Telephone Monitoring Kit
For extended record time on a standard cassette format, the Tele-Twin 20 Telephone Monitoring Kit "doubles over" the competition.  Dual cassette decks work together to give you a total of 20 hours record time.

10 Hours UNATTENDED Recording
Back-to-back dual cassette recorders give you 10 Full Hours of Quality, Unattended recording.  When the first recorder fills to capacity (5 Hours), the second recorder instantly leaps into action, continuing to record another 5 hours of conversation.

No Battery Drain
Best of all, there is no battery drain between telephone conversations so elapsed time between recording is no problem.  Your batteries could last for months!

Record ALL Extensions
The Tele-Twin 20 records ALL conversations from ALL extensions so none of your important calls will be missed. 

Built-in 2 Line Capacity
With the flick of a switch the Tele-Twin 20 becomes a 2 line telephone monitoring system, simultaneously recording both lines with 5 hours unattended capacity per line.  Simply plug the Tele-Twin 20  telephone connector into any 2 line jack.

Shock Proof Fitted Case
Custom, die-cut foam case protects your investment from rough handling and prying eyes.  The TT20 is designed to operate with the case open or closed.
