Recording Method
Note: The Pre-Page Tone
should be disabled if the Digital
Feedback Eliminator is being
used with a zone paging system;
otherwise, the paging controller
may interpret the DTMF tone as
a request to select a zone.

Recording Method — This option specifies whether recording is to be
initiated by voice, DTMF, or contact closure. If DTMF activation is
selected, the unit will start recording a message after it detects a DTMF
tone (caused by the user pressing a key on a touch-tone phone). The
tone will not be included in the recording. If Voice activation is
selected, the unit will begin recording the moment the user starts
speaking. In both cases, recording will end approximately three
seconds after the end of the page.
You may need to adjust the DTMF Level and VOX Level controls to
ensure that DTMF tones and audio levels are measured correctly.
Recording may always be initiated by operating the Record contact
closure. It will terminate immediately after the closure is removed if
Closure activation has been selected; it will end approximately three
seconds after the page if the option switches have been set for voice or
DTMF activation.

Playback Method — This option specifies how playback is initiated.
The default setting is Auto-Play Once: the message is played back
immediately after it is recorded, or in response to a momentary closure
on the Play control. If Auto-Play Twice is selected, the message will be
repeated (played back twice).
The Play while closure active option suppresses automatic playback;
the message will be played in response to a closure on the Play
control. The message will be repeated as long as the closure is
maintained. The Play once by closure option operates similarly, but it
requires that the Play contact be opened and then closed again before
the message will be repeated.
