Issue
Display unit
Radio controlled clock
does not receive signal
Remote sensor is not
being received
Reposition the device. Preferably near a window and leave it there overnight.
Perhaps an additional turning of the device by 90° would help.
Replace batteries (in both devices!)
Check the position of the sensor
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!

Symptom Solution
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.
