Ⅳ. After-sales and Others
This user manual can also be used as technical specification.
i. After-Sale
1. If there is any quality problem caused by non-human factors within
one week from the date of sale, the company is responsible for the
refund, replacement and repair; under normal use and storage
conditions, if there is any quality problem within one year dating from
the date of the product shipping out of the factory, the company will
provide free maintenance; if there is any quality problem after one
year since the date of the product shipping out of the factory, the user
can take invoice and warranty card to service department, office or
dealer, and the company provides maintenance for parts with
reasonable fees. If the user cannot provide invoices, identify accord-
ing to the company letter or the date of manufacture with the
extension of a month.
2. The following cases are not covered by the warranty: ① vulnera-
bility consumables: medication cup module, inhalation device; ②
failure caused by disassembling, repairing, or altering the product
arbitrarily; ③ failure caused by accidental dropping in use or in the
process of moving; ④ damage caused by improper use; ⑤ water,
medicine and other liquid in the main unit caused by users; ⑥ failure
caused by wrong operation not following the instructions; ⑦
damaged caused by unforeseen natural disasters (such as: floods,
earthquakes, fires, etc.).

Table 4 Recommended separation distances
Recommended separation distance between portable and mobile RF
communications equipment and the M102 Mesh Nebulizers
The Mesh Nebulizer is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customers or the
users of these YUWELL Nebulizers can help prevent electromagnetic
interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and The Mesh
Nebulizer as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in meters (m) can be estimated
using the equation applicable to the frequency of the transmitter, where
P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
Note: At 80MHz and 800MHz, the separation distance for the higher
frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects, and people.
