Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning. 6 Attachments - Do not use attachments not recommended by the product manufacturer as they may cause hazards. 7 Water and Moisture - Do not use this unit near water, for example near a bathtub, washbowl, kitchen sink, or laundry basket, in a wet basement, near a swimming pool, in an unprotected outdoor installation or any area which is classified as a wet location. 8 Accessories - Do not place this unit on an unstable stand, tripod, bracket or mount. This unit may fall, causing serious injury to a person and serious damage to the unit. Use only a stand, tripod, bracket or mount recommended by the manufacturer, or sold with the product. Any mounting of the unit should follow the manufacturer's instructions, and should use a mounting accessory recommended by the manufacturer. An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to overturn. 9 Ventilation - Openings in the enclosure, if any, are provided for ventilation and to ensure reliable operation of the unit and to protect it from overheating. These openings must not be blocked or covered. The unit should not be placed in a built-in installation unless proper ventilation is provided or the manufacturer's instructions have been adhered to. 10 Power sources - Units should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply you plan to use, consult your appliance dealer or local power company. For units intended to operate from battery power, or other sources, refer to the "Installation and User Instructions". 11 Grounding or polarisation - This unit may be equipped with a polarised alternating current line plug (a plug having one blade wider than the other). This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the plug. If the plug still fails to fit, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the polarised plug. Alternatively, this unit may be equipped with a 3-wire grounding type plug having a third (grounding) pin. This plug will only fit into a grounding-type power outlet. This is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type lug.

This requires a microphone with a priority switch on contacts 4 and 5 of the 5-pin DIN-connector, such as the table-top microphone LBB 1950. In this mode, microphone 1 will have priority over microphones 2 and 3 and the background music. Activating this microphone will mute the other microphones and the music and will also override zone switching and zone attenuation. Priority announcements will even be heard in deselected zones. This mode is normally used for important (emergency) announcements. You can select a chime signal to precede such a priority call with configuration switch 3, a speech filter with configuration switch 4 and phantom power with configuration switch 5. VOX mode: Connect the microphone to the phone jack socket at the front of the unit and enable the VOX mode with configuration switch 2 (set to ON-position). This mode will attenuate the background music or microphones 2 and 3 to a preset ducking level as long as you speak into the microphone. It is normally used with handheld microphones like the LBC 2900/15 for making casual announcements, temporarily surpressing the music. Background music and announcements will be heard in the selected zones. The front connection for microphone 1 does not have phantom power for electret or condenser microphones, so a dynamic microphone must be used. A chime is not available in this mode, but you can select the speech filter via configuration switch 4. When no priority or VOX mode has been selected, microphone 1 will just mix with the background music or the other microphones to the selected zones.

This Plena System Amplifier has a very flexible output configuration, allowing for different groups of loudspeakers. • Connect 100 V-loudspeakers for zone 1 to the 100 V-/0-terminals of zone 1. The selection button and the output attenuator for zone 1 (both on the front panel) control this output. If a low impedance loudspeaker is used for zone 1, connect it to the 8 Ohm- / 0-terminals of zone 1, but now the output level will not be affected by the attenuator. • Proceed in the same way for zone 2. • Connect 100 V-loudspeakers that should receive only priority announcements from microphone 1 to the Call Only 100 V- /0-terminals. For this, the priority mode must be enabled (see §4.2). The Call Active terminals provide voltage free relay contacts. This contact is closed as long as a priority call is active. This contact may be used for overriding remote volume controls or other purposes. It is switched together with the Call Only loudspeaker zone. Note Ensure that the loudspeakers are wired in phase by connecting the 0-terminals of loudspeakers in the same zone together to the amplifier 0-terminal. Caution Connect 100 V-loudspeakers in the same zone just in parallel, but take care that the total power of the loudspeakers, i.e. the load, does not exceed the 120 W power rating of this Plena unit Caution It is not recommended to use both low impedance loudspeakers and 100 V-loudspeakers simultaneously. Multiple low impedance loudspeakers should be connected in series or parallel so that the total impedance is more than 8 Ohm.

