The unit weighs 9 oz. and
measures 7" x 4.6" x 2.25" (with the cover closed). It is powered by one 9 volt
alkaline battery (included). Also included are all necessary cords, plugs and
adapters along with an illustrated instruction manual.
Please note that
the TT-46 is not designed to be connected permanently to a working
phone line. It is a test set that lets you check your on-premises wiring and
telephones for eavesdropping devices or taps. In order to do this, you must be
able to disconnect your inside wiring from the telephone line coming into your
home or business.
This is done at the
interface between the telephone line and inside wiring; usually just by
unplugging a cable at the interface box mounted on the side of the building.
There is nothing difficult about this, but, of course, you must have access to
this interface box.
