Possible cause
Overaged rechargeable
battery
Large distance between base
station and headset
Many DECT systems in the
same area
Narrowband/wideband
setting
Microphone sensitivity is not
correctly adjusted
Microphone is too far away
from your mouth
Microphone sensitivity is not
correctly adjusted
Possible solution
Replace the overaged rechargeable
battery with a new one.
Reduce the distance if possible.
Larger distances require a higher
transmission power and reduce the
talk time.
Switch off DECT systems that are
currently not required. Congestion
requires a higher transmission
power and reduces the talk time.
How many DECT systems can be
used in the same room? This
depends on various conditions:
• up to 40 D 10 systems in
narrowband mode (Americas)
• up to 80 D 10 systems in
narrowband mode
(Rest of World)
Set the base station to narrowband
transmission as it requires less
power than wideband transmission.
Adjust the microphone sensitivity.
Adjust the microphone position.
Adjust the microphone sensitivity.
