A. BATTERY COMPARTMENT: Designed for two AAA batteries

B. WALL MOUNTING: For mounting outdoors use the wall bracket.

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.

  

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:

 

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.

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

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:

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.

  

  

All functions can be read from the liquid crystal display (LCD) in 3 windows.

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.

In an open and undisturbed field the measuring values can be transmitted over a distance of up to 30 meters (100 feet). The remote sensor is 
weatherproof and can be used both outdoors and indoors.
