Utilities and industry. The Cello 4S may support one or more of the following features according to the build option(s) of the unit supplied: Single or dual pressure recording...
Considerations Environment The Cello 4S is suitable for use in non-hazardous indoor and outdoor locations, both above and below ground, in ambient temperatures in the range -20°C to +50°C (-4°F to +122°F). Cello 4S, having an ingress protection rating of IP68 (1m, or equivalent, depth for 48 hours) is suitable for use on sites likely to flood with fresh, un-contaminated, cold water.
Disposal / end of life The Cello 4S is electrical / electronic equipment and as such, at end of life, it must not be disposed of as unsorted municiple waste but collected separately in order to allow correct and environmentally sound treatment and recycling.
('RF') generated by the equipment are kept below recommended levels - for further details refer to Technolog Declaration of Conformity ('D of C') document 2099DC9000 associated with the Cello 4S, as well as the "RF exposure considerations"...
