3. SET-UP

Setting-up the JKBA-1 is very easy. Just follow the steps below.

1- Activate the batteries in the remote sensor

2- Position the remote sensor in the same room in a radius of about 1 meter to the display unit.

3- Activate the batteries in the display unit: First a full segment display will appear on the LCD for about 3 seconds.

4- Then the sea level setting (0m) will blink on the display. You now have 8 seconds to begin setting your local sea level using the +/-

buttons. When you have reached the desired height wait 8 seconds, then the device will start receiving data from the remote sensor and

then the time from the time signal transmitter DCF77. Wait until all data (time and temperature) are indicated correctly on the device.

That is all you have to do! From now on your device will function without you ever having to push another button.

In chapter 4 you will find details for optional settings and also information on certain procedures.

4. EXTENDED OPERATION

All operations on the device are carried out by pressing buttons. It is very important that you read chapters 2 and 3!

In these chapters you will find additional information about the functions

4.1 Weather forecasts

This Irox device uses a high quality pressure sensor to measure barometric pressure and the respective changes. This information is then, using a by meteorologists specially developed algorithm, used to calculate a weather forecast for the coming 12-24 hrs. Eight different forecasts are possible:

Sunny Slightly cloudy

Cloudy Rain Heavy rain

Snow Heavy snowfall

Thunderstorms

/Stormy

COMMENT: These calculated weather forecasts have a reliability of approx. 70%. The forecast is displayed, not the current weather. SUNNY means clear weather day and night.

4.2 Air pressure indicator

The indication of the air pressure depends on the setting of the sea level.

If the setting is 0 meters, you will see the local measured pressure. This value is based on the factory calibration of the pressure sensor.

If you have programmed the height above sea level of your location you will see the barometric pressure measured at your location, calculated from the local pressure measured and the set height above sea level. With this value you can meteorologically position your location with other available information (e.g. the isobar map on TV, Internet or in your daily newspaper).

With the height adjustment setting you can also adjust any slight deviations to a precision measuring instrument and so to say calibrate the pressure sensor. As a rule: 5m more in height, pressure reading is increased by 1 hPa.

4.3 Trend indicator

You have a total of 4 different trend indicators available, 2 of them simultaneously:

1- The large Weather Icon on the upper right of the display shows the forecast for the next 12-24 hrs. On the left side of that, underneath the pressure indicator, you will see a smaller icon with 3 arrows. The small icon indicates the forecast 12 hours before, thus giving you additional information regarding the forecast development.

2- Graphic pressure history

- One bar equals 1 hPa. This displays the pressure history of the past 24 hours.

- If you change the pressure units (from hPA to inHG), the graph will remain the same. The only thing that vanishes is the scaling on the

right side of the graph with the -4 to +4 hPa.

- The graph can be displayed in 3 different ways:

Dynamic stacking bars, increasing from -24 hrs. to 0 hrs.

Static stacking bars, only the 0 hrs bar blinks

Static line diagram, only the segment 0 hrs blinks

4.4 Temperature / Moisture

The display unit measures the temperature and relative humidity and receives additional measurements from the remote sensors included in the delivery. The temperature can be displayed in °C or °F.

The comfort zone is calculated from the thermo/hygro measurements of the display unit.

A frost warning is programmed on the remote sensor. When the temperature measured by the remote sensor drops below 3°C, the frost warning icon will appear on the display.

SEARCH FOR REMOTE SENSOR

You can start the search for the remote sensor manually by pressing and holding the SYNC button for 3 seconds. The wave icon will start to blink.

The wave icon indicates the receiving status of the remote sensor signal:

Icon Status

Searching for the remote sensor signal

Sensor signal successfully received

No signal received for over an hour

With this search procedure the device searches the same sensor that was already previously logged in. If you replace the batteries in the sensor, the sensor gives itself a new code and will then no longer be recognized by the display unit. You can resolve this problem by:

- removing the batteries from the display unit and replacing them with new ones

or

- if the batteries are still O.K., repeating the logging in procedure as described above by pressing and holding the SYNC button and while

the wave icon is blinking press and hold the SYNC button again for 3 seconds. The temperature indicator will start to blink indicating

that a new sensor is being searched for and will be logged in.

