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

• IF THE DEVICE CAN BE INSTALLED IN A VEHICLE , CARE MUST BE TAKEN ON INSTA LLATION

IN VEHICLES FITTED WITH ELECTRONIC ENGINE MANAGEMENT SYSTEMS AND ANTI–SKID BRAKING SYSTEMS. UNDER CERTAIN FAULT CONDIT IONS, 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.

• THE HANDPORTABLE TELEPHONE MUST NOT BE OPERATED IN AREAS LIKELY TO CONTAIN

POTENTIALLY EXPLOSIVE ATMOSPHERES, FOR EXAMPLE, PETROL STATIONS (SERVICE STATIONS), BLASTING AREAS ETC.

• OPERATION OF ANY RADIO TRANSMITTING EQUIPMENT, INCLUDING CELLULA R

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.

• BEFORE MAKING ANY TEST CONNECTIONS, MAKE SURE YO U HAVE SWITCHED OFF ALL

EQUIPMENT.

CAUTIONS

• Servicing and alignment must be undertaken by qualified personnel only.

• Ensure that all work is carried out at an anti–static workstation and that an anti–static wrist strap is

worn.

• Ensure that solder, wire, or foreign matter does not enter the telephone as damage may result

• Use only approved components as specified in the p arts list.

• Ensure that all components, modules, screws and insulators are correctly re–fitted after servicing and

alignment.

• Ensure that all cables and wires are correctly repositioned.

• Never test a mobile phone WCDMA transmitter with full Tx power if there is no possibility to perform the

measurements in a good performance RF-shielded room. Even low power WCDMA transmitters may disturb nearby WCDMA networks and cause problems to 3G cellular ph one commu nication in a wide area.

• During testing never activate the GSM or WCDMA transmitter without a proper antenna load, otherwise

GSM or WCDMA PA may be damaged.

To replace the covers ESD protection must be applied. All electronic parts of the product are susceptible to ESD. Resistors, too, can be

damaged by static electricity discharge. All ESD sensitive parts must be packed in metallize d protective bags during

shipping and handling outside any ESD Protected Area (EPA). Every repair action involving opening the product or handling the product

components must be done under ESD protection. ESD protected spare part packages MUST NOT be opened/closed out of an ESD

z

Do not store the phone in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics.

z

Do not store the phone in cold areas. When it warms up (to its normal temperature), moisture can form inside, which may damage electronic circuit bo ards.

z

Do not drop, knock or shake the phone. R ough handling can break internal circ uit boards.

z

Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the phone.

z

RM-685 Battery information

Battery information

Note that a new battery's full performance is achiev ed only after two or three complete charge and discharge cycles!

The battery can be charged and discharged hundreds of times but it will eventually wear out. When the operating time (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery.

Use only batteries approved by the phone manufacturer and recharge the battery only with the chargers approved by the manufacturer. Unplug the charger when not in use. Do not leave the battery connected to a charger for longer than a week, since overchargin g may shorten its lifetime. If left unused a fully charged battery will discharge itself over time.

Temperature extremes can affect the ability of your battery to charge. For good operation times with Ni-Cd/NiMh batteries, discharge the battery from time to time by leaving the

product switched on until it turns itself off (or by using the b attery d ischarge facility of any approved accessory available for the product). Do not attempt to disc harge the battery by any other means.

Use the battery only for its intended purpose. Never use any charger or battery that is damaged. Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object (coin, clip or pen)

causes direct connection of the + and – terminals of the battery (metal strips on the battery) for example when you carry a spare battery in your pocke t or purse. Short-circuiting the terminals may damage the battery or the connecting object.

Leaving the battery in hot or cold places, such as in a closed car in summer or wint er conditions, will reduce the capacity and lifetime of the battery. Always try to keep the b attery b etween 15°C and 25°C (59°F and 77°F). A phone with a hot or cold battery may temporarily not work, even when the battery is fully charged. Batteries' performance is particularly limited in tem peratures well below freezing.

Do not dispose of batteries in a fire! Dispose of batteries according to local r egulations (e.g. recycling). Do not dispose as hous ehold waste.
