Configuring the conference system via the central unit

• If necessary, further reduce the number of conference units until there are no

errors reported.

Then add conference units one after

the other and observe the central unit’s

display. If an error is reported, the cause of the error might be the last added

conference unit, the cable used or metal parts that bridge the contacts of the

plug connection.

Displaying the temperature status –

“T

perature”

If the temperature within the central u

nit is too high (display: “ ”), proceed as

follows:

왘 Make sure that the air vents are not covered or blocked (see page 15).

왘 If necessary, clean the air vents (see page 104).

If the central unit is mounted into a rack:

왘 Provide additional ventilation by providing for a clearance below the central

uni

and/or installing additional fans into the rack.

When the temperature is again within the

permissible temperature range, this

is automatically detected by the central unit (display: “ ”). The temperature

check is carried out cyclically.

If, in spite of these measures, the temperature is still detected to be too high, one

of the fans might de faulty:

왘 Have the fans checked and, if necessary, replaced by qualified maintenance

rso

nnel.
