Information Cautions Do not allow this sound system to be exposed to water, steam or sand. Do not leave your sound system where excessive heat could cause damage. It is recommended that the DAB band is used for radio listening where possible since this may result in better sound quality and freedom from interference than will often be obtained on the FM band.
Mains supply The MP-53 will operate from a supply of AC 230 volts, 50Hz only. DO NOT cut off the mains plug from this equipment. If the plug fitted is not suitable for the power points in your home or the cable is too short to reach a power point, then obtain an appropriate safety approved extension lead or adaptor. If in doubt consult your dealer. The wire coloured BLUE must be connected to the terminal marked N or coloured BLACK.