INDICATION AND CONDITIONS OF THE COMFORT ZONE

The COMFORT ZONE is indicated for the room where the main device is positioned. The COMFORT ZONE is a function regarding temperature and rel. humidity. There are 5 conditions COMFORT, WET, DRY, HOT and COLD.

4.5 Time function

The time signal DCF 77 is transmitted by the atomic clock in Mainflingen near Frankfurt/Main. The long-wave transmitter has a range of up to 1500km.

If the time icon is displayed without waves you have reception problems. Please observe following points:

- There are fewer disturbances in the atmosphere during the night which increases the likeliness of reception. One reception per day is

completely sufficient to ensure the preciseness of the clock by +/- 1 second

- Make sure that the device is at least 2 meters (8 feet) away from possible sources of disturbance such as TV, computer, monitor,

microwave etc.

- In rooms with concrete or metal walls (e.g. cellar rooms, modern office buildings etc.) the receipt of the signal may be more difficult due

to the shielding. In such cases find a better location for the device near a window. Sometimes it also helps to simply turn the device by 90°,

thereby improving the alignment of the receiving antenna.

Caution: During the setting procedure as described below you will exit the setting mode if more than 1 minute passes between pressing the buttons. The settings already made up to this point will then be deleted. To prevent this from happening each setting must be completed.

RADIO CONTROLLED CLOCK RECEIVING LOGIC

1. As described in chapter 3 the time transmitted by the time signal transmitter DCF77 is automatically received when the batteries are

activated. The time signal reception takes about 3-10 minutes. During receiving the icon will blink, if reception is good with waves if

reception is poor without.

2. If you would like to switch the automatic time reception off and then on again you can do so with the “setting”.

3. During normal operation an automatic time reception will be activated daily at 0:00, 3:00, 6:00 and 12:00.

4. As soon as the device has received a signal the time will be correctly adjusted and the icon is active.

5. If reception is poor the icon will be displayed. You may then set the clock manually at any time. The next reception attempt will then be

activated during the night.

SETTING

You can choose between two operating modes for the clock:

1- Radio controlled clock with regular time comparisons. In between the active receptions the time runs on integrated quartz (this is a

factory setting which is reactivated after every battery replacement)

2- Strictly as a quartz clock

Move to set mode with the SET TIME button (press and hold for 3 seconds). “On” will appear in the time display. This means the radio receiving is activated.

With the +/- buttons you can make changes to the setting, with the SET TIME button you move to the next setting.

The setting options vary depending on operating mode "On" or OFF"

Operating mode 1 – Radio controlled clock on = On

- Time indication format: 24 hours or 12 hours resp. AM/PM

- Time zone setting (standard =0, adjustable from -9 to +9 hours):

Time deviation as compared with the received radio time as the respectively valid time in Central Europe (Germany, France, Switzerland,

Denmark etc.). If you set a time zone “ZONE” and the accordingly corrected time will appear on the time display. This is ideal for

locations where the DCF77 time signal is received but that have a different time such as Great Britain (-1HR) or Finland (+1HR)

Complete the setting with the SET TIME button

Operating mode 2 – Radio controlled clock off = OFF

- Time indication format: 24 hours or 12 hours resp. AM/PM

- Setting the hours

- Setting the minutes

We recommend this operating mode for locations where the time signal can not be received. Switching off the receiver spares the batteries.

Also please check the following before contacting the customer service of the store where you purchased the device:

Issue

Display unit

Symptom

Radio controlled clock does not receive signal

Solution

Reposition the device. Preferably near a window and leave it there overnight.

Perhaps an additional turning of the device by 90° would help.

Display unit/

Remote sensor

Remote sensor is not being received

Replace batteries (in both devices!)

Check the position of the sensor. Read the details explained below.

