No network.
(The handset beeps
once a minute with a low
tone followed by a high
tone (during max 30
minutes). If the vibrator
is enabled, it vibrates
after the last beep.)
The handset is out of
coverage,
or faulty handset.
The handset cannot find
the wireless
infrastructure with
settings matching those
configured in the
handset.
The beeps can be stopped with
the mute button. Then go into
range.
NOTE: When re-entering the
coverage area it can take a couple
of minutes before the handset
automatically has registered into
the system.
If this does not work, contact the
system administrator.
1) Check the SSID. The SSID
configured in the handset must be
identical to the SSID configured in
the system infrastructure.
2) Check the security settings.
The security settings, that is,
authentication and encryption
must match the settings in the
system infrastructure.
3) Check for 802.11d multi
regulatory domain settings. The
handset (software version 2.x.x)
must be able to detect in which
country it is located to use the
correct channel and transmit
power settings. Later versions
have a parameter specifying if
802.11d should be used or not.
This is provided by the
infrastructure according to the
802.11d standard.
4) Check which channels are
used. The handset uses by default
channel 1, 6 and 11. If the
infrastructure is configured to use
any other channel, change it to
use only 1, 6 and 11 as this is the
recommended setting.
5) Check that the correct Network
(A, B, C or D) setting is selected.
No channel available
The handset did not
receive the expected
answer from the PBX
during call setup,
or the user attempts to
make a call when the
handset is displaying
“Messaging only”.
Make another call (when the
handset is not showing
“Messaging only”). If the handset
does not work after another try,
contact the system administrator.
