2 Guideline for Safety and Efficiency for the i75 VoWiFi Handsets
Read this chapter before using the i75 VoWiFi Handset.
For safe and efficient operation of the handset, observe the guidelines given in this
manual and all necessary safety precautions when using the handset. Follow the operating
instructions and adhere to all warnings and safety precautions located on the product, the
Quick Reference Guide and this User Manual.
This product shall only be used with the following batteries:
• Art.No: 660105 Battery Standard
• Art.No: 660106 Battery Extended
• Art.No: 660107 Battery Medic Standard
• Art.No: 660108 Battery Medic Extended
Desktop chargers shall only be connected with power adapters supplied by the
manufacturer.
Available power adapters are:
Art.No: FW7650 Power supply univ. AC/5V DC/1A
2.1 Precautions
•Save this manual. It includes important safety information and operating instructions.
Save all instructions for future reference.
• Connect AC (power supply) to the desktop battery charger only to designated power
sources as marked on the product.
Danger: Never alter the AC cord or plug. If the plug will not fit into the outlet, have a
proper outlet installed by a qualified electrician. Improper connection increases the risk
of electric shock.
• Position the electrical cord to the AC power supply where it is least likely to be
subjected to damage or stress.
• Remove the electrical cord from an outlet by pulling gently on the AC adapter, not by
pulling the cord.
• Remove the battery before cleaning the telephone to reduce risk of electric shock.
• Unplug the battery charger from a power source before cleaning the handset to reduce
risk of electric shock.
• Do not use auxiliary equipment with the handset which is not exclusively
recommended by the manufacturer, see 1.4 Accessories on page 2. The use of any
auxiliary equipment not recommended by the manufacturer may result in fire, electric
shock, or injury, and will void the warranty.
• Do not expose the handset to open flame.
• Do not expose the handset and the charger to direct sunlight for long periods. Keep
the handset and charger away from excessive heat and moisture.
• Protect your handset from aggressive liquids and vapours.
• Keep the handset away from strong electromagnetic fields.
• Do not allow heavy objects to fall on the handset.
• Do not allow children to play with the product packaging material. Product packaging
material is often small and may present a choking hazard.
• Do not allow children to play with the handset. It is not a toy. Children could hurt
themselves or others. Children could also damage the handset.
• Do not expose to prolong light

Battery
• Do not immerse the battery into water. This could short-circuit and damage the
battery.
• Do not expose a battery to an open flame. This could cause the battery to explode.
• Do not allow the metal contacts on the battery to touch another metal object. This
could short-circuit and damage the battery.
• Do not leave a battery where it could be subjected to extremely high temperatures,
such as inside a car on a hot day.
• Use the Desktop Charger or the wall mounted Charging Rack for charging. Charge the
battery for at least one hour the first time you use the battery. Note that the wall
mounted charger with a battery pack adapter has to be used if the battery alone is to
be charged.
• Do not attempt to take a battery apart.
• Do not disconnect the battery unless it needs to be replaced.
• Do power the handset off before removing the battery.
2.2 Environmental Requirements
Cordless Handset
• Only use the handset in temperatures between 0 oC to +40 oC (32o F to 140oF).
Battery
• Do not charge a battery when the ambient room temperature is above 40 ºC or below
5 ºC (above 104º F or below 41 ºF).
Battery disposal
Defective batteries must be returned to a collection point for chemical waste disposal.
Chemical Resistance
The alpha and numeric characters printed on the exterior of the handset have been tested
and found resistant to chipping, fading or wearing off when the handset is treated with
common cleaners and disinfectants or perspiration. The following chemicals have shown
no harmful effect:
• 3% Hydrochloric Acid
• M-alcohol (70% Methylated Ethanol)
• 60% Chlorhexidin 0.5mg/ml
Acetone can be damaging to the plastic casing of the handset and should not be used.
2.3 Frequency Range
The handset is a radio transmitter and receiver. When it is on, it receives and sends out
radio frequency (RF) energy. The handset operates on different frequency ranges
depending on market and employs commonly used modulation techniques:
EU 2412- 2472 MHz
USA/
Canada 2412- 2462 MHz

2.4 Warranty Notification
Do not disassemble the handset. Disassembling the handset voids the warranty. The
handset consists of no consumer serviceable components. Service should be performed by
Authorized Service centre only.
2.5 Potentially Explosive Atmospheres
Turn the handset off when in an area with a potentially explosive atmosphere. It is rare,
but the telephone or its accessories could generate sparks. Sparks in such areas could
cause an explosion or fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not always, clearly marked.
They include fuelling areas, (such as gas stations), below deck on boats, fuel or chemical
transfer or storage facilities, and areas where the air contains chemicals or particles (such
as grain, dust, or metal powders).
Do not transport or store flammable gas, liquid, or explosives in any compartment of a
vehicle which also contains the telephone and accessories.
In the U.S., vehicles powered by liquid petroleum gas (such as propane or butane) must
comply with the National Fire Protection Standard (NFPA-58). For a copy of this standard,
contact the National Fire Protection Association, One Battery march Park, Quince,
Massachusetts 02269, Attention: Publication Sales Division.
