四：Precautions for use
Improper use during operation may damage the S400/S450 audio
equipment. The following methods can extend the usage time of
S400/S450.
The normal operating temperature of audio equipment is 0 º C-45 º
C. (32 º to 113 º) If exposed to excessively high ambient temperatures
for a long time, it may damage internal components and accelerate
the aging of electrical components.
The control panel of S400/S450 should not be directly exposed to
sunlight and exposed heat sources.
3. During the playback process, avoid continuously increasing the
maximum volume. An appropriate volume can prolong the playback
time and delay the use of electrical components.
