NME–3 PAMS Technical Documentation Installation instructions Introduction This installation guide has been prepared to provide the basic information necessary to install mobile phone. This guide is not intended to be defini- tive, because different types and models of vehicle will require different installation work.
NME–3 PAMS Technical Documentation Installation instructions Component Parts Mounting Bracket MBE–2 The mounting bracket MBE–2 shall be installed using three screws. The bracket itself can to a certain degree compensate for unevenness of the mounting surface. However, should additional spacers be required, two different types are supplied with the bracket.
NME–3 PAMS Installation instructions Technical Documentation Handsfree Microphone HFM–15 and Handsfree Speaker HFS–10 The safest and easiest way to have call while driving is use the handsfree option. The system consist of two components, the microphone HFM–15 and loudspeaker HFS–10. The microphone needs to be as close to the drivers mouth as possible and attached to a surface that is mechanically quiet.

NME–3 PAMS Technical Documentation Installation instructions The handsfree microphone can be installed on the driver’s sunvisor or the A–pillar. Ensure the microphone is as close to the driver’s mouth as pos- sible, and attached to a surface that is mechanically quiet. The micro- phone should be mounted at least 3 ft/1 m away from the handsfree unit speaker to avoid acoustic feedback.
NME–3 PAMS Installation instructions Technical Documentation Try to route the antenna cable so that possible sources of disturbances are avoided, as well anti–skid brake systems. The shorter the antenna cable, the smaller the attenuation, and the better the performance of the antenna.
NME–3 PAMS Technical Documentation Installation instructions Figure 2. Reducer Some vehicles have a main switch (e.g. gas trucks), which separates the vehicles chassis from the negative lead of the battery. Do under no cir- cumstances pass this switch, i.e. the grounding of the reducer must be taken from the body of the vehicle, NOT directly from the battery.
PAMS NME–3 Technical Documentation Installation Instructions When a relay is used, connect of series with the car radio main supply. A 100 mA fuse should be used to protect the XCRM output in event of a short circuit. Some radios have separate supplies for amplifiers and mo- tors, and another for memory backup purposes.
NME–3 PAMS Technical Documentation Installation instructions Power Antenna Control (ANTC) The orange wire of the system cable (ANTC) may be used to control dif- ferent devices on and off. The voltage in this output is +12 V whenever the phone is on. If the phone is turned off, the voltage disappears. The maxi- mum output current is 180 mA, therefore for example motorized antenna must be controlled via a relay, see picture below.
