Your dealer is responsible for making sure that the system sounds exactly as it should and information given here is not intended to reduce this responsibility in any way. 5 8 12 15 18 20 1.0 Equipment Installation 1.1 cables and connections 2.0 Getting Started 2.1 switching on and off 2.2 running in 2.3 mains supply 2.
2.0 Getting Started 2.1 switching on and off Source components and power supplies for cd players, tuners, preamplifiers and crossovers should be switched on before switching on the amplifier(s). Always switch the amplifier(s) off and wait about a minute for its power supply capacitors to discharge before connecting or disconnecting any leads. Always use the power switch on the product rather than a mains outlet switch. 2.
3.0 Warnings Naim equipment is designed to offer the finest sound quality that can be achieved, avoiding compromise wherever possible. This can lead to circumstances that may be unfamiliar. The material that follows contains advice specifically related to Naim equipment as well as more general warnings about the use of domestic audio products. Please read it carefully.
4.0 Connection 4.1 mains lead As the colours of the wires in the mains lead of this apparatus may not correspond with the coloured markings identifying the terminals in your plug proceed as follows: The wire which is coloured GREEN-AND-YELLOW must be connected to the terminal in the plug which is marked by the letter E or by the safety earth symbol or coloured green or green-and-yellow.

n2 narcom 2 remote handset NARCOM 2 is a multi-functional remote control handset designed to be used with Naim Audio CD players, integrated amplifiers, pre-amplifiers and preset tuners. The handset control configuration is based around three types of keys: System Component Keys, Global Keys and Soft Keys. 1 System Component Keys These keys switch the operation of the “Soft Keys” into modes appropriate to each system component (preamp, CD or tuner).
3 Soft Keys These keys operate functions depending on the System Component Key setting. numeric keypad: In preamp mode the numeric keys will switch between the amplifier inputs (1 - cd, 2 - tuner, 3 - tape, 4 - av, 5 - aux 1, 6 - aux 2). In cd mode the numeric keys will select tracks. In tuner mode the numeric keys will select tuner presets or can be used directly to input station frequencies. prog: In preamp mode the prog key function varies depending upon the specific amplifier model in use.
