it calls for the manager after it realises there's no tokens coming out (counted from £6 down to £4)... usually by pressing loads of buttons and opening doors in a random order clears it - but since taking those pics earlier I've not been able to stop the alarm going off when I switch it on. Keeps saying call manager

any ideas? when I open the door the alarm stops but if I try the TEST button the alarm sounds again
seems like you need to be a magician to figure these things out!
