RESYNCHRONIZATION
If the remote sensor is lost, dashes will be
displayed. To resynchronize, press both
the °C / °F and High / Low Record buttons
at the same time for five seconds.

4.3.1 Best Practices for Wireless
Communication
Note: To insure proper communication,
mount the remote sensor on a vertical
surface, such as a wall. Do not lay the
sensor flat.
Wireless communication is susceptible
to interference, distance, walls and metal
barriers. We recommend the following
best practices for trouble free wireless
communication.
1. Electro-Magnetic Interference (EMI).
Keep the console several feet away
from computer monitors and TVs.
2. Radio Frequency Interference (RFI).
If you have other 433 MHz devices
and communication is intermittent,
try turning off these other devices for
troubleshooting purposes. You may
need to relocate the transmitters
or receivers to avoid intermittent
communication.

3. Line of Sight Rating. This device
is rated at 300 feet line of sight
(no interference, barriers or walls)
but typically you will get 100 feet
maximum under most real-world
installations, which include passing
through barriers or walls.
4. Metal Barriers. Radio frequency will
not pass through metal barriers such
as aluminum siding. If you have metal
siding, align the remote and console
through a window to get a clear line of
sight.
The following is a table of reception loss
vs. the transmission medium. Each "wall"
or obstruction decreases the transmission
range by the factor shown below.
