temperature display

The remote 

outdoor

 temperature display has a kinetic-

wave

 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

NOTE: 

JMR828A

 can also scan for max 3 different remote

SENSOR TRANSMISSION STATUS

If blanks "----" appear on the remote 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 

doing

a signal search.

Remote Sensor Signal Search:

Press [THERMO] 

and [CHANNEL] together for 2 seconds

. The

unit will search for a remote thermo-sensor signal.

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 might be having a temperature
transmission block due to signal 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. 

Low-battery

 icons should indicate that battery

power is low and the batteries require changing.

• When the temperature falls below freezing point, the

batteries will freeze. Frozen batteries will have a
lower voltage and result in a lower transmission
radius.

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

or the main unit.

TEMPERATURE TREND INDICATORS

The temperature-trend indicator show the trends of the collected
remote temperature readings for the past half hour. Arrows indicate
a rising, steady or falling trend.

Note : If the reading goes above or below the measuring
range of the remote unit (stated in specification), the
display will show "HHH" or "LLL".

HOW TO RESET THE UNIT
