Basic thermal-imaging documentation, product identity and care-source notes for the HW256 series.
Checked against the identified source
Basic technical record
Values below are statements checked in the identified supplied document, not independent measurements or certifications.

Thermal/display values correspond to the supplied document and an earlier original-table audit. That lineage is not a new independent hardware test. Electrical claims remain withheld.
Not asserted as verified
Information awaiting confirmation
- Approved battery chemistry, replacement cell and charging method.
- Type-C electrical ratings and approved external supply; the later 5 V statement is not adopted.
- Independent test reports, enclosure-rating evidence, and dimension/weight measurement basis.
Non-operational information
Safety and care FAQ
May the housing be opened for routine care?
The supplied safety section says not to open the housing. Handle the unit carefully and refer visible damage or unexplained faults to qualified service personnel.
p. 7 · Safety warningsWhat should be considered after rain exposure?
The supplied safety section says to keep the unit dry and wipe the exterior dry after rain. This is not permission for immersion or high-pressure washing.
p. 7Does a Type-C connector establish charging capability?
No charging capability or electrical connection recommendation is asserted here. The source audit found inconsistent charging wording and missing electrical ratings; these remain unresolved.
Source reconciliation · unresolved electrical informationWhat does source-checked mean on this page?
The statements have been checked against the identified supplied document or explicit model-identity confirmation. This is not independent hardware testing or certification; unresolved information is listed separately.
Source noteIs the device presented as solar-viewing equipment?
No. Do not use it to observe the Sun. NASA warns of serious eye hazards when solar viewing through optics lacks purpose-designed protection.
Source noteDoes citing an IP standard certify this model?
No. IEC 60529 defines enclosure-protection classifications. A reference to the standard does not establish that a particular model has been tested or certified.
