Telecommunication System
Introduction
New Range Rover has the option to be supplied with a built in hands free telephone system. Both variants of in car entertainment (ICE) Systems Multi-Function Display or Multi Information Display (MFD or MID) are capable of supporting telephone operation. There are two types of system which are market dependant, these are:
- NAS: based around the Motorola Time Port mobile phone
- ROW: which is based around a portable phone which utilises a standard SIM card.
The systems differ in components and frequencies used, but the operation via the vehicle controls is the same.
NAS Telephone System
The NAS telephone system is based around a Motorola Time Port mobile phone. The System comprises the following components:
- Motorola Time Port handset
- Eject box
- Control ECU
- Antenna
- Compensator
- Hands free microphone
Motorola Time Port Handset
The Motorola Time port phone is a unique Land Rover mobile telephone. It is not possible to substitute a similar Motorola mobile phone for the Time port phone.
The Time port is programed with an Electronic Serial Number (ESN) instead of use the european SIM card system.
Eject Box
The Eject box is located in the centre arm rest between the drivers and passengers seats.
Eject Box (NAS)
The Motorola Timeport phone is inserted into this eject box. The phone needs to be connected to the eject box via a cable and plug arrangement. All electrical and communication contacts are made between the phone and the eject box. Once installed the phone functions can be controlled via the MID or the MFD.
Control ECU
The telephone ECU is located in the left hand side of the luggage compartment. The telephone ECU is the AKIRA ECU. The AKIRA system offers features such as Emergency assistance (either automatically in the event of a crash or manually) and breakdown assistance. The emergency function can be automatically trigger in the event of a crash via a signal from the SRS DCU. If triggered automatically or via the instrument pack mounted button the ECU will send:
- GPS location
- VIN
- Which button pressed.
NOTE: The Mayday option can only be selected if the vehicle also has the navigation system fitted.

Multi Band Antenna
The antenna for the telephone system is located in the taildoor spoiler.
Antenna
The antenna is the same for all vehicles being a multi band type suitable for use on most networks throughout the world.
Compensator
The compensator is located in the left hand side of the luggage compartment.
The compensator is required to boost the signal from the Time port handset.
Telephone System (European)
The telephone system for the GSM markets comprises the following components:
- Eject box
- Cordless handset
- Cordless handset antenna
- Telephone ECU
- Multi band antenna
- Hands free microphone
Both systems have three 'status' LEDs fitted either on the lower right hand side of the MID or on the upper right hand side of the Multi-Function Display. They indicate the status of the telephone system as follows:
Eject Box
The eject box is located in the centre arm rest console. It holds the handset and also a SIM card reader. The SIM card reader requires the use of an adaptor to allow the use of standard small size SIM cards.
When the handset is in the Eject box the hand set battery will be charged if the ambient temperature is between 0°C and 40°C.
To release the hand set from the eject box the eject key located at the front of the box should be depressed. This raises the hand set approximately 15 out of the rest position. The eject key inscription is illuminated and this illumination is variable with the use of the instrument dimmer switch
Cardless Handset
The Cordless hand set has a graphic display on which a maximum of 4 lines each with 16 characters can be shown. In the first line, information concerning the mobile state ("Phone locked; "Connected") or the battery charge state is displayed. In the second and third lines there are various formats for inputting optional digits. In the fourth line only the softkey fields are displayed. Either as a symbol or as fixed text. On activating the menu key the second and third line of the display is available for menu selections. When menu selection is concluded the display returns to normal. All texts can be displayed in upper or lower case. This includes both the mobile handset permanent text items (e.g. menu texts) and texts edited by the user (e.g. names in phone book) The following information is displayed in the handset switched-on state, however it is not necessarily displayed during menu navigation:
- Permanent display of battery charge state
- Permanent GSM signal strength.
With the batteries fully recharged the handset can remain on stand-by for approximately 48 hours and has an air time of at approximately three hours. If the batteries are completely flat or if new batteries have been inserted full charging will take approximately six hours. To charge the batteries, place the handset in the eject box. The batteries are also charged while the car is parked (ignition off).
The handset is connected with the base station in the car by radio link. This link can be switched off for workshop purposes or where it is a market requirement. When using the handset, ensure that this switch always remains in position "1" (to the right).
Cordless Handset Antenna
The cordless handset antenna is located in the left hand side of the luggage compartment. This antenna allows the cordless handset to communicate with the Telephone ECU.
Telephone Control Unit (TCU)
The TCU located in the left hand side of the luggage compartment. The TCU sends and receives signals from the cordless handset via the handset antenna. The IOU then sends and receives signals to the GSM antenna via a co-axial cable. If the unit needs replacing, it must be configured using TestBook/T4.
Multi Band Antenna
The antenna is located in the rear tailgate spoiler and is the same component for most world markets.
