WARNING! Do not discard packaging until all components are confirmed working. Handle electronic components with care to avoid static damage.

Pre-Installation Planning

Plan system layout before installation.

1. Room Assessment: Determine optimal locations for microphones (ceiling center) and sensor pods (walls, away from vents).
2. Network Requirements: Ensure network has DHCP server or plan for static IP assignment. VLAN for AV devices recommended.
3. Power Requirements: Verify PoE budget on switch supports all devices (main unit: 15W, each mic: 7W, each pod: 5W).
4. Rack Space: Plan for main unit and switch in equipment rack.

CAUTION! Ensure mounting surfaces can support device weight. Use two people for ceiling installation.

Hardware Installation

• Main Unit: Install in standard 19" rack using provided brackets.
• Ceiling Microphones: Mount to T-bar ceiling grid or solid ceiling using template. Connect Ethernet to switch.
• Sensor Pods: Mount on wall at 1.5m height using screws. Connect to network via daisy-chain or direct to switch.
• Network Switch: Install in rack, connect to building network uplink.
• Cabling: Run Cat6 cables from each device to switch. Use cable ties for neatness.
• Power: Connect switch to AC power. All other devices powered via PoE.
• Audio Output: Connect main unit's audio output to room amplifier or DSP input.

Network Configuration

Devices obtain IP via DHCP by default. For static IP, use Bose Configuration Software.

Default Network Settings: Main Unit DHCP client. If no DHCP, fallback IP: 192.168.1.100.

Configuration Steps:

1. Connect laptop to main unit USB port or same network.
2. Launch Bose Configuration Software (download from Bose Pro website).
3. Discover devices. Assign static IPs if required by IT policy.
4. Set device names corresponding to room/location.
5. Configure SNMP traps or syslog for monitoring if needed.

Tip: Isolate AV traffic on separate VLAN for performance and security.

Software Setup

Use Bose Configuration Software to set up audio and sensor parameters.

1. Audio Setup: Configure microphone gain, AEC (Acoustic Echo Cancellation), noise reduction.
2. Sensor Calibration: Set thresholds for temperature (alert if >25°C), humidity, occupancy timeout.
3. Room Zones: If multiple sensor pods, define zones for granular monitoring.
4. Output Routing: Map audio output to specific channels on connected amplifier.
5. User Access: Set admin and user passwords for web interface.
6. Firmware Update: Check for and install latest firmware for all devices.
7. Save Configuration: Upload configuration to main unit and backup file.

WARNING! Do not interrupt firmware update. Ensure stable power and network.

Calibration & Testing

Calibrate system for room acoustics and verify sensor readings.

Audio Calibration: Use built-in pink noise generator and external SPL meter to set reference levels. Run automatic room adaptation for AEC.

Sensor Verification: Compare temperature/humidity readings with calibrated meter. Adjust offsets in software if needed. Test occupancy sensor by walking through room.

Operation Guidelines

Normal Operation: System continuously monitors audio and environment. Green status LED indicates normal operation.

Web Interface: Access via https://[unit-ip]. View real-time sensor data, audio meters, system health. Mute microphones globally or by zone.

Remote Control: Basic mute/unmute and LED indicator control.

CAUTION! Do not block sensor pod vents. Ensure adequate airflow around main unit in rack.

Maintenance

Regularly check system status via web interface. Clean microphone grilles with soft brush. Dust sensor pods with dry cloth.

CAUTION! Unplug power before cleaning any component. Do not use liquids or compressed air on sensors.

Regulatory & Compliance

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power to devices	PoE switch issue, cable fault	Verify switch PoE enabled; test cable; try different port; check PoE budget.
Devices not discovered in software	Network configuration, firewall	Ensure laptop on same subnet; disable firewall temporarily; check device IP via LED blink code.
No audio output	Output mapping, gain settings, cable	Verify audio output enabled in software; check gain settings; test cable and destination device.
Inaccurate sensor readings	Calibration, placement	Recalibrate sensor offset; relocate pod away from heat sources or direct sunlight.
High network latency	Network congestion, switch issues	Check switch for errors; prioritize AV traffic (QoS); ensure Cat6 cable used.
Web interface inaccessible	IP address change, credentials	Rediscover device IP; reset to factory defaults via pinhole if credentials lost.

Factory Reset: Press and hold pinhole reset button on main unit for 10 seconds. All settings will be lost.

Service: Contact Bose Professional Support or authorized service center. Do not open units; no user-serviceable parts inside.
