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 10dB 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 DMM 4650" with the soft key ”ok", the message “DMM 4650 init sure?” 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 automat- ically. 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.

format Flash

Confirming “format Flash” with the soft key “ok”, the message “format Flash, bank X’” and the soft key “ok” appear on the 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. U135). Bank 1 is the retrofit pcb at position CN110, bank 2 = CN111, and bank 3 = CN112. After inserting the board and starting the“format Flash” procedure, the newly installed message memory is accessable. In case several extensions are installed, it is necessary to individually format each one them.

Flash space

Confirming “Flash space” with the soft key “ok”, the number of available flash memory chips and the free space of the sound memory in % appear in the display.

Software

Confirming “software” with the soft key “ok”, the display shoes “Dynacord DMM 4650" and the actual software revision number.

Language

Confirming “language” with the soft key “ok”, using the cursor keys provides the possibility to choose between “German” and “English”. The EXIT key switches to the prior menu level.

Backup

Confirming “Backup” with the soft key “ok” displays“Backup, excl. Msg” and the soft key “send”. The cursor keys are used to select"Exclusive message“ (= device status + gong preset + alarm preset + sequence