Start sensor search with the SYNC button (press and hold for 3 seconds).

If this is not successful repeat and while the waves above OUT are blinking press and hold SYNC button for 3 seconds again!

Information regarding transmittal from remote sensor to display unit

• It is very important that you activate the batteries in the remote sensor BEFORE activating the batteries in the display unit. As soon as the

batteries are inserted in the remote sensor it will begin sending thermo measurement data. The display unit will start receiving data as soon

as its batteries are activated.

• Before mounting the sensor at its final position we strongly recommend ensuring the successful communication, which means checking the

data on the display unit. To do so place the sensor within a radius of approx. one meter of the display unit. Make sure there are no sources

of disturbance in the vicinity of the two devices.

• As soon as the measurement data appears on the display unit you may mount the sensor within the maximum distance of 30m at a position

of your choice.

REMARK:

• Before operating the device wait until data from the sensor appears on the display unit!

• The effective receiving radius may be limited by building structures (e.g. reinforced concrete walls), metal surfaces or grates, electronic

devices as well as the position of the sensor and/or the receiver.

Placement of the sensor and the display unit

• Place the sensor so that the back or front side is facing the receiver. If possible avoid shields or disturbances in the line of transmission.

• The remote sensor is weatherproof. Avoid direct sunlight, rain, or snow. Preferable are measuring points in the shade, for example under a

weather protected roof with good air circulation.

• The remote sensor can be stood or mounted vertically on a wall. To do so please use the provided wall bracket, this should be mounted on

the wall with a screw not with a nail.

• Ideally the sensor should be placed 1.25m (4 feet) over the ground respectively grass surface. Stone, asphalt, or tar surfaces can become

extremely warm and thus falsify the measurement.

• Heat sources such as a fireplace or heaters of any type must be avoided.

• The display unit must be positioned within the transmitting radius of the sensor and away from the direct influence of heating or cooling

apparatus. A distance of at least 1 meter must also be maintained between sensor and display unit and other remote equipment. Remote

equipment is, for example, cordless telephones, wireless headphones, baby monitors, mobile phones etc.

6. BATTERY CHANGE

: BATTERY CHANGE INDICATOR

The batteries last for about 8-12 months. Depending on the batteries used this time frame may be a bit shorter or longer. A battery icon will appear, to prevent an undesired and unexpected interruption of operation.

- Battery icon in the temperature window

This means that the batteries in the remote sensor need to be replaced

- Battery icon in the clock window

This means that the batteries in the display unit are becoming too weak and must be replaced.

Important:

Use only new batteries and never combine old batteries with new batteries. Observe polarity when inserting batteries!

Please also remember that used batteries do not belong in domestic trash, they should be disposed of at designated collection points.

Our environment will appreciate it!

Important note on batteries

• The JKBA-1 is delivered with batteries so that you can immediately put it into operation. These batteries may not last as long as store

bought batteries. As soon as you have to replace the batteries in the remote sensor we recommend using alkaline batteries. Especially when

outdoor temperatures drop to 0°C (32°F) or below these batteries will ensure a more reliable transmittal. If possible even use lithium

batteries.

• Never use rechargeable batteries. The output of rechargeable batteries is often not sufficient for our devices.

7. CARE OF THE DEVICE

- Do not expose the device to extreme temperatures or direct sunlight over longer periods.

- Avoid blows and shocks of any kind to the device.

- For cleaning use a dry soft cloth that you have moistened with water and a very mild cleaning agent. Never use volatile substances such as

benzene, thinner, cleansing agents in spray cans etc.

- When the device is not being used store it in a dry area and out of the reach of small children. In such cases it is important to remove the

batteries!

- If the device is activated under extreme coldness it may occur that the display becomes illegible. As soon as it is returned to a warm

environment the device will function normally again.

- Please keep the Instruction Manual and other documents delivered with the device stored carefully so that you can reference them at a later

point if necessary.

- Important: All disposal fees in Switzerland (vRG) as well as in the EU (WEEE) for all Irox devices are covered.
