The internal line impedance must not exceed max. 0.8
Ω
.

it must be ensured that radiation release is blocked (see “Demo mode –
Operation without radiation release” on page 1-13).
Software version The overall system software version is determined by the software statuses of
the EEPROMs on the boards (see “List of software versions” on page 1-16).
Wireless phone interference with
medical electrical equipment To ensure safe operation of medical electrical equipment, the use of mobile
wireless phones in practice or hospital environments is prohibited.
Disposal The X-ray tube assembly contains a tube with potential implosion hazard,
a small amount of beryllium, a lead lining as well as mineral oil.
Error messages Error messages are displayed on the single-line display of the Multipad
(XG 5 / 3 / 3 PPE) or on the touchscreen of the Easypad (XG
