Site survey display is updated (typically every one second) with the refreshed
AP List. It can become difficult to read the details of the scanned APs, if the
update appears too frequently (especially in All mode). You have the option of
freezing the display by pressing the Freeze soft key. When enabled, the Freeze
soft key will not update the AP list until the Update is again activated. To
activate the Update, press the Update soft key.

Access Point Issues
Most, but not all, handset audio issues are associated with AP range,
positioning, and capacity. Performing a site survey as described in Run Site
Survey on page 4-55 can isolate the AP causing these types of issues. If the
handset itself is suspected, conduct a parallel site survey with a handset that is
known to be properly functioning.
DTIM is the abbreviation for Delivery Traffic Indication Message. This parameter
value indicates the time interval in terms of no beacons at which the AP releases
multicast and broadcast packets to associated clients and associated clients have
to be awaken to receive all of these multicast and broadcast packets.
