2G / 3G

Refers to 2nd generation and 3rd generation mobile phone networks. 3G was developed to provide faster speed and greater capacity for data communication over mobile networks in addition to voice communication.



A technology that enables digital devices (see IP) to communicate over traditional, fixed-line networks (see PSTN).

Amplified sound

In telecom products, handset and speaker volume can be amplified to help compensate for hearing loss. With Doro products, the level of amplification is sometimes specified, e.g. ‘Handset volume amplified by up to 30dB.’ In this example, the receiver volume can be raised to a level that is as much as 30dB higher than normal receiver volume.


BIO 21

The Biennial of Industrial Design (BIO) is an international design exhibition in Slovenia that takes place every other year. Its purpose is to showcase contemporary trends in international design by selecting well-designed products with an emphasis on quality, originality and innovation.

Bluetooth is a radio technology commonly used to connect different electronic devices when brought within 10m of each other, e.g. a mobile phone and a wireless headset or neckloop. One of the biggest advantages of Bluetooth is ‘wireless freedom,’ i.e. connectivity without the hassle of cables.

The name is derived from Harald Blåtand (Bluetooth), the 10th century Danish King known for helping to unite warring factions in parts of what is now Norway, Sweden and Denmark. Today Bluetooth helps to unite different types of electronic products made by different manufacturers.

Digital Enhanced Cordless Telecommunications (DECT) is a European standard for digital cordless phone systems. In comparison with other standards, DECT offers benefits such as longer range, internal calls between handsets (intercom functionality) and, most of all, interference-free operation for clearer sound. The standard also enables handsets and base stations made by different manufacturers to function together through the Generic Access Profile (GAP).

Doro Secure IP Protocol

A protocol is a set of rules that electronic devices use in order to be able to communicate with each other. The Doro Secure IP Protocol is used for transmitting data such as alerts, remote settings etc. over mobile communication networks. It has been specially developed to provide secure communication between a telecare gateway and the telecare provider.

Doro Secure RF Protocol

A protocol is a set of rules that electronic devices use in order to be able to communicate with each other. The Doro Secure RF Protocol is used for the communication between a telecare gateway and the devices that trigger them, such as alarm buttons and pendants. Other triggers could be environmental sensors for detecting smoke, water leakages, extreme temperatures, etc. The protocol has been specially developed to provide reliable, operation by using a special radio frequency sometimes referred to as the ‘European social alarm frequency.’


Eco functionality

An initiative by Doro to guide environmentally aware consumers who wish to make a ‘greener’ choice. The green eco functionality label is used with Doro’s cordless DECT phones developed to use less power during both operation and standby, and to automatically reduce transmission power when the handset and base unit are closer together. All Doro products carrying the eco functionality label are also ENERGY STAR approved.

Emergency SMS and call button

A special security feature found on most Doro mobile phones. When pressed and held for a number of seconds, the phone automatically sends a pre-recorded SMS text message to a list of contacts and begins dialling each number in a call list until someone answers.

European social alarm frequency

This is an unofficial term for the specific radio frequency (869 MHz) used for telecare and social alarm devices in compliance with European standards EN 300.220. This is to ensure that makers of other types of radio equipment, e.g. walkie talkies, do not use this frequency, which might cause interference that could reduce reliability of the telecare equipment.


Fixed wireless

This refers to devices that communicate using radio communication instead of through a cable connection, but are intended for use in a fixed location such as a home. In contrast to mobile wireless devices such as a mobile phone, a fixed wireless device must usually be connected to the power mains using a power cord, whereas mobile wireless devices are generally battery powered.


GAP compatible

A term relating to DECT cordless phones that incorporate the Generic Access Profile (GAP). This guarantees basic interoperability with any other GAP compatible product manufactured by any other manufacturer.

See also DECT


A device that enables communication between networks that use different communications protocols , allowing information to be passed from one to another.


The most widely used standard for mobile telephony around the world. GSM is an abbreviation for Global System for Mobile Communications (originally for Groupe Speciale Mobile) and dates back to the mid 1980’s.

HAC rating (for U.S.)

Doro phones carrying the HAC symbol sometimes display a HAC rating. This is because digital wireless phones must be rated for Hearing Aid Compatibility (HAC) if they are to be used in the U.S.

Rating is done according to two sets of standards: an ‘M’ rating for acoustic coupling with hearing aids that do not operate in telecoil mode, and a ‘T’ rating for magnetic coupling with hearing aids operating in telecoil mode. A phone is considered hearing aid compatible for acoustic coupling if it has an ‘M3’ or ‘M4’ rating, and for magnetic coupling if it has a ‘T3’ or ‘T4’ rating. M4/T4 is the best possible HAC rating.

According to the U.S. standard, even the hearing aid’s immunity to interference can be rated from M1 to M4. Adding this rating to the phone’s rating gives a better indication of how well the two will work together. For example, an hearing aid rated M2 used together with a phone rated M3 has a sum of 5. A sum of six or higher indicates that the phone would provide excellent performance with that particular hearing aid.

Hearing Aid Compatibility

Digital wireless phones (mobile phones and DECT cordless phones) sometimes cause interference with hearing aids such as feedback or buzzing noises due to electromagnetic energy from the phone’s antenna, backlight, or other components. To improve usability with digital wireless phones, some hearing aids are equipped with a telecoil.

Because of the risk for interference, digital wireless phones designed for use with hearing aids are required to meet international Hearing Aid Compatibility (HAC) standards. Doro phones carrying the HAC symbol meet all such standards. Note that the HAC symbol is sometimes shown with a number indicating the device’s HAC rating, a requirement for digital wireless phones sold in the U.S. as ‘hearing aid compatible.'

IP rating

IP is an abbreviation for “Ingress Protection”. An IP rating indicates that the enclosure of a device has been tested to see how well it prevents objects and liquids from getting inside. The rating consists of “IP” followed by two digits, e.g. “IP 56”. The higher the rating the better the device is protected. The first digit refers to solid objects such as dirt, dust, etc. It should be no lower than 6 to ensure that dust will not affect the device’s function. The second digit refers to water. It should be no lower than 5 to ensure that water from water jets (e.g. when showering) will not have any harmful affects. A value of 7 indicates that the device is unaffected even after being in 1 m of water for 30 minutes.
