– It's important to frequently charge
stored batteries. (Approx. every 6
months).
– Complete discharged batteries could
have the result that the batteries can
not be charged anymore.
– The typical life-time of the batteries is
5 years or 500 charging cycles.
– Encryption for the wireless system is
probably enabled and the particular
Wireless Discussion Unit has an
incorrect encryption key.
– Solution: disable encryption on the
CCU and subscribe unit again.
Or enter correct encryption key in
unit and subscribe unit again.
Hint
An LBB4115/00 Protected Trunk Splitter
can cause the problem. The maximum
power that a protected trunk splitter gives
to each tap-off is 4.5 W (refer to
Section 3.29 LBB4115/00 Tap-off unit). If
necessary, replace the LBB4115/00
Protected Trunk Splitter with an LBB4114/
00 Trunk Splitter.
Hint
The license code is not correct. Make
sure that you enter the correct license
code. When you do not have a license
code, contact your supplier.
Hint
The optical network cable that is
connected to the (digital) audio expander
is too long (refer to Section 4.2.5 Cabling).