Use the music source selection button (26) to select the built-in CD-player/tuner or an auxiliary source. If the auxiliary source is selected, the CD-player and the tuner are switched off. If the CD-player/tuner is selected, the CD-player will be active as long as it is playing. If the CD-player stops, the tuner will take over automatically. 5.1.2 Volume and tone control • • Use the master volume control (22) to control the volume of the music/microphone mix. The bass and treble tone controls (23 and 24) affect the microphones as well as the music. 5.1.3 Zone selection • • Use the output attenuators (20 and 18) to balance the sound level in zones 1 and 2, respectively. Use the zone selection buttons (21 and 19) to switch a zone on or off. The priority microphone active LED (17) indicates that a priority call is active. Such a priority call overrides the zone selection and attenuation settings. A priority call addresses all zones with 0 dB attenuation. 5.2 Operation of tuner 5.2.1 Station selection • • Use the tuner FM/AM selection key (13) to choose between FM and AM reception. Use the tuner frequency up/down keys (12) to step up or down in frequency. Prolonged pressing makes the tuner search for the next station.

Press the tuner memory keys M1/6 to M5/10 (10) for memory position 1 to 5. Or • • Press the tuner program key (15), the tuner shift key (16) and the tuner memory keys M1/6 to M5/10 (10) for memory position 6 to 10. The tuner display (11) shows 'MEMORY' during this process. Both for AM and FM, 10 presets are available. Saved presets are selected by pressing the tuner memory keys M1/6 to M5/10 (10) or by pressing the tuner shift key (16) followed by M1/6 to M5/10. For easy selection, pressing the tuner scan key (14) monitors the presets by selecting all 10 presets sequentially for 5 seconds. 5.3 Operation of CD-player 5.3.1 Track selection Note After inserting a new CD, the CD-player detects the type of CD and shows it on the CD display (7): 'CD' for an audio-CD or 'MP3' for a disc containing MP3-files. Note that loading of MP3-CD's may take longer, depending on the number of tracks and subdirectories, as an internal table of contents is made. The MP3-files in the root directory and in the subdirectories are all put in separate folders for easy track selection. The folder number is indicated on the display, followed by the track number and the time. For track selection on audio-CD's proceed as follows: • Shortly press the CD previous key (5) and/or the CD next key (8) to select the track. Prolonged pressing results in fast reverse or fast forward. • Use the CD pause/play key (6) to pause or to play (resume playing). • Use the CD stop/eject key (9) to stop playing (press once) and/or to eject the CD (press twice). For track selection on MP3-CD's first select the folder that contains the track. Proceed as follows: • Press the CD MP3 folder selection key (2). • Press the CD previous key (5) and/or the CD next key (8). The display shows 'FOLDER' during this process. Pressing the CD MP3 folder selection key once more resumes the track selection mode in the selected folder. U Bosch Security Systems | 2003-09 | 3922 988 25012en U U By repeatedly pressing the CD repeat key (4) you select the following modes: - Playing all tracks (MP3: in all folders) and stop. - Repeating the current track. The display shows '1'. - Repeating all MP3-tracks within the current folder. The display shows ' '. - Repeating all tracks (MP3: in all folders). The display shows ' '. - Random playing of tracks (MP3: in all folders). The display shows 'RANDOM'. Plena BGM/Paging System | Installation and Operating Manual |Operation en | 19 If a MP3-CD is stopped and loaded again, the player will resume playing where it was stopped. In this way it is avoided that only the first part of a very long MP3-CD is played over and over again each day. If, however, an audio-CD is stopped and loaded again, it just starts with track 1. 5.3.2Programming To program a playlist selection: • Press the CD program key (3). • Select a track by pressing the CD previous key (5) and/or the CD next key (8). In the case of a MP3-CD folder selection is possible, as described above. • Press the CD repeat key (4) to store the first track and step to the next track of the playlist, open for selection. • Repeat this process until the playlist is finished. • Finally press the CD pause/play key (6) to start playback of the playlist. 5.4 Creation of MP3 CD-R's You can make your own MP3 CD-R's (CD-ROM's) on a normal PC with a CD-burner. Numerous programs for this purpose are available as freeware or shareware. Some websites to download from are: www.mp3.com, www.download.com, www.shareware.com and www.zdnet.com. Search there, or in a general search program as www.google.com, for 'CD-ripper'. You can collect your MP3-files in different subdirectories or folders on your PC and transfer these files to the CD-R. Always use the file name extension .mp3. Constant MP3-bit rates (CBR) of 32 - 320 kbps are supported, as well as variable bit rate (VBR) files. Note As the reflectivity of a CD-RW (CD-Rewritable) is far below that of a CD and a CD-R, playback of CD-RW's is not guaranteed. On the CD-R the ISO-9660 file system should be used. Do not use the UDF file system.
