== Safety == '''Warning: the PC-MM and PC-CM contain a mains switch-mode supply and a CRT. Both hold dangerous voltages after the mains lead is removed.''' * Unplug the monitor and discharge the tube before working inside it; see [[CRT Discharge Procedure]]. * On the PC-CM, Amstrad marks the power supply area as isolated and tells engineers to take measurements in the supply circuit with reference to the top of C505, "in order to keep the chopper circuit oscillating".<ref name="sm" /> * Fit fuses of the same rating: both monitors use a 3.15 A time-lag mains fuse.<ref name="sm" /> * After working on a monitor, Amstrad's safety test is a 3 kV flash test between the joined mains live and neutral and every accessible metal part, and an insulation resistance of at least 4 MΞ©. Amstrad tells engineers to repeat these tests whenever there is doubt about continued electrical safety.<ref name="sm" />
