Voice Annunciation Option
The Voice Annunciation Option is primarily intended for use during emergency calls placed from a RED
ALERT™ Telephone. The Voice Annunciation Option allows local or remote speech programming for
location identification purposes, instructions, or any other desired messaging requirement. The message
can be programmed locally at the telephone or remotely via dial-up.
Initial Recording
N
OTE
:
The easiest method to initially program the Voice Annunciation recording is to perform the task at
a test bench. This allows control of the audio environment (background noise) and immediate adjustment
of the Voice Annunciation volume. The set up requires a test telephone line connection for the RED
ALERT™ Telephone during programming.
Message Recording
Refer to Figure 23.
1. Remove the front cover to expose the Main PCBA and the “piggy back” Voice Annunciation PCBA.
Insert two AA lithium batteries (provided with the telephone) into the battery holder of the Voice
Annunciation PCBA, observing proper polarity.
2. Connect the RED ALERT™ telephone to the telephone line and wait 35 seconds for the telephone to
initialize.
3. Locate the “record” push button on the Voice Annunciation PCBA. Position yourself approximately
12 inches from the microphone (in front of cover). To begin recording, momentarily press the record
push button. After hearing a short beep, begin speaking. The recording should be made in a
conversation-level voice. Maximum message duration is 2 minutes.
4. Upon completion of recording, momentarily press the record push button again. A short beep will
again be heard, indicating recording has ended.
5. The recording will automatically play back when the record push button is pressed the second time,
allowing verification of the message. If the message is unsatisfactory, repeat steps 3 and 4.
Volume Adjustment
The Voice Annunciation volume control is located on the Voice Annunciation PCBA and is completely
separate from the telephone audio volume control.
1. To adjust the Voice Annunciation message output volume, the Voice Annunciation PCBA must first
be placed in “playback” mode. This is accomplished by pressing and holding the record push button
until the playback message is heard over the unit’s integral speaker (typically 1 to 2 seconds).
2. Release the record push button. The recorded message will continue to play back (repeating the
message) for a maximum period of 1 minute.
3. Using the volume control potentiometer located on the Voice Annunciation PCBA, adjust the volume
as necessary.
4. Momentarily press the record push button to remove the unit from playback mode.
5. These steps can be performed any time volume control adjustment is required.
