To manually set the clock:

1.Press [CLOCK] and hold for two seconds. The hour will start to flash.

2. Enter the correct hour using the [TEMPERATURE DISPLAY ] button. Hold to rapidly increase the value.

3. Press [CLOCK] to confirm and proceed to set the minute. Again, use the [temperature display ] button to select the correct minute.

4.Press [CLOCK] to proceed to set the year, month, day and language for day - of - week.

5.When finished, press [CLOCK]. The time and date are now set.

6.To select the U.S. time - zone, press [ZONE] to toggle among Pacific(P), Mountains (M), Central(C) or Eastern (E).

TEMPERATURE DISPLAY

This unit displays temperature in °C or °F

temperature display

The remote outdoor temperature display has a kinetic-wavedisplay.

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 temperature channels. To do so, simply press the CHANNEL button once to switch to the different channel.

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-batteryicons 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.

HOW TO RESET THE UNIT

Press [RESET] to return all settings to the factory values.

The button is used when the unit is not operating in a favorable way, such as in the rare case of a malfunction.

HOW TO WALL MOUNT OR

USE TABLE STAND

MAIN UNIT

Flip the table stand open to place the unit on a steady, flat surface. Or use the recessed hole on the back to mount it on a wall.
