KINETIC WAVE DISPLAY
The kinetic wave display shows the signal reception status
of the main unit. There are three possible outcomes:
Searching for signal.
Signal is secure.
No signals.
For best results:
• Place the unit away from electrical or mechanical objects.
• Place the unit out of direct sunlight and moisture.
• Do not place the remote unit more than 100 feet (30meters)
from the main unit.
• Position the remote unit so that it faces the main unit.
• Minimize obstructions such as doors, walls, and furniture.
You may need to experiment with various locations to get
the best reception.
NOTE
Signals from other household devices, such as
doorbells, home security systems and entry controls, may
interfere with this product’s signals and cause temporarily
reception failure. This is normal and does not affect the
general performance of the product. The transmission and
reception of temperature readings will resume once the
interference recedes.
Upon successful reception:
• The top line will display outdoor temperature.
• The bottom line will display indoor temperature.
NOTE
When the temperature falls below freezing, an
alkaline battery in the outdoor unit may freeze, lowering the
voltage supply and the effective range.
If no signals are received, blanks “ ” will be displayed and
the kinetic wave icon will show “ ”. Press and
simultaneously to force a 4 minute search. This will reestablish transmission and reception for the remote and
main unit.
