Psion Teklogix 7530 G2 Hand-Held Computer User Manual 137
Chapter 5: Configuration
Channel Tab
Channel Selection
Enabling “Manual Select” allows you to set the channel search order the 7530 G2
will use if communication quality drops and channel switching is required. If this
parameter is enabled, the 7530 G2 uses the channel switching lists specified in the
Manual Switch Table. If this parameter is disabled (unchecked), the hand-held uses
a standard algorithm to decide which channel it should switch to in the event of poor
channel quality.
Warning: It is not recommended that the “Manual Select” parameter be used
without a clear understanding of how to order the channel
sequences for optimum performance.
Manual Switch Table
• Tap on the Set Switch Table button to display the Manual Switch Table
dialog box.
This feature is used rarely. It is used when the order of channel switching needs to be
tightly controlled. The values in the “Channel” column are completed for you with
the enabled channels when this dialog box is opened. For each corresponding
enabled channel, the “List” column contains “0,0,0,0,0,0,0,0” values by default.
If communication quality falls below 46%, only the channels entered in the Manual
Switch Table are considered for channel switching. The channel search is carried out
in the order in which the channels were entered in the table.
To configure channel switching order for a particular channel:
• Highlight the channel you want to edit, and tap on the Edit Channel
List button.
