10.2 Display Information
The following error messages can be shown in the handset display:
Battery life is bad DTIM might not be set
correctly.
U-APSD is not used.
Cisco/Ekahau location
client settings need to
be changed.
1) Check “Beacon interval” and
“DTIM” settings in the AP.
2) Verify the coverage, since low
signal strength will make the handset
to constantly search for other APs and
thereby consuming more power.
3) Use a sniffer and check the amount
of broadcast traffic that is transmitted
on the WLAN.
4) Check if correct models of the
chargers are used.
5) Verify with another battery.
6) If the system is supposed to use U-
APSD for voice calls check the voice
power save mode parameter in the
PDM.
7) If using Cisco/Ekahau location
client, change the settings.

No access The handset is in
range, but has no
access rights.
Handset has found and
associated to the
WLAN (a wireless
network with the
configured SSID and
correct security
settings). But it cannot
connect to the
gatekeeper or the
WSG.
Switch off the handset and then switch
it on again. If this does not work,
contact the system administrator.
1) Check if the handset has an IP
address by entering the “Network info”
screen. If not check the WEP key if
used or WPA/WPA2 passphrase.
2) If using WEP, double-check the key
if the handset has no IP address. If
you have a wireless sniffer, configure
it to the correct key and try to decode
packets both from and to the handset.
3) Check the Gateway address. Try to
ping the gateway from another PC.
4) Check the WSGaddress. Try to
ping the WSG from another PC.
