Announcement with a selective remote microphone DAM-2550 A:
• Select either with the keyboard of 16 keys, the 10 programmable memory keys or the memory keys of the
optional extension module DAM 2551 A any room- and group-call lines. The chosen lines and possibly
occupied lines will be indicated in the touch.
Screen LCD-display
• The integrated touch screen LCD display enables indication of system information with words and icons
and in addition, it announces groups and busy lines as well as relevant system information including the
power ( Green), fault and alarm.
• Pushing the button A (ALL) generates an all-call (all lines chosen).
• Now push the push-to-talk button (TALK) and keep it pressed, then the voice level indication will be
illuminated on the LCD.
• Now a chime signal is activated in the chosen lines to create attention.
• Start to talk after the signal slowly and clearly. Keep a 3 to 5 cm distance to the goose neck microphone
and avoid if possible all pop- and wheeze-sound, because those are reproduced too due to the high-
quality condenser microphone. Do not remove the pop-screen.
• In order to quit the announcement, release the push-to-talk button.
• Push the button C (CLEAR) in order to clear the chosen lines.
