8.7. The program is scanning too fast or too slow.
Scanning speed can be adjusted in the options menu for scanning. Select Tools > Options , and select the
Configure button next to the Scanning check box. This allows you to configure all aspects of your scanning
interface. The delays for scanning can be adjusted here. The scanning delays are measured in seconds.
Adjust them until you are comfortable with the rate. See sections 3.16 and 4.7 for more details on the
scanning options.
8.8. How do I speed up audio scanning?
Audio scanning can be quite slow due primarily to the time it takes to say the name of each item or group of
items being scanned (i.e. "Row 1,” "Row 2,” "Symbols Page," etc.). There are a few things that you can do to
speed up audio scanning. First, select
Tools > Options , and then select the Configure button next to the
Scanning check box. You can begin by reducing the delays. Try setting all delays to 0.1 seconds and see if
you notice a difference. To speed things up even more, select the Speech tab of the Options dialog. Now
change the speech rate for both Word and Sentence speech. Try setting them both to 400 wpm to really
speak the descriptions fast. You might have to adjust these settings repeatedly until you get the desired
combination.
8.9. My external switches are not working.
The first place to check for switch malfunctions is the connections from the switches to the switch box and
the connection from the switch box to your Palmtop device. If you have ensured that all the connections are
sound, the problem might lie in the configuration of your switch input interface.
External switches are configured through the Scanning dialog. Select Tools > Options , and then select the
Configure button next to the Scanning check box. In the Scanning dialog, make sure that the Method drop-
down menu shows the proper setting, and then select the Configure button to configure the switch(es). If
you are using an external switch, you need to select Switch 1 , Switch 2 , or Switch 3 as one of the switches
you are using. These numbers correspond to those labeled on the external switch box. Just plug your
switches into the matching switch box port. By default, the switch box is assumed to be connected to serial
communication port number 1, or
COM 1 .
8.10. I cannot get a configuration to load/save.
If you receive an error message while trying to load a configuration, it may be because the configuration file
has been corrupted on the storage card. You may want to try selecting
File > Configs > Load Configs to
recover a backup version of your configuration. Look for a configuration with the same name as the one you
are unable to load, but with a "_backup" suffix attached. If this does not work, try loading the
"Safe_<time>_backup" configuration.
If you receive an error message while trying to save a configuration ( "A problem occurred while storing
the configuration…" ), try saving the configuration once more. If you get the same message, it may be
because your storage card is out of memory. Try cleaning out unused configurations by selecting Tools >
File Utilities > Manage Files or by selecting Tools > File Utilities > Cleanup Unused Files before
attempting to save the configuration again.
