INTRODUCTION Congratulations on purchasing this Digital Radio Tuner from Cambridge Audio. It is the r esult of an extensive Research and Development program undertaken to identify the circuitry and components fundamental to our highly regarded and critically acclaimed products. This new DAB radio is an advanced digital product capable of receiving and decoding the abundance of digital radio broadcasts available. This unit takes advantage of the very latest, third-generation DAB chipset: the highly integrated Frontier Silicon FS2020 module, which embraces the FS1010 single-chip DAB/Audio processor. The unit is based on the META processor design and Ensigma DAB IP licensed from Imagination Technologies. This is coupled to a high performance 24-bit/192kHz, WM8716 digital to analogue converter, with built-in 128fs oversampling, from respected manufacturer Wolfson Microelectronics. Our aim in realising the DAB500 was to bring into the home digital radio's beautifully clear reception, remarkable ease-of-use and superior text information. Interconnects are something that shouldn't be overlooked. Please do not compromise your system's performance by using poor quality cables. A system is only as strong as its weakest link. Your dealer can supply quality Cambridge Audio cables, either digital or analogue, that will ensure the DAB500 performs to its full potential. Please do read and retain this guide as it contains important safety and operational information. Now we invite you to sit back, relax and enjoy!

SAFETY PRECAUTIONS For your own safety please read the following instructions carefully before attempting to connect this unit to the mains. - Check that the rear of your unit indicates the correct supply voltage. - If your mains supply voltage is different, consult your dealer. This unit is designed to operate only on the supply voltage and type that is indicated on the rear panel of the unit. Connecting to other power sources may damage the unit. This equipment must be switched off when not in use and must not be used unless correctly earthed. To reduce the risk of electric shock, do not remove the units cover (or back). There are no user serviceable parts inside. Refer servicing to qualified service personnel. If the power cord is fitted with a moulded mains plug the unit must not be used if the plastic fuse carrier is not in place. Should you lose the fuse carrier the correct part must be reordered from your Cambridge Audio dealer. The lightning flash with the arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated dangerous voltage within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance instructions in the service literature relevant to this appliance. This product complies with European Low Voltage (73/23/EEC) and Electromagnetic Compatibility (89/336/EEC) Directives when used according to this instruction manual. For continued compliance only Cambridge Audio accessories should be used with this product and servicing must be referred to qualified service personnel. PLUG FITTING INSTRUCTIONS (UK ONLY) The cord supplied with this appliance is factory fitted with a 13A mains plug fitted with a 3A fuse inside. If it is necessary to change the fuse, it is important that a 3A one is used. If the plug needs to be changed because it is not suitable for your socket, or becomes damaged, it should be cut off and an appropriate plug fitted following the wiring instructions below. The plug must then be disposed of safely, as insertion into a 13A socket is likely to cause an electrical hazard. Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires should be fitted as shown in this diagram. The colours of the wires in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug. Connect them as follows:- - The wire which is coloured BLUE must be connected to the terminal which is marked with the letter N or coloured BLACK. - The wire which is coloured BROWN must be connected to the terminal which is marked with the letter L or coloured RED - The wire which is coloured GREEN/YELLOW must be connected to the terminal which is marked with the letter E or coloured GREEN. NOTE: If your model does not have an earth wire, then disregard this instruction. If a 13 Amp (BS 1363) plug is used, a 3 Amp fuse must be fitted, or if any other type of plug is used a 3 Amp or 5 Amp fuse must be fitted, either in the plug or adaptor, or on the distribution board. 3
