Choosing a cordless phone is easy - you just need to define some of its parameters and functions. The main such indicators are the range and safety of the phone. The first one makes it possible to maintain a stable telephone connection at a distance from the "base", and the second one ensures the protection of your telephone network from unauthorized access.
Instructions
Step 1
When purchasing a cordless telephone, give preference to a handset with a range of at least 300 m. This parameter is specified for direct signal transmission on level ground. For an apartment where communication is hampered by obstacles - furniture and walls, this distance is equivalent to 50 m. For home use, the best choice is a device with a range of 300-400 m and a radiation frequency of 30-39 MHz. A tube with a radiation frequency of 900 MHz will provide reliable signal reception at a distance of about 1.5 km.
Step 2
When using long-range handsets, the issue of security becomes relevant, protection of the radio signal from interception and "hooking", when a unique code is intercepted and a stranger, using his handset, can call your phone. Therefore, choose a DECT device, which has a complex security system and makes it impossible to register other people's radiotelephones on your base unit. Such devices with a frequency of 1880-1900 MHz have a range of up to 300-400 m, like conventional radio tubes with a frequency of 30-39 MHz, but they are somewhat more expensive.
Step 3
When buying a phone, pay attention to such parameters as battery life. If you have to conduct long negotiations on the phone, this time can be important for you. The base unit is used to recharge the batteries between calls.
Step 4
Depending on how many users the telephone will have, you can connect multiple handsets to one base unit. This is very convenient for a large family or in the office and does not allow you to install additional phones. In this case, it is convenient for the base unit to be equipped with a keypad for dialing.
Step 5
Almost all imported cordless telephones are equipped with a caller ID ETS 300659. In order for the caller to work on Russian communication lines, purchase an additional Euro-Caller ID adapter, which will allow you to correctly determine the numbers of incoming calls.
