WARNING
The VM22A must only be powered from one of the
AC Power Adaptor(s) supplied with it.
For markets where the VM22A is not supplied with a suitable AC Power
Adaptor, a Safety Extra Low Voltage (SELV), Limited Power Source (LPS)
rated AC adaptor meeting the requirements of IEC 60950 (or the local
equivalent) with a regulated 12 V, 0.5 A output rating may be used.
Under no circumstances can the VM22A be operated from the AC Power
Adaptor supplied with FastVu. Connection of the VM22A to the AC Power
Adaptor supplied with FastVu will invalidate the safety approval for both
FastVu and VM22A and may represent a safety hazard.
