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 phones normally do not influence electronic equipment. However some  
precautions must be taken into account for sensitive electronic equipment, such as sensitive  
laboratory equipment. When DECT phones operate in straight nearness of sensitive electronic  
equipment, incidental influence can appear. You are advised not to place the DECT phone 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  
We, Avaya Inc., declare that the product line DECT R4 concurs with the basic requirements and  
other relevant provisions of EU Directive 1999/5/EU concerning radio equipment and

This equipment is intended for connection to radio interfaces (DECT) of Avaya PABX systems.  
It is compliant with the essential requirements of the EU-Directive 1999/5/EU (Radio and  
Telecommunication Terminal Equipment, R&TTE).  
Due to the differences of the individual public networks and network operators this compliance

FCC compliance statements  
This equipment has been tested and found to comply with the limits for a Class B digital device,  
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable  
protection against harmful interference in a residential installation. This equipment generates,  
uses and can radiate radio frequency energy and, if not installed and used in accordance with  
the instructions, may cause harmful interference to radio communications. However, there is no  
guarantee that interference will not occur in a particular installation. If this equipment does  
cause harmful interference to radio or television reception, which can be determined by turning  
the equipment off and on, the user is encouraged to try to correct the interference by one or  
more of the following measures:  
Reorient or relocate the receiving antenna.  
Increase the separation between the equipment and receiver.  
Connect the equipment into an outlet on a circuit different from that to which the receiver is  
connected.  
Consult the dealer or an experienced radio/TV technician for help.

Important Safety Information  
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:  
EU  
USA  
LA  
1880-1900 MHz  
1920-1930 MHz  
1910-1930 MHz  
1910-1920 MHz  
BR  
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.  
Remove the battery before cleaning the telephone to reduce risk of electric shock.  
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 18. 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).
