One end of each cable is marked with a band to establish its correct orientation. Naim loudspeaker cable is correct for your system and your dealer will make up leads to suit your equipment installation. [. . . ] Use of an aerial preamplifier will disturb the muting operation of the tuner and may cause crossmodulation problems. Such preamplifiers should only be used as a last resort. In the UK, BBC and commercial radio broadcasts are usually radiated from different sites even though the target areas of the services may be similar. This means that unless the transmitters are in almost the same direction looking from your house, an aerial aligned on one transmitter will give less than optimum performance on the other. In these circumstances you should fit an aerial rotator, or a less directional aerial if appropriate. The more sensitive and directional the aerial you use, the less good will be the reception in directions other than the one towards which the aerial is pointing. If you are particularly interested in receiving a wide range of VHF transmissions an aerial rotator is a necessity. Your dealer will be familiar with local conditions and will be able to advise you on which stations are capable of being received satisfactorily. The tuner's audio output is adjustable both for level and channel balance. It is set to 400mV for the nat 01 and 340mV for the nat 02, all at 100% modulation and should match almost any preamplifier without difficulty. Preamplifier load should be more than 10K . frequency display The frequency display lights dimly until a station is received and tuned with sufficient accuracy. Horizontally polarised aerials will respond to all UK broadcasts whilst partially rejecting police and taxi transmissions, and are therefore recommended.

If you are particularly interested in receiving a wide range of VHF transmissions an aerial rotator is a necessity. Your dealer will be familiar with local conditions and will be able to advise you on which stations are capable of being received satisfactorily. The tuner's audio output is adjustable internally both for level and channel balance. It is set to 700mV and should match almost any preamplifier without difficulty. Preamplifier input impedance should be more than 10K . buttons mode: Toggles the tuner through three operational modes - frequency, scan and preset. Use of preset mode is covered overleaf in the narcom 2 remote handset section. down: In frequency mode, adjusts tuning frequency downwards in 50kHz steps or continuously if held. [. . . ] To access automatic source switching enter program mode as described above. The mon button on the amplifier will illuminate when source switching is automated. To utilise the surround sound processor unity gain function, enter program mode as described above. The mute button on the amplifier will illuminate when unity gain is selected. [. . . ]
