+== Handling Precautions
+
+	All Altus Metrum products are sophisticated electronic devices.
+	When handled gently and properly installed in an air-frame, they
+	will deliver impressive results.  However, as with all electronic
+	devices, there are some precautions you must take.
+
+	[WARNING]
+	The Lithium Polymer rechargeable batteries have an
+	extraordinary power density.  This is great because we can fly with
+	much less battery mass than if we used alkaline batteries or previous
+	generation rechargeable batteries... but if they are punctured
+	or their leads are allowed to short, they can and will release their
+	energy very rapidly!
+	Thus we recommend that you take some care when handling our batteries
+	and consider giving them some extra protection in your air-frame.  We
+	often wrap them in suitable scraps of closed-cell packing foam before
+	strapping them down, for example.
+
+	The barometric sensors used on all of our flight computers are
+	sensitive to sunlight.  In normal mounting situations, the baro sensor
+	and all of the other surface mount components
+	are “down” towards whatever the underlying mounting surface is, so
+	this is not normally a problem.  Please consider this when designing an
+	installation in an air-frame with a see-through plastic payload bay.  It
+	is particularly important to
+	consider this with TeleMini v1.0, both because the baro sensor is on the
+	“top” of the board, and because many model rockets with payload bays
+	use clear plastic for the payload bay!  Replacing these with an opaque
+	cardboard tube, painting them, or wrapping them with a layer of masking
+	tape are all reasonable approaches to keep the sensor out of direct
+	sunlight.
+
+	The barometric sensor sampling port must be able to “breathe”,
+	both by not being covered by foam or tape or other materials that might
+	directly block the hole on the top of the sensor, and also by having a
+	suitable static vent to outside air.
+
+	As with all other rocketry electronics, Altus Metrum altimeters must
+	be protected from exposure to corrosive motor exhaust and ejection
+	charge gasses.
