MINING TYPE
Certified Safe for Mine Surface use Under Cover Certificate T/Tel. 66.

This instrument has the same appearance as that illustrated above, but is designed and equipped for mine work, and has been approved by the Mines Department as intrinsically safe, and may, therefore, be connected with the underground circuits. In common with other certified apparatus its connection and use is governed by the Telephone and Signalling Order S.R. & O. 1938-1407. It is intended solely for use on the surface and under cover, as in offices, etc., where an ironclad telephone is out of place. It is not suitable for use below ground or in exposed positions.
