A typical TeleMetrum or TeleMini installation involves attaching
only a suitable Lithium Polymer battery, a single pole switch for
power on/off, and two pairs of wires connecting e-matches for the
- apogee and main ejection charges.

By default, we use the unregulated output of the Li-Po battery directly

+ This switches between metric units (meters) and imperial
+ units (feet and miles). This affects the display of values

+ voice announcements. It does not change the units used when
+ exporting to CSV files, those are always produced in metric units.

+ <para>
+ Select this button and then select a TeleDongle Device from the list provided.
+ </para>
+ <para>
+ The first few lines of the dialog provide information about the
+ connected device, including the product name,
+ software version and hardware serial number. Below that are the
+ individual configuration entries.
+ </para>
+ <para>
+ Note that the TeleDongle itself doesn't save any configuration
+ data, the settings here are recorded on the local machine in
+ the Java preferences database. Moving the TeleDongle to
+ another machine, or using a different user account on the same
+ machine will cause settings made here to have no effect.
+ </para>
+ <para>
+ At the bottom of the dialog, there are three buttons:
+ </para>
+ <itemizedlist>
+ <listitem>
+ <para>
+ Save. This writes any changes to the
+ local Java preferences file. If you don't
+ press this button, any changes you make will be lost.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Reset. This resets the dialog to the most recently saved values,
+ erasing any changes you have made.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Close. This closes the dialog. Any unsaved changes will be
+ lost.
+ </para>
+ </listitem>

+ The rest of the dialog contains the parameters to be configured.

+ <section>
+ <title>Frequency</title>
+ <para>
+ This configures the frequency to use for both telemetry and
+ packet command mode. Set this before starting any operation
+ involving packet command mode so that it will use the right
+ frequency. Telemetry monitoring mode also provides a menu to
+ change the frequency, and that menu also sets the same Java
+ preference value used here.

+ <section>
+ <title>Radio 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. To change a TeleDongle's calibration,
+ you must reprogram the unit completely, so this entry simply
+ shows the current value and doesn't allow any changes.
