<p><b>Troubleshooting</b>\
<p>Before you call Pingtel for customer support, please print this page.  \
You can also follow these troubleshooting suggestions:\
<ul>\
<li>\
Check the size of each file stored on your phone. Click <a href=/cgi/filelist.cgi>here</a> \
to see a list; please print this list.</li>\
\
<br>If the size of any of these files is greater than 5K, a file may have \
been loaded incorrectly.\
<li>\
Verify that your device and user configuration files contain configuration \
parameters:\
</li>\
\
<ul>\
<li>\
Check your <a href=/pinger-config>pinger-config</a> file.\
</li>\
\
<li>\
Check your <a href=/user-config>user-config</a> file.\
</li>\
</ul>\
\
<li>\
If one of these files incorrectly contains some other type of data:</li>\
\
<ul>\
<li>\
Reload your pinger-config file <a href=/cgi/config.cgi>here</a>.</li>\
\
<li>\
Reload your user-config file <a href=/cgi/config.cgi>here</a>.</li>\
</ul>\
\
<li>\
If you have loaded audio files onto your phone, check the file size.</li>\
\
<ul>\
<li>\
An audio file should be no greater than 100K.</li>\
\
<li>\
If the file is larger, replace it with a smaller file <a href=/cgi/config.cgi>here</a>.\
