Secware_Tech6 Posted September 17 Share Posted September 17 You can usually change them yourself but it is usual the batteries are replaced every 2 years on the service. Care needs to be taken as you can easily damage them if opened incorrectly. Also you may breach your service agreement Quote Link to comment Share on other sites More sharing options...
