WARNING
1. Do not use the DQ-4000 with the cover, or part of the cover removed or loose, as a
hazardous condition may result. Inspect the case for cracks or missing plastic. Do not
use if the DQ-4000 is damaged.
2. Use only Loadstar recommended AC Adapter, which conforms to the DQ-4000 required
voltage and current ratings.
3. Do not operate the DQ-4000 in an explosive atmosphere, or in the presence of flammable
gases or fumes.
4. Do not immerse the DQ-4000 in liquid because the housing is not fluid-tight. Humidity
specifications are specified as non-condensing only.
5. Do not substitute parts or modify the DQ-4000 to avoid the introduction of additional
hazards. Return the DQ-4000 to Loadstar for service and repair to insure all safety
features are maintained.
6. When the built-in Lithium Ion Polymer battery option is present, take care not to:
a. Operate or store in temperatures beyond -20C to 60C. Battery failure may occur.
b. Excessive barometric pressure changes may also cause the battery to fail or
outgas. The DQ-4000 is not to be used within a pressure vessel, for example.
c. Excessive physical damage, or severe product impact, may cause battery failure.
Physically damaged units should be returned to Loadstar for service and repair.
