The used batteries must not be discarded, but should be disposed of in
accordance with the existing rules for environment protection.
When the device indicates low battery, the battery must be replaced.
When replacing the battery, wait about 1 minute between removing the old battery and
installing the new one.
After battery replacement, the device will inform the controller / control panel about its status
during periodical communication. As a result, the information might be sent with delay whose
duration depends on the frequency of periodical communication (if the “ECO” option is
enabled, it can take up to 3 minutes).
