C.A.S. III

You can generally expect to be able to use them for about two years. The number of transmission signals does not affect the lifetime as much as long cold periods do.

The radio components use standard button cells (type CR2032). These button cells can be stored for up to ten years (refer to label). However, the button cells should be replaced every two years in order to adhere to the warranty conditions (the manufacturer offers a 2-year warranty against leakage).

We recommend to use Panasonic batteries.

In order to remind yourself to replace the batteries in time, we recommend to change them, for example, with every vehicle inspection and/or gas inspection.

If the battery is running low (<2.6V), the control unit issues an acoustic signal (for two seconds) when triggering the radio component and the red LED of the transmitter only turns off after about 30 seconds. If one button cell is weak, it is best to replace all of them.

For further information on changing the batteries, please download our quick guide in the Support section.

If a 2-second-long signal tone is emitted by the alarm system, a taught-in accessory part requiring a battery change was actuated immediately before that. This is also indicated by a 30-second-long visual signal on wireless magnetic contacts and radio cable loops.
Occurs:

• when wireless magnetic contacts on doors/windows/hatches are opened/closed
• when remote transmitters and conversion boards are actuated (‘remote controls’)
• when the cable loop is used in the holder

If a wireless accessory sends an alert, the other button cells are probably just as old. A complete change is recommended. Please take button cells to a battery recycling centre or collection point. They can be recycled there.

The quick guide to changing the batteries is available for download in our Support section.

You can replace the batteries (CR2032 button cells) in wireless components yourself.

To change the transmitter battery in a wireless magnetic contact:

Lever open the housing at the notch on the long housing side. Take out the printed circuit board and replace the battery with one of the same type (CR2032). Ensure correct polarity when inserting the battery.

To change the transmitter battery in a radio cable loop:

Open the housing by removing the screws on the bottom. Replace the battery with one of the same type (CR2032). Ensure correct polarity and correct alignment of the rubber seal when inserting the battery.

To change the transmitter battery in a wireless remote control:

Open the housing by removing the screws. Replace the battery with one of the same type (CR2032) and ensure correct polarity when inserting.

Please make sure you don’t leave any fingerprints on the button cells when you change the batteries (this can lead to a higher self-discharge rate). Please take button cells to a battery recycling centre or collection point. They can be recycled there.
