UM220 User Manual

When the module is in auto installation mode, the acceleration requirement is necessary. If in
fixed installation mode, this step can be omitted. For details, please refer to UM220-INS NF
user guidance manual.
Under the premise of normal driving, the forward driving speed is kept above 36 km/hour. The
longer the driving time is, the faster the calibration will be.
After the first alignment of inertial navigation (insstatus quality is 3), it is still required to drive for
about 15 minutes in the normal open environment, so as to train the inertial navigation devices
sufficiently. If the inertial navigation device enters the tunnel, garage and other complex
environments immediately after the first alignment, the navigation accuracy may be slightly poor.

Disassembly
When it is necessary to remove the module, it is recommended to melt the soldering tin of the pins
on both sides of the module with an electric soldering iron and remove the module with tweezers.
Do not use other means to remove the module (such as hot air gun blowing module), may lead to
module damage.

Package Description
The UM220-INS NF module is packaged in vacuum sealed aluminum foil anti-static bag with
desiccant and moisture-proof agent. When using reflow welding process to weld modules, please
strictly comply with IPC standard to conduct humidity control on modules. As packaging materials
such as carrier belt can only withstand the temperature of 65 degrees Celsius, modules shall be
removed from the packaging during baking. A small number of samples (usually by hand welding) are
shipped in an electrostatic bag, since manual welding does not need to consider the problem of
