7.1.2 Errors Displayed on the Handset
A “No Network” message indicates a Layer 1 or layer2 fault. If there is no access to t
he
WLAN, there is no AP to associate with, which may be caused by the handset being out of
range or by incorrectly configured WLAN network parameters.
The signal strength bar graph indicates that no si
gnal is being received and the handset
starts to beep once per minute. A vibrator may also be configured to indicate that no signal
is being received by accessing the parameter Device > General > No system warning. If the
parameter is set to “Sound repeatedly”, the vibrator is turned on and the handset vibrates
for up to 30 minutes.
Tip: To turn off the beep, press the mu
te button on the left side of the handset.
Examples of incorrect WLAN para
meter settings include:
• Incorrect network profile selected
• Missing or incorrect SSID
• Incorrect security parameters
• Incorrect radio settings.
