Temperature Display - Oregon Scientific JMR818WF User Manual

TEMPERATURE DISPLAY

The JMR818WF displays temperature in Centigrade (°C). A
user-select option lets the user choose between indoor, outdoor
or alternating displays.
indoor temperature display
outdoor temperature display
To display either the indoor, outdoor, or alternating
temperature displays:
• Press THERMO to alternate between the temperature displays.
Note: The alternating display will alternate between the
indoor and outdoor display about every 9-seconds. The IN
and OUT symbols will flash to indicate that the unit is in
the alternating temperature display.
The outdoor temperature display has a kinetic-way display.
The kinetic-wave display shows the signal-receiving status by
the main unit. The are three possible forms.
The unit is in searching mode.
Temperature readings are
securely registered.
No signals
SENSOR TRANSMITION STATUS
If blanks "----" appear on the outdoor temperature display of the
main, then the unit is not receiving a signal from the remote
thermo sensor. The user may be able to receive a signal by
forcing a signal search.
To force a remote sensor signal:
Press and hold [THERMO] for 2-seconds. The unit will search
for a remote thermo-sensor signal.

Search mode will last for 67-seconds. If the unit still cannot
receive a signal, check the batteries to ensure they are properly
installed and have ample power. Try repositioning the units as
they may be having temperature transmission block as a result of
interference.
Note:
Reasons for not receiving a signal from the remote thermo
sensor may include:
1. The batteries of the remote sensor, the main unit, or
both may be low. Battery-low icons should indicate that
battery power is low and the batteries require changing.
• When the temperature falls below freezing point, the
2. The transmission range is too far.
• Shorten the distance.
3. The transmission path is cluttered with obstacles and
interference.
• Shorten the distance or reposition the remote sensor
HOW TO READ THE PRESSURE TREND
The JMR818WF gives a pressure trend for the last hour. As
illustrated below, a rising trend (arrow) indicates improving
weather. Deteriorating weather conditions are indicated with a
falling trend (arrow).

WEATHER FORECAST FUNCTION
The JMR818WF detects barometric pressure changes and displays
the illustrated weather symbols that indicate weather forecasts
for 12 to 24 hours. The radius of the forecast is approximately
30 - 50 km.
