+ <title>Frequency</title>
+ <para>
+ This configures which of the frequencies to use for both
+ telemetry and packet command mode. Note that if you set this
+ value via packet command mode, the TeleDongle frequency will
+ also be automatically reconfigured to match so that
+ communication will continue afterwards.

+ <section>
+ <title>RF Calibration</title>
+ <para>
+ The radios in every Altus Metrum device are calibrated at the
+ factory to ensure that they transmit and receive on the
+ specified frequency. If you need to you can adjust the calibration
+ by changing this value. Do not do this without understanding what
+ the value means, read the appendix on calibration and/or the source
+ code for more information. To change a TeleDongle's calibration,
+ you must reprogram the unit completely.

+ <title>Telemetry/RDF/APRS Enable</title>
+ <para>
+ Enables the radio for transmission during flight. When
+ disabled, the radio will not transmit anything during flight
+ at all.
+ </para>
+ </section>
+ <section>
+ <title>APRS Interval</title>
+ <para>
+ How often to transmit GPS information via APRS (in
+ seconds). When set to zero, APRS transmission is
+ disabled. This option is available on TeleMetrum v2 and
+ TeleMega boards. TeleMetrum v1 boards cannot transmit APRS
+ packets. Note that a single APRS packet takes nearly a full
+ second to transmit, so enabling this option will prevent
+ sending any other telemetry during that time.
+ </para>
+ </section>
+ <section>
+ <title>Callsign</title>
+ <para>
+ This sets the call sign included in each telemetry packet. Set this
+ as needed to conform to your local radio regulations.
+ </para>
+ </section>
+ <section>
+ <title>Maximum Log Size</title>
+ <para>
+ This sets the space (in kilobytes) allocated for each data
+ log. The available space will be divided into chunks of this
+ size. A smaller value will allow more logs to be stored,
+ a larger value will record data for longer times.
+ </para>
+ </section>
+ <section>
+ <title>Logging Trigger Motion</title>
+ <para>
+ If TeleGPS moves less than this distance over a long period
+ of time, it will not log that location, saving storage space.
+ </para>
+ </section>
+ <section>
+ <title>Position Reporting Interval</title>
+ <para>
+ This sets how often TeleGPS reports position information via
+ telemetry and to the on-board log. Reducing this value will
+ save power and logging memory consumption.
