– Turn the Rocket Altimeter on and see the display of hardware, software version and battery status.

– The Rocket Altimeter is always ready to ﬂy* with the automatic detection of a launch using the 9 Degrees of Freedom Internal.

– Measurement System (9DOF IMS).

– After the launch, the screen will display the data ﬁle name, altitude (m), and maximum acceleration (m/s2).

– Use the push button to access the menu.

– 2 second hold – enters or exit the menu.

– Single click – switches between menu options.

– Double click – selects an option

– When viewing a record, a double click will return you to the ﬂight history to view different ﬂight records.

– To charge the Rocket Altimeter, switch it to the “on” position and plug it in.**
