请翻译“如果由于异常原因控制器不能正常工作，请取出电池30秒后重新正确装入即可”

按你的原话翻译应该是这样的
In case the controller does not work properly due to some abnormal reason, please remove the batteries. Then put the batteries back correctly again after 30 seconds. The controller will start to work.
我觉得若是在产品上的提示，不要太长，简短的写成下列句子较好。
If doesn't work porperly, try to remove batteries then put them back after 30 seconds.

If the reasons for abnormal controller does not work, remove the battery after 30 seconds into the right。

我也不知道是不是这样讲。
在网上翻的。
