Replacing the Fuse

The 5A fuse located at the back of the processor unit protects the system from overcurrent and internal fault. If the
power cannot be turned on, check if the fuse has blown. If it has blown, find out the cause before replacing the fuse.
If it blows again after replacement, contact your dealer for advice.

Replacing the Battery

The PCI-951 circuit board in the processor unit contains a lithium battery which preserves data when the power is
turned off. When the voltage of the battery is low the time is wrong, all default settings are restored, etc. When this
occurs, have the battery replaced by a qualified technician, at your earliest convenience.
