zontal and two vertical.
When the IMU is not installed in the
PADS, keep the four black protective caps
on its connectors. The caps protect the
connectors from electrostatic discharge
and dirt.
As much as possible, keep the IMU installed in the PADS and the PADS turned
on during travel. That keeps the gyro spinning and protects it from being damaged
by bumps and jolts.
“When you
remove
the caps,
put them some-

Battery Check
Travel
The backup PADS batteries
are often forgotten until they're
needed. As part of your before-
operation PMCS, check the
electrolyte level in battery cells
and clean any corrosion off
battery posts and connectors.
If your PADS doesn't get plenty of cool air,
it overheats and shuts down. That's why it's
important not to stack stuff on top of or
around the PADS. That blocks vents and the
PADS thermostat.
Make sure the IMU vents and blowers and
the power supply blowers aren't clogged with
dirt. Use an air hose to clean out the vents.
