Introduction

This document is the user guide to Fast Nam Programming software. The Putsub program has been produced to perform batch programming of Nokia NHX-7 handportable telephones with the required subscriber (NAM) data and SCM data via the Mbus serial interface. The program is capable of programming TACS telephones to user defined configurations, drawing information from pre-defined data files, which can also be generated and maintained using the program. The program has a simple 'Windows' type user...

Audio

Most of audio control is performed by the NASTA 4.5 IC, which contains audio and signalling processors. Internal and headset microphones signals are connected to same input of the NASTA via bilateral switch. The EAR signal of the NASTA is fed to an external amplifier ( LM4862 ) with a dual ended type output. The XEAR signal of NASTA is carried to the transistor buffer. The internal microphone is connected to the bottom connector by means of mounting springs for automatic assembly. The...

Label printing

On successful programming of a telephone the program will automatically print two labels 1. A user guide label - containing the phone number and security lock code, General Information and NAM Programming 2. A box label - containing the ESN and a code 39 barcode representation of the phone number. The program can be configured to work with various types of label stationary using the softkey F6. The printing of numbers can also be suppressed using this configuration window. The recommended...

Program configuration files

Using function keys F2, F3 and F4 a selected configuration file ' .cfg' can be loaded, modified and stored for future use. In the 'Edit Configuration' window the cursor position can be moved up and down the list of parameters using the 'cursor up', 'cursor down', 'tab' and ' lt shift gt tab' keys. Once the desired parameter is highlighted, the value setting may be modified by using the 'cursor left' and 'cursor right' keys If pre-defined options are available, or by simply entering a new value...

PWRU Circuit

How Show Battery Temp Schematic

The main components of the Power Unit are the PSA Power Supply Asic and the CHAPS Charger Power Switch . In normal operation the baseband is powered from the phone's battery. The battery consists of three Nickel Metal Hydride cells. There is also a possibility to use batteries consisting of one Lithium-Ion cell. An external charger is used for recharging the battery and supplying power to the phone. The charger can be either a standard charger that can deliver around 400 mA or a so called...

You will then be asked to select the number on one of three allocation methods. 1. Prompt By selecting this alternative you can give numbers. The other numbers is taking from number prefix. The number prefix is described in configuration file. 2. Auto-generate In this alternative start number is 1111. The user can change numbers too. If a new phone is connected the next phone number is 1112. 3. No number In this alternative phone programming failed. The program is now ready...

DC Characteristics

The PSA regulator module in the BB unit regulates voltages VA, VRX and VTX to the fixed 2.82 V level for the RF unit. The receiver and receiver synthesizer blocks are switched on off during stand-by mode. This switching is controlled by the NASTA - audio module. If the received signal is strong enough, it switches PSA's VRX_ENA off for about half of time. This powers down all the receiver blocks and RX-VCO. Also the synthesizer module is switched to power off mode during battery save. The...

Warnings and Cautions

Please refer to the phone's user guide for instructions relating to operation, care and maintenance including important safety information. Note also the following 1. CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED WITH ELECTRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI-SKID BRAKING SYSTEMS. UNDER CERTAIN FAULT CONDITIONS, EMITTED RF ENERGY CAN AFFECT THEIR OPERATION. IF NECESSARY, CONSULT THE VEHICLE DEALER MANUFACTURER TO DETERMINE THE IMMUNITY OF VEHICLE ELECTRONIC SYSTEMS TO RF ENERGY. 2....

NHX Introduction

The NHX-7 is a radio transceiver unit designed for the ETACS network. It is a power class 4 transceiver providing 6 power levels with a maximum output power of 0.45W. Nominal battery voltage is 3.6 V and operating voltage on logic chips is 2.82 V. The transceiver consists of UIF module, system module, assembly parts and battery pack. The antenna is fixed or retractable helix. The user interface has LCD and keyboard. The accessories are same as in other Nokia DCT3 products except the active car...

Baseband Submodule

The Baseband submodule controls the internal operation of the phone. It controls the user interface, i.e. LCD driver, keyboard and audio interface functions. The module performs all signalling towards the system and carries out audio-frequency signal processing. In addition, it controls the operation of the transceiver and stores tuning data for the phone. The baseband architecture is basically similar to the previous generation. However, the system specified logical voltage level used is 2.82V...

CTRLU Circuit

The Control block CTRLU controls all functions of the phone. CTRLU controls the watchdog timer in PSA. It sends a negative pulse at approximately 0,1 s to XPWROFF pin of the PSA to keep the power on. If CTRLU fails to deliver this pulse, the PSA will remove power from the system. When power off is requested CTRLU leaves PSA watchdog without reset. After the watchdog has elapsed PSA cuts off the supply voltages from the phone. CTRLU controls also the charger on off switching in the PWRU block....
