1.3 General Safety Information

1.3.1 Portable Operation · DO NOT hold the radio so that the antenna is very close to, or touching, exposed parts of the body, especially the face or eyes whilst transmitting. The radio will perform best if it is held in the same manner as you would hold a `land' telephone handset, with the antenna angled up and over your shoulder. · DO NOT operate the portable phone in an aircraft. Switch off your telephone. The use of a cellular telephone in an aircraft may be dangerous to the operation of the aircraft, disruption of the Cellular Network may occur, and is illegal. Failure to observe this instruction may lead to a suspension or denial of Cellular Telephone Service to the offender, or legal action, or both.

1.3.2 Mobile/Portable Operation - Telephone use in Vehicles: · All equipment must be properly grounded according to installation instructions for safe operation. · · Users are advised to turn off their equipment when at a refueling point. Safety is every driver's responsibility. Cellular telephones should only be used in situations in which the driver considers it safe to do so.

1.3.3 General · DO NOT allow children to play with any radio equipment containing a transmitter. · DO NOT operate this equipment near electrical blasting caps or in an explosive atmosphere.

L7082 / L7089
2.2 L7082 / L7089 Overview
The L7082 / L7089 is of the new TRI-BAND technology allowing global roaming using the GSM 900 / 1800 / 1900 bands(see below). The following are a few of the features that will be included with the unit. · Using the Whitecap lower voltage technology this offers good standby and talk times(see below) · Extended GSM channels · Tri-Codec allowing Full Rate / Half Rate / Enhanced Full Rate modes of transmission. · SIM Toolkit. · Built in Infrared Data link (see beow) · 3 Pin RS232 connection. · 96 x 54 row full graphics OptimaxTM with contrast control. · Internal Headset · Speaker Dependant Voice recognition (see below) · VibracallTM · VoicenotesTM · HATIS ­ Hearing aid Telephone Interconnection device. · Language support for prompts,STK, SMS and Phonebook The TRI ­ BAND technology will be implimented into the unit using bandaware technology for GSM 900 / 1800 and Knifeswitch selection should GSM 1900 selection be required. There will be 2 access choices for the user (1) throught the menu structure - Network Selection, or (2) through the quick access key. IrDA ­ Infra red Data Association, This feature will allow the user to link their mobile phone to their computer terminal. This will allow the user to upload and download information, such as phonebok information, SMS messages, FAX data etc... without the requirement for cables. The unit can also communicate with other IrDA devices such as pagers and other mobile phones. Perfect alignment of the beam is not required due to the spread of the beam. IP SMS allows SMS messages to be constucted on a PC then downloaded to the L7082 / L7089 to be transmtted. IP Phonebook allows very easy and extremely flexible download / upload of phonebook information, enabling select phonebooks available to each user, which can be quickly changed for example when travelling to different areas. The last 10 calls made and received can also be downloaded allowing databases to be created. The L7082 / L7089 can be placed into IrDA mode via either the quick access menu or through the Phone Set up menu structure ` Activated' will appear on the screen once the feature has been selected followed by `Connection Made' once transfer of data is available between the L7082 / L7089 and the other device. Speaker Dependant Voice Recognition ­ This feature allows `Voice Tags' to be allocated to upto 25 names within the users phone memory and also upto 15 Voice tags be allocated to the quick access functions. The unit must be `trained' for this function (ie the voice tags must first be read into the phones memory twice before recognition can be made.) Two main points whilst using this option. *THERE WILL BE NO SERVICE DURING `TRAINING' WHICH MEANS THE USER CANNOT RECEIVE OR MAKE CALLS DURING THIS TIME. *THE VOICE TAGS CAN ONLY BE ADDED TO THE PHONES MEMORY, AS GSM DOES NOT ALLOW THE OPTION TO STORE VOICE TAGS ONTO THE SIM CARD. Voice tags can be added to the phones memory using the usual name addition methods ie via the phonebook menu structure, using the M+ key, or using the quick access keys. To make a call to a person allocated with a voice tag, the smart button must first be pressed, then the L7082 / L7089 will ask for a name, if the name is recognised, then the name will be repeated and displayed on the screen. A call can then be placed.

of 48

For access to one of the quick access functions the quick access key must first be pressed, a name will then be asked for, if the name is recognised e.g. Battery Meter then the name will be repeated and the corresponding feature e.g. the battery meter will be displayed on the screen. If 2 names are too alike then the unit will request another name. CUG (Closed User Group) This is a network application which allows a select group of users only to use a particular group of mobile units e.g. In the circumstance where a manager of a field service team only wants the team to be able to call other users within his team (or CUG). Phase 2 USSD (Unstructured Supplementary Services Data) ­ This is an application whereby pressing a certain key or combination of keys whilst in idle mode ie not in a call can access certain network functions such as helplines etc...

5.3 Personality Transfer
5.3.1 Introduction

Personality Transfers are required when a phone is Express Exchanged or when the main board is replaced. The reason for personality transfers are to reproduce the customer's original personalized details such as menu and stored memory such as phone books etc... or even just to program a unit with basic user information such as language selection. There are two possible methods of transferring this information from unit to unit, or with a master transfer, card to unit: · Normal Transfer is used when the customer's original unit still powers up and as discussed above the customers personalized menu selections etc... are required to be transferred to the replacement unit. · Master Transfer is used when the faulty unit will not power up and the transfer is used to configure the replacement board to a set standard. Below is the procedure to set up a Master Transfer Card and to carry out each method of transfer correctly.

5.3.2 1. 2. 3.

Normal Transfer

L7082 / L7089 Under Test

NB* To test the PCB on its own without a housing or SIM card the unit must first be put into test mode and then into Tx or Rx mode using the applicable manual test commands. Ensure that a battery is present during this, as the battery acts as a SIM card presence detect for the unit. The PCB can then be taken out of the housing for any analysis.

6.7 Testing IrDA Port
To test the IrDA port the following set up should be followed, the distance between handset and IrDA port should be less than 30cm and although accurate alignment is not neccesary the two should be lined up as well as possible. Note. Software is required for both the L7082 / L7089 IrDA link and also the host IrDA port. A CD Rom will be shipped with the unit to enable data transfer, the drivers for the host IrDA device should be supplied with the device. For testing all we are looking for is the discovery frame between PC and handset.
