The radio keys are particularly energy-saving and have a battery indicator light. The battery is sufficient for approx. 50,000
operations. Check the battery indicator light regularly to avoid failure. To change the 3- or 4-channel radio key battery, follow
the steps below:
1. Carefully open the radio key housing with a coin (3-channel radio key) or a narrow object, e.g. a slotted screwdriver
(4-channel radio key).
2. Push out the battery.
3. New battery (type: CR 2032). The plus symbol must point upwards.
4. Press the radio key housing together again.
