Solution
Ask a technician to replace the
X
rechargeable battery.
Reduce the distance if possible. Larger
X
distances require a higher transmission
power and reduce the talk time.
Deactivate Fast Link to save battery
X
power.
switch off DeCt systems that are
X
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:
• Americas: up to 40 sDW systems
in narrowband mode or in high
density wideband mode (available in
ePos Connect)
• Rest of World: up to 80 sDW systems
in narrowband mode or in high
density wideband mode (available in
ePos Connect)
set the base station to narrowband
X
transmission as it requires less power
than wideband transmission.
Reduce the radio range on all DeCt
X
systems in the area.
Reduce audio quality to narrowband or
X
wideband.
ensure "Fast Link" is not selected on
X
DIP switch 4.
