Recorder warning tone

In telecommunication, a recorder warning tone is a half-second burst[?] of 1400 Hz applied to a telephone line every 15 seconds to indicate to the called party that the calling party is recording the conversation.

Note: The recorder warning tone is required by law to be generated as an integral part of any recording device used for the purpose and is required to be not under the control of the calling party. The tone is recorded together with the conversation.
