The 6640T rrepresents tthe ccoming ttogether oof ttwo vvery ssuccessful aareas of CCambridge AAudio's pproduct llines. TThe FFM ssection oof tthe 6640T iis tthe descendant oof aa llong lline oof CCambridge AAudio ttuners ddating bback tto tthe late 11960's, wwhich rrecently iincluded ssuch aaward wwinning mmodels aas tthe T500. TThe DDigital ssection hhas aa sshorter llineage bbut nno lless ppedigree- oour two pprevious ddigital ttuners hhave bboth bbeen mmultiple aaward-wwinning units. About tthis uunit The 640T uses a combined DAB/FM module developed to offer high performance in both the digital and analogue bands. This ensures that you will be able to listen to all of your favourite radio stations irrespective of whether they have made the move to digital broadcasting. A full range of presets are available in both FM and DAB bands. The 640T also retains the input "loop through" feature that we fit to our other digital radios, that allows you to keep a high quality analogue tuner running alongside the 640T without using an additional input on your amplifier. Externally the 640T has the same high quality aluminium casework as the rest of the Azur range and is available in the same black and silver finishes. A specific version of the Azur remote is provided, giving full remote control of the tuner functions in an attractive and easy to use handset. A full set of controls are also on the front panel. The 640T can only be as good as the system it is connected to. Please do not compromise on your amplifier, speakers or cabling. We would, in particular, recommend amplification and cabling from the Cambridge Audio range with suitably revealing loudspeakers. Now we invite you to sit back, relax and enjoy!

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 unit's 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 product's 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 and installed 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 ffitting iinstructions ((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. 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. SAFETY PRECAUTIONS640T DAB/FM tuner azur DAB/FM tuner 5 Please take a moment to read these notes before installing your Azur tuner, they will enable you to get the best performance and prolong the life of the product. We advise you follow all instructions, heed all warnings and keep the instructions for future reference. This unit must be installed on a sturdy, level surface. Since the power transformers generate a magnetic hum-field of moderate strength, a turntable should not be located nearby. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. The unit must be installed in manner that makes diconnection of mains plug from the mains socket outlet (or appliance connector from the rear of the unit) possible. Do not plug your 640T directly into a power amplifier unless it has a variable output level. Do not route the power cable so that it can be walked upon or damaged by other items near it. The unit requires ventilation. Do not situate it on a rug or other soft surface and do not obstruct any air inlets or outlet grilles. Do not place in a sealed area such as a bookcase or in a cabinet. Any space open at the back (such as a dedicated equipment rack) is fine however. Do not install near any heat sources auch as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. When using for the first time it is advisable that it is left on, playing music, for at least 36 hours prior to critical listening. For subsequent use, a warm up period of 10-15 minutes is recommended for maximum enjoyment. If you do not intend to use this unit for a long period, switch it to Standby and unplug it from the mains socket. Also unplug the unit during lightning storms. WARNING - To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. This unit must not be exposed to dripping or splashing water or other liquids. No objects filled with liquid, such as vases, shall be placed on the unit. In the event of spillage, switch off immediately, disconnect from the mains supply and contact your dealer for advice. To clean the unit, wipe its case with a moist, lint-free cloth. Do not use any cleaning fluids containing alcohol, ammonia or abrasives. Do not spray an aerosol at or near your 640T. Ensure that small objects do not fall through any ventilation grille. If this happens, switch off immediately, disconnect from the mains supply and contact your dealer for advice. Refer all servicing to qualified service personnel. Servicing is required when the unit has been damaged in any way, such as a damaged power-supply cord or plug, liquid has been spilled or objects have fallen into the unit, the unit has been exposed to rain or moisture, does not operate normally, or has been dropped. If you have checked the Troubleshooting guide in the manual with no improvement, do not attempt to repair, dissassemble or reconstruct the unit. A serious electric shock could result if this precautionary measure is ignored.
