensor in clear areas can attain a maximum lOO-foot transmission distance, Actual
transmission distance may be reduced by interference from building, obstructions or a screen between the
sensor and the receiveri Location should be away from direct sunlight and sheltered from rain.
Checking sensor transmission
1. The red LED on the sensor will blink for each RF temperature transmission The sensor is designed with a
battery saving mode,
2, When updated temperature signal is successfully received by the receiving uniti Towei icon will blink and
the new temperature of that particular channel will be displayed.
3. If you note the “Solid” dash (--- F) display for one channel atter l 1 minute registration, the signal has been
lost, Try rotating that sensor in 45 degree steps, waiting at least 3 minutes after each position change.
Observe the receiver channel display at each position to determine that the remote temperature display has
been restored. If not, continue rotation or repositioning of both receiver and remote sensor until reception
is observed.
