+       TeleMini is configured via the radio link. Of course, that
+       means you need to know the TeleMini radio configuration values
+       or you won't be able to communicate with it. For situations
+       when you don't have the radio configuration values, TeleMini
+       offers an 'emergency recovery' mode. In this mode, TeleMini is
+       configured as follows:
+       <itemizedlist>
+         <listitem>
+           Sets the radio frequency to 434.550MHz
+         </listitem>
+         <listitem>
+           Sets the radio calibration back to the factory value.
+         </listitem>
+         <listitem>
+           Sets the callsign to N0CALL
+         </listitem>
+         <listitem>
+           Does not go to 'pad' mode after five seconds.
+         </listitem>
+       </itemizedlist>
+      </para>
+      <para>
+       To get into 'emergency recovery' mode, first find the row of
+       four small holes opposite the switch wiring. Using a short
+       piece of small gauge wire, connect the outer two holes
+       together, then power TeleMini up. Once the red LED is lit,
+       disconnect the wire and the board should signal that it's in
+       'idle' mode after the initial five second startup period.
