While it is useful (almost necessary), the telephone is the
most serious threat to your privacy in existence today. Your
phone line can be wiretapped or bugged and the telephone instrument
itself can be quickly and easily converted to a very efficient
room monitor.

Not too much can be done about down-line taps. However, using
the TT07, you can check your phone line for on-premises series
and parallel bugs and wiretaps. You can also check your telephone
for the most common types of hook switch bypasses.
A hook switch bypass is a modification to the telephone instrument
so that the carbon microphone (transmitter) or dynamic earphone
(receiver) will pick up room sounds and pass them down the phone
line to a listening post even with the phone hung up. This effectively
turns the telephone into a room monitor.
The TT07 detects series devices with a resistance of 61 ohms
or more. (Most series taps have a resistance of over 100 ohms.)
It also detects parallel devices with a resistance of 65 megohms
or less. (Most parallel taps are under 30 meg-ohms.) It can
also detect certain capacitively coupled taps. It weighs 7 oz.
and is furnished in a high impact case that measures 4.25"
x 3.25" x 1.5". The unit comes complete with all necessary
plugs, cords, adapters, battery and an informative, illustrated
instruction manual.

Please note: The TT07 is not a "magic box" that is
connected permanently to a working phone line. It is a test
sets 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.
