+
+		TeleGPS v1.0 has a dual greed/red LED along the edge

+		red LED goes out and the green LED turns on. If both
+		LEDs are lit, something is probably wrong with the battery.

+		TeleGPS v2.0 has the same green/red battery charging
+		status LED and adds another green LED along the same

+		antenna. This green LED indicates GPS lock status — it
+		blinks once every three seconds when the GPS receiver
+		is locked and tracking position.
