WARNING
To keep the EXPC-1319 within the IP66 rating’s waterproof specifications, when the
USB ports are not in use operators must replace the protective caps and the tethers,
and make sure they have been properly fastened. Please note that when reinstalling
the protective caps they must be tightened to 136 N-cm (12 in-lbs) to ensure the
unit is sealed to IP66 specifications.
In addition, because of the danger posed by the maximum 5V @ 500 mA power
supply of standard USB ports, care must be taken to protect the EXPC-1319 from
power accidents in damp environments. To guarantee safety from severe electrical
shoks or electrocution, in damp conditions users should disconnect the entire
computer from its power source before connecting or disconnecting any USB
devices.
