Logitech Harmony universal remote stuck in safe mode

Just a message to all that have problems with there Logitec remotes. My remote went into something called a "safe mode" when my partner changed the batteries while holding the power button.... I pressed every single button to try and get out of it but nothing seemed to work, (I was getting pretty frusterated, there is nothing in the manual to tell you how to fix this problem), however, I have now learnt that as you replace the batteries you need to have the number 2 button held in as you replace the last battery. This works 100% so if you have any trouble with the "safe mode" then this is what fixes it.
