SO-5000 Ophthalmic Microscope

CONNECTING TO A POWER SOURCE

The Scan Optics Ophthalmic Microscope may be connected to either an earthed mains (90-260V) ac
supply, or a 12V dc supply, or both. The power supply will automatically select the correct mains
voltage. If both ac and dc supplies are connected, the dc supply (for example, a 12V battery) will act
as an emergency backup for mains power. In this case, the microscope will not run from battery
power unless the mains supply fails or falls by more than 20 percent, or is switched off. If mains
power is restored, the microscope will resume using mains power automatically. The mains power
switch on the microscope does not switch the battery off. Refer to figure 6.
