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 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. 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 CELLULAR TELEPHONES, MAY INTERFERE WITH
THE FUNCTIONALITY OF INADEQUATELY 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 damage may result.
4. Use only approved components as specified in the parts list.
5. Ensure all components, modules screws and insulators are
correctly re–fitted after servicing and alignment. Ensure all cables
and wires are repositioned correctly.

System Connector
This section describes the electrical connection and interface levels
between the baseband, RF and UI parts. The electrical interface
specifications are collected into tables that cover a connector or a defined
interface.
The system connector includes the following parts:
– DC connector for external plug–in charger and a desktop charger
– System connector for accessories and intelligent battery packs
The System connector is used to connect the transceiver to accessories.
System connector pins can also be used to connect intelligent battery
packs to the transceiver.
