Maintenance

Inside the matrix there is a battery to store the date and time when the matrix is switched off. If it has to be
replaced, open the cover as described in section 2.3.1 Opening the matrix, page 12, with the matrix
switched off.
Replace with a CR1225 battery (or equivalent DL1225, ECR1225, BR1225, DL1225B, BR1225-1W,
CR1225-1W, KCR1225, LM1225, 5020LC, L30).
