Solving coverage issues
Coverage issues are best resolved by adding and/or relocating access points.
Overlap issues may be resolved by reassigning channels to the access points or by
relocating the access points. See section 9.1 Access Point Problems for more
information.

6.2 Diagnostics Mode

The Diagnostics Mode is used to evaluate the overall quality of the link between the
handset, AP, and infrastructure side equipment, such as PBX, SVP Server, and
gateways. Unlike Site Survey, the Diagnostics Mode is used while the functional code
is running, and during a call.
When Diagnostics Mode is turned on in the Admin menu, the handset can display
diagnostic screens any time it is active (in a call).
The display of information is instigated by pressing the

key. Only four of the

diagnostic counters listed below can be shown at a time. Pressing the

key

multiple times will cycle through the various counters and the normal off hook
(PBX) display. The numeric icon at the top of the display indicates what screen

number is being displayed. For example the first time the

key is pressed, the

icon is shown, and the first four counters are displayed, the next time it is pressed,

the

icon is shown, and the next four counters are displayed, the counters will be

cycled through in this fashion until there are no more counters to be displayed. After
all the counters have been displayed, the screen returns to the normal off hook PBX
screen.
Note that the normal used of the

key is not available if Diagnostics Mode is

enabled.
The information provided by the Diagnostics Mode includes:

Screen 1

• Missed receive packet count since power up (MissedRcvCnt)

• Missed transmit packet count since power up (MissedXmtCnt)
• Receive retry count since power up (RxRetryCount)
• Transmit retry count since power up (TxRetryCount)
