 ACCESSING THE DAM REMOTELY

All remote control functions must be operated through a DTMF-tone tele-

phone. To access the remote functions, call and wait until the DAM answers,

and the OGM plays. Key-in the three digit security code (see Setting the SEC)

while the OGM is playing or the ICM recording.

To Playback an 

ICM, Remotely

After entering the correct security code, two beeps will sound and the DAM

will wait seven seconds for a command. If nothing is entered, the DAM will

disconnect. If the security code is incorrect, the DAM will continue recording

your call as an ICM.

To playback all ICMs, press “0” once and the DAM will announce “You have

<number of> message(s).” Once all ICMs have been played, the DAM will

announce “End of messages.” To repeat an ICM, press “0” again within six

seconds and all ICMs will begin to playback.

Remote Volume 

Control

To adjust volume control during remote ICM playback, press “2” to increase

volume or “1” to decrease volume.

Remote Erase of 

an ICM

To erase a current ICM, press “*” after ICM has finished playing. To erase all

ICMs, press “*” for at least one second after 

all

 ICMs have finished playing.

Remote Save of 

an ICM

Once all the ICMs have been played, hang up. The DAM will automatically

save all ICMs and continue to record new, incoming calls.

Remote Setting of 

DAM On, Off, or 

Announce only

While the OGM is playing or the ICM is recording, you can perform the follow-

ing functions:

Turn on the DAM: press “9” until three beeps sound, indicating the

machine is in answer mode. Then press “4” to confirm the setting. Four

beeps will sound for acknowledgment. 

Turn off the DAM: press “9” until two beeps sound, indicating the

machine is off. Then press “4” to confirm the setting. Four beeps will

sound for acknowledgment. 

Set DAM to Announce only: press “9” until one beep sounds, indicating

the machine will only play the OGM and cease to record ICMs. Then

press “4” to confirm the setting. Four beeps will sound for acknowl-

edgment.
