Entries for a scan table
Scan table name
A scan table has a name that uniquely identifies it, and makes it available for selection
in other areas of the user interface of the control point.
Scanning a scan table
You can include a group of channels in a scan table, and set up some common
properties for how these channels are scanned. One of these properties is whether the
defined group of channels is scanned or not.
You can enable or disable scanning for any scan table. If enabled, the scan table is
scanned when scanning is switched on. You can also set the transceiver to scan the
channels for voice and/or data, which increases the dwell time on each channel.

Scan channels
The Scan Channels entry contains the channels that you want to group together
under the same scanning conditions. The name, frequencies and mode of each channel
that you want to scan are stored in the Scan Channels entry.
Voice detect
The Voice Detect entry sets whether or not the channels in the scan table are scanned
for voice. If you enable voice detection, the time that a transceiver dwells on a channel
defaults to 550 msec.
Channel dwell time
The channel dwell time is the length of time during scanning that the transceiver
pauses on each channel in order to detect an incoming call. This duration can be
specified (in seconds) according to the requirements of your station and the stations
with which you communicate, or you can set it to Auto. When it is set to Auto, the
transceiver calculates the channel dwell time according to the HF networks in which
the scan table is used. The maximum value of the channel dwell time, regardless of
the call system, is 10 sec.
