Product Description

Simple electronic circuit lets you pick up any extension phone without the users hearing a click. Great for checking on unauthorized phone use.

CAUTION: NOT FOR ILLEGAL USE!

A notification device, such as our BEEP10 Beeper Alert System, may be required by law for the legal use of this devie -- it is your responsibility to ensure compliance with state and other applicable laws, regulations, or restrictions on the use of this device.

These are paper plans, requiring parts and assembly (also available as downloadable plans for roughly half the price).
