The “Book Drop” feature is the activation of a mic when a sound is picked up that is above the set threshold in VOX, but immediately releases because the audio source doesn’t continue for longer than 1 sec.
When the feature is “disabled”, the microphone activates when a sound is picked up and remain active for the time set within the “Release time” menu item.

Values: {-12, -11 to -3, -2, -1, 0,1,2,3 to 8}. 

The ability to Enable / Disable “Last Mic On” feature:
This feature is a desired feature when using 3rd party DSPs.
When the feature is “Enabled”, operating in VOX mode, the last (& only) microphone will ignore the “Release time” and remain permanently active until another mic becomes active. At which time, the last mic will automatically deactivate.

FUU Firmware Upgrade Utility v2.10.0.1

This release addresses the following bugs:
The new version of the FUU corrects an error during upgrade, where the baud rate in the CU is set to 38.400.

DC6990P. Voting screen may disappear preventing delegates from voting. Various scenarios exist - e.g. a voting session is started while a delegate has entered the Audio dialogue of the DC69 - e.g. the delegate hits a menu button a fraction of a second after the start of voting session.
DC6990P. The text 'Voting started on subject' is always presented in English text - no translation is possible.
Also the text 'Voting Results on Subject' hasn't been enabled for translation.
DC6990P. DC69 remains in speak when priority is set to zero - it is subsequently not possible to switch off the microphone from the unit.
DC6990P. Aborting a unit firmware upgrade in the middle of the upgrade will cause the unit to incorrectly report that firmware is valid -
condition exists until next reboot of the unit.
DC6990P. If the application is erased, but not re-written, and the unit is reset into upgrade-mode, the unit will keep resetting.

Release 6.8 (hotfix) - 2010-11-22
This hotfix addresses the following problem:
Updates the firmware in DC 6190P for correcting a timing error in the display driver.

Release 6.7.2 (hotfix) - 2010-09-29
The hotfix addresses the following problem:
In a conference with chip card login, removal of chip card on one unit can cause another DC69 unit to turn off the microphone.

Release 6.7  - 2010-05-01
This release is compatible with SW 6000 v5.3.16

Release 6.6.2 (hotfix)  - 2010-01-27
The release includes a single change - Korean font size on DC69-units is decreased to fix a bug where Korean characters were truncated.

Release 6.6
Support for user creation of labels for DC 6990P.
Support for upload of user bitmap to the DC 6990P

Release 6.5
Support for dynamic text with complex language codes (like Chinese, Thai, Russian, Arabic etc.) from the SW6000 and onto the DC6990P
Support for showing  of expanded voting weight used together with the DC 6990P

Release 6.3
Support for languages on statical DC69 labels. Labels are introduced in English, French, Italian, Spanish, Russian and Chinese.  

The DC69 units provide a setup menu for defining selectable languages - languages that the delegates must choose among during login. If only a single language is selectable, the delegates will not have to make a language selection at login.  

The CU supports storing of selectable languages into the CU configuration. The system is therefore able to preserve language settings after reset.  

Restriction: this firmware release does not yet provide support for costumization of languages and does not provide multiple language support for Delegate names, Agenda etc. when connected to SW 6000..

Fix:: This release adds improved connection in large systems - particularly.  Not all units are registered in large systems (more than 250 units).

This firmware version is compatible with software version 5.0.17 or higher. The FUU should be used when upgrading.

Release 6.2.5
This release introduces the following features:
*Support for Dual Delegate
*Support for chip cards in Dual Delegate *Support for proxy voting
*Support for removal of Speaker and Request list with SW6000
*New design of Start-up, Voting and Result screens

Release 6.1.4 (hotfix)
This hotfix address a problem identified on the DC6990P units causing the units not to retransmit votes cast under load conditions where the initial voting control message is lost. Also chip card messages are not retransmitted in case they are lost - e.g. due to collisions. The fix is a high priority fix for installations with DC6990P units where voting functionality is in use. Note that additional security on voting has been added - visual feedback on a voting unit (display on DC6990 - Led's on other) will not be updated with information before a verification has been performed by CU.

Release 6.1.3 (hotfix)
This release addresses some minor bugs in communication between CU 60xx Central Units and DC 6990P

Release 6.1.2 (hotfix)
