Sec. 314.

At the time that a 9-1-1 system becomes operational or as soon as feasible thereafter, each service supplier or other owner or lessee of a pay station telephone to be operated within the 9-1-1 service district shall do both of the following:

Convert or cause to be converted each such telephone to permit a caller to dial 9-1-1 without first inserting a coin or paying any other charge.

Prominently display on each such telephone a notice advising callers to dial 9-1-1 in an emergency and that deposit of a coin is not required.

After commencement of 9-1-1 service in a 9-1-1 service district, a person shall not install, cause to be installed, or offer for use within the 9-1-1 district a pay station telephone, whether on public or private premises, unless the telephone is capable of accepting a 9-1-1 call without prior insertion of a coin or payment of any other charge, and displays the notice described in subsection (1).

All costs of a service supplier associated with converting pay station telephones and maintaining the required notices under this section shall be borne by the service users within the 9-1-1 district.
