Sum level
Confirming "sum level" with the soft key "ok", enables the setting of the digital audio control "SUM" (see audio functions).
Using the cursor keys this value in "dB'"steps can be changed and is effective at the audio output in stand-by mode
(no sequence running); presuming that the bypass relay is off.
A currently running sequence can change the SUM setting. Anyway, when this sequence is finished (stand-by status),
the level that was selected previously in this menu is automatically reestablished. The EXIT key switches to the prior
menu level.
Attenuation
Confirming "attenuation" with the soft key "ok, provides the possibility to set an attenuation level in the range of 0 dB
to 1OdB for the following audio signals: 'Alarms", "Gongs", and "Announcements". The setting effects all audio signals
of the corresponding group.
This menu provides the opportunity to match the DMM 4650's output level to different amplifiers and loudspeaker
systems. The EXIT key switches to the prior menu level.
init DMM 4650
Confirming "init DMM4650" with the soft key "ok', the message "DMM 4650 initsure?" and the soft keys "y=yes, n=no"
appear on the display. If this menu item is confirmed with "yes", the safety query "sure?' appears again, before a
complete initialization of the DMM 4650 to its factory default is performed. All user settings are lost!!! Important user
presets, stored in the unit, should be transferred into a PC in advance, as described in the menu "backup".
The contents of preset memory (EPROM) and message memory (Flash) are deleted or reset to their factory pre-set
defaults (see list Factory presets). The number of sound memories is detected automatically. At the end of this
procedure the number of bad flash memory blocks is indicated. Afterwards the display shows "Soft Reset" together
with soft key "ok". After pressing this soft key the initialization process is complete.
The start "init DMM 4650" is reserved for basic software updates and for applications where the unit is used differently.

display. A bank number can be selected using the cursor keys and "ok", together with the question "sure?", are
displayed in order to avoid inadvertent formatting. Formatting deletes all the audio data of the selected memory chip!!!
Important message data that is stored in the unit, should be saved in advance ("message edit play all", or "System
setup back up'). After starting the procedure with the soft key "ok", the memory chip passes different tests. Faulty
blocks are marked and upon conclusion of the tests their number is indicated on the display.
This menu item is necessary for the installation of memory extensions (NR 90205) into the DMM 4650 and updating
the internal message management. The sound memory bank 0 is firmly soldered at the circuit board (Pos. Ul 35).
Bank 1 is the retrofit pcb at position CN1 1 0, bank 2 = CN1 1 1, and bank 3 = CN1 12. After inserting the board and
