8 Device set-up

8.1 General

Caution

Do not put objects on top of devices. Objects can fall through the airflow holes. A blockage of the airflow holes can cause a risk of fire.

Caution

Do not put the devices near or above a radiator, heat grill or in direct sunlight.

Caution

Do not cause vibration of the devices.

• Make sure that the area is clean.

• Make sure that the air is sufficiently cool.

• Make sure that there is sufficient lighting.

8.4 Ventilation

Keep a good airflow. Airflow holes are in the front, right and left sides of all 19-inch devices (for example, the central control unit and the audio expander).

• Put the devices on a hard and level surface.

• Put the central control unit at minimum distance of

0.10 m from walls to let sufficient air flow.

8.5 Cleaning

Caution

Do not use alcohol, ammonia or petroleum solvents or abrasive cleaners to clean the devices.

1 Disconnect the mains power supply from the

devices, if you want to clean the devices.

2 Use a soft cloth that is not fully moist with a weak

soap and water solution.

3 Let the device fully dry before you operate the

device again.

8.6 Storage

8.2 Cables

Use different cable ducts for the extension and mains cables. Identify each cable with a label and divide trunks to manageable geographic locations. In public areas where people can touch or move above the connectors and cables, use metal protection covers. Refer to the applicable protection specification of the protection covers.

8.3 Temperature

When devices are in a 19-inch rack, make sure there is rack space between the devices to let sufficient air flow. Forced airflow may be necessary to keep the temperature of the devices below the maximum temperature (refer to section 9.2). This extends the lifetime of the devices.

Note

If the central control unit is stopped or disconnected from the mains power supply for more than 100 days, the values of all system parameter are erased. This includes all the values of the parameters of the interpreter desks and the wireless access point. This does not include the subscription list.

1 Disconnect the mains power supply from the

devices, if you do not use the devices for a long time.

2 Keep the devices in a clean and dry area with a

sufficient airflow.

8.7 Acoustic feedback

Acoustic feedback (‘howling’) occurs when the sound of the loudspeakers or headphones in the system is sent to the system again by activated microphones.

table 8.1: Acoustic feedback

Source Quick solution Structural solution

The acoustic feedback is caused by the loudspeakers of the contribution devices.

Decrease the volume level of the system. For example, with the knob on the front of the central control unit (refer to section 10.6.3).

Do as follows: 1 Install a feedback suppressor

between audio input 2 and audio output 2 of the central control unit.

2 Set the audio routing mode of

the system to Insertion (refer to section 12.6).

The acoustic feedback is caused by an external public address system that is connected to the DCN Wireless digital congress network.

The acoustic feedback is caused by the headphones that are connected to the contribution devices.

Decrease the volume level of the public address system or the DCN Wireless digital congress network.

Tell the chairmen and the delegates to decrease the volume level of their headphones with their contribution devices.

Install a feedback suppressor between audio output 1 and the input of the external public address system.

Install and configure the headphones level reduction of the contribution devices. (Refer to the section about the contribution devices.)
