The status bar at the bottom of the screen contains three fields:

-The STATUS field shows the progress of the uploading process.

-The RS232 PORT shows the RS232 data during uploading.

-The rightmost box of the status bar shows the actual upload time.

On the supplied CD-ROM you can find a copy of the program R8brain (r8brain.exe, available as freeware at www.voxenga.com).

With the help of this program the sample rate of the .wav files can be changed, if required. It is recommended to use the lowest sample rate that does not degrade the audio quality.

Proceed as follows:

•Start the program r8brain.exe.

•Browse to the .wav file that must be modified.

•Browse to the folder in which the modified file must be placed.

•If required, change the message file name in the Browse menu.

•Enter the output sample rate in the appropriate field or click on the output sample rate in the pull-down menu (sample rates like 12 kHz are not in the list, but can be entered from the keyboard).

•Select 16-bit for Output bit depth and High or Very High for Conversion quality.

•Click on Perform r8brain. A progress bar shows the progress of the conversion.

•To convert from stereo .wav files to mono use the program Sound Recorder that comes with Windows®. Generally, you can find this program via Start > Programs > Accessories > Entertainment > Sound Recorder.

4.2 Play-back messages

When an announcement is started via a trigger contact, the corresponding trigger indicator LED (8) will light up. Single-shot triggering and repeating mode is provided. After pressing a trigger switch the announcement is played completely. If the trigger switch is still ON upon completion of the announcement, this announcement will be repeated until the trigger switch is released. Then it will complete the running announcement and stop.

Within an announcement there is no possibility for repetition loops of individual messages. However the same message may be programmed in the sequence more than once (max. 4).

Trigger inputs have serial priority, i.e. input 1 has priority over trigger input 2, 2 over 3, etc.

When an announcement is overridden with an announcement with a higher priority, the first indicator LED will extinguish and the new LED will light up. Lower priority triggers will be ignored.

The LED of the running message is flashing (2 Hz). If the current announcement is interrupted via RS232 by a higher priority call from the connected system pre-amplifier, the LED will stop flashing and light up continuously.

The front panel of the unit contains six pushbuttons (9) to activate announcements 7 to 12, effectively in parallel with the trigger inputs 7 to 12.

If the unit is connected to the LBB1925 via RS232, trigger inputs 1 through 6 will be processed with a priority equal to the high-priority setting of a connected LBB1946 call station. Trigger inputs 7 through 12 are processed with a priority equal to the low-priority setting of a connected LBB1946 call station.

This priority level affects only the priority of the announcements compared to other sources connected to the system pre-amplifier, e.g. call stations. It does not affect the priority between the trigger inputs of the message manager, which is serial.

If a repeating announcement is interrupted by a higher priority call via the system pre-amplifier LBB1925 or by a higher priority trigger input (lower contact number) and if, after the interruption, the original trigger input is still
