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:
Warnings:
1. CARE MUST BE TAKEN ON INSTALLATION IN VEHICLES FITTED WITH ELEC-
TRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI-SKID BRAKING SYS-
TEMS. 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. THE HANDPORTABLE TELEPHONE MUST NOT BE OPERATED IN AREAS LIKELY
TO CONTAIN POTENTIALLY EXPLOSIVE ATMOSPHERES EG PETROL STATIONS
(SERVICE STATIONS), BLASTING AREAS ETC.
3. OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLU-
LAR TELEPHONES, MAY INTERFERE WITH THE FUNCTIONALITY OF INADE-
QUATELY PROTECTED MEDICAL DEVICES. CONSULT A PHYSICIAN OR THE
MANUFACTURER OF THE MEDICAL DEVICE IF YOU HAVE ANY QUESTIONS.
OTHER ELECTRONIC EQUIPMENT MAY ALSO BE SUBJECT TO INTERFERENCE.
Cautions:
1. Servicing and alignment must be undertaken by qualified personnel only.
2. Ensure all work is carried out at an anti-static workstation and that an anti-
static wrist strap is worn.
3. Ensure solder, wire, or foreign matter does not enter the telephone as dam-
age may result.
4. Use only approved components as specified in the parts list.
5. Ensure all components, modules screws and insulators are correctly re-fit-
ted after servicing and alignment. Ensure all cables and wires are reposi-
tioned correctly.

Transceiver NSB-7
Introduction
The NSB-7 is a single band transceiver unit designed for the GSM1900 networks. It is
GSM1900 power class 1 (1W) transceiver.
The transceiver consists of System/RF module (RB9), Display module (UX7) and assembly
parts.
The transceiver has a full graphic display and the user interface is based on a jack style
UI with two soft keys.
A back mounted antenna is used, there is no connection to an external antenna.
The transceiver has a low leakage tolerant earpiece and an omnidirectional microphone,
providing excellent audio quality. The transceiver supports full rate, an enhanced full rate
and a half rate speech decoding.
An integrated IR link provides a connection between two NSB-7 transceivers or a trans-
ceiver and a PC (internal data), or a transceiver and a printer.
The small SIM (Subscriber Identity Module) card is located under the back cover of the
phone.
Operational Modes
There are five different operational modes:
• power off mode
•idlemode
• active mode
• charge mode
• local mode
In the power off mode only the circuits needed for power up are supplied.
In the idle mode circuits are powered down and only the sleep clock is running.
In the active mode all the circuits are supplied with power although some parts might be
in idle state part of the time.
The charge mode is effective in parallel with all previous modes. The charge mode itself
consists of two different states, i.e. the fast charge and the maintenance mode.
