11.5. Error alerts
Battery low
The warning shows that the battery on the CPU board is exhausted or not inserted. The
function of the battery is powering the real time clock when the frame is powered down.
The low battery does not affect normal operation of the matrix. However the error log will
not have correct time stamps.
Switch off the matrix and take out the MX-CPU2 board. Locate the battery holder (see
picture below). Check if the battery is contacting well in the holder.
Take the battery out firmly taking care not to bend the spring contact upwards. Bend the
spring contact a little bit downwards to ensure good contact.
If the battery is exhausted, replace with lithium button battery type CR2032.
