Headset in ATEX/IECEx classified areas
In hazardous areas, it is only permitted to use the headset adapter for Peltor headset (art. no.:
660281) in combination with an ATEX/IECEx classified Peltor headset. The headset must be
compatible with the output parameters of the headset connector as follows:
Uo= 4.2 V
Io= 169 mA
Po= 583 mW
Co= 2.2 µF
Lo= 2.2 µH
Sensitive Electronic Environment (EU/EFTA only)
Only use this product in countries where the appropriate authorities have given their
authorisation.
The CE symbol on the product certifies its conformity with the technical guidelines concerning
user safety and electro-magnetic compatibility valid at the time of approval; in accordance with
European directive No. 1999/05/EC.
The products Avaya 374x DECT Telephones comply with IP65 according to IEC 529 / EN 60
529.
Any radio-based equipment can potentially cause interference with other equipment and can be
interfered from other equipment. This also applies for DECT equipment. However due to the
very low transmission power level the changes for interference are very small. Research proves
that operational DECT telephones normally don't influence electronic equipment however some
precautions must be taken into account for sensitive electronic equipment e.g. sensitive
laboratory equipment. When DECT telephones operate in straight nearness of sensitive
electronic equipment incidental influence can appear. You are advised not to place the DECT
telephone on or close (less then 10 cm) to this kind of equipment, even in standby mode.
Regulatory Compliance Statements (EU/EFTA only)
Permission and Conformity

Frequency Range
The telephone is a radio transmitter and receiver. When it is on, it receives and sends out radio
frequency (RF) energy. The telephone operates on different frequency ranges depending on
market and employs commonly used modulation techniques:
Power Supply
The mains voltage of the adapter should match the local mains voltage, this can be 110 V or
230 V. Check if both voltages do match before installing the charger and adapter.
Safety Precautions
●Do not open the cordless telephone or charger, this could expose you to high voltages.
Have all repairs carried out by authorized service personnel.
●Avoid volume levels that may be harmful to your hearing. Exposure to excessive sound
pressure from a telephone's earpiece or headset may cause permanent hearing loss.
●Do not allow the charger and the battery contacts to come into contact with conductive
objects such as keys, paper clips, rings or bracelets.
●Do not allow the cordless telephone and charger to come into contact with water or
chemicals.
●Only use the plug-in AC adapter and battery type supplied.
●Do not use AC adapters which are visibly damaged (cracked or broken housing) and keep
the ventilation slits on the plug-in AC adapters free.
●Do not use the cordless telephones in vehicles or in hazardous locations.
●This product contains magnetic material. Be aware that small metallic objects may stick for
example to the loudspeaker. This may deteriorate the audio quality and can be harmful.
●Save this manual. It includes important safety information and operating instructions.
Save all instructions for future reference.

●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.
●Unplug the battery charger from a power source before cleaning the telephone to reduce
risk of electric shock.
●Do not use auxiliary equipment with the telephone which is not exclusively recommended
by the manufacturer, see Accessories on page 22. 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 telephone to open flame.
●Do not expose the telephone and the charger to direct sunlight for long periods. Keep the
telephone and charger away from excessive heat and moisture.
●Do not allow heavy objects to fall on the telephone.
●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 telephone. It is not a toy. Children could hurt
themselves or others. Children could also damage the telephone.
●Do not expose to prolong light.
Usage
Like all other cordless telephones, this cordless telephone uses radio signals which do not
guarantee a connection set-up under all circumstances. Generally, you should therefore not rely
exclusively on cordless telephones when making indispensable calls (for example, medical
emergencies).

Environmental Requirements
Cordless Telephone
●Use the DECT cordless telephones within the following temperature ranges:
●For 3740 telephone, from -10 °C to +55 °C (14 °F to 131 °F)
●For 3749 telephone, from -10 °C to +40 °C (14 °F to 104 °F)
●Avoid exposing the telephone to direct sunlight or close to other heat sources.
●Do not expose the telephone to open flame.
●Keep the telephone away from excessive heat and moisture.
●Avoid sudden temperature changes to prevent condensation in the telephone. It is
recommended to put the telephone into an air tight plastic bag until the temperature is
adjusted, for example, when entering or leaving a cold/heated building on a warm/cold
day.
●Protect your telephone from aggressive liquids and vapors.
●If the telephone has been exposed for water or condense, remove the battery immediately
and let it dry completely before re-inserting the battery.
●Keep the telephone away from strong electromagnetic fields.

●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 charge a battery when the ambient room temperature is above 40 ºC or below
+5 ºC (above 104 ºF or below 41 ºF).
