| This is an ordinary calculator that
reveals nothing unusual even under close examination |
| yet conceals a hidden UHF transmitter
that can pick up the slightest whisper up to 40 |
| feet away and transmit with amazing
clarity to our dedicated UHF receiver.
The transmitter |
| is turned on by pushing a special key
through a hole in the side of the calculator and the |
| transmitter batteries are kept
separate to the calculator batteries, so even if the
transmitter |
| battery is exhausted, the calculator
remains fully functional to reveal nothing unusual. It is |
| powered by a 3 volt or 2 X 1.5 volt
batteries which last up to 5 day's continuously. The |
| calculator is available on channels A, B & C. |
