Note that for 802.11a the bands labeled DFS will vary depending on the set regulatory
domain.
In order to use a channel that is DFS protected; the handset must passively

listen for beacons from an AP on that channel and treat that AP as a DFS
Master. Before the handset can trust the AP as a reliable Master, the spectrum
management bit set in the AP's beacon must be configured to operate on DFS
channels. Consult the documentation for your AP for instructions on how to set
this parameter.
Transmit power
For subbands: The Transmit Power list opens when NavOK is pressed from the Subband
menu. A transmit power setting is required for each subband. Only one level may be set
per subband. Only those power levels which apply to the regulatory domain and 802.11
mode are listed. Navigate to the desired level and press NavOK to set and return to the
subband list. Another subband may be selected which repeats the process.
If the highlighted power transmit level is legal on all of the subbands for the set mode, an
All softkey will appear. Press the All softkey to apply that level to all subbands and return
to the subband menu where all subbands will now be selected. All overrides any previously
set power transmit levels.
Without subbands: When the 802.11 mode has no subbands, the Transmit Power list
opens when NavOK is pressed to set the mode. Only those power levels which apply to the
domain and 802.11 mode are listed. Navigate to the desired level and press NavOK. This
sets the transmit power level and exits the Regulatory Domain menus. The Network Setup
menu will again display.
 The power setting selected here specifies the maximum for that band/subband.
When Transmit Power Control (TPC) is enabled in the infrastructure, the AP
may instruct the handset to use a lower value to match its own transmit power.

Error Handling Mode
The error handling mode determines how the handset will behave when an error occurs.
The Halt on Error option will cause the handset to stop operating if an error message is
received. Unless the error is a fatal one, normal operation may be resumed by power-
cycling the handset. The Restart on Error option will cause the handset to make every effort
to reboot quietly and quickly to standby mode. In either scenario, a call in progress will be
lost.
Error detail may be shown on the display, captured by the syslog server, and may also be
available for downloading with the Handset Administration Tool.
