A short description of the patent - innovation:

		•  You don't want everybody to have access to your standard telephone unit: undesirable callers, persistant salesmen of various goods and products,marketing agencies, political parties, banks, phone maniacs.... •  But, here comes rescue to you, because only those who know additional four- digit password can reach you.

    Select Call enables its owner to accept a phone call only if after a dialled number and a received short tone signal a four-digit (protection)
password of the owner is entered. If it is a correct password, the telephone will ring and a connection will be made. In case of entering a wrong
password, Select Call informs that a call is rejected.

The Select Call is powered by means of a 220V~ /12V= adapter. If a power voltage fails or the power adapter switches off, the Select Call accepts
all calls without checking the password. By choosing one of above-mentioned options, the owner is enabled to be accessible to all callers or only
those callers who have got his password.

Installing Select Call does not prevent the telephone unit owner to make unlimited number of calls. Entering or change of password is made on the
keyboard of the owner's telephone unit, to which Select Call is connected, provided tone dialing is available. The Select Call shall be placed
between the Telephone Exchange and a standard telephone unit, and it is easy to have it installed.
