3. Handle with Care
Avoid exerting excessive force on the cabinet, the volume and selector knobs and
the push switches of AMP3800.
4. Avoid Electrostatic Discharge
Like all complex electronic devices, AMP3800 is sensitive to electrostatic discharge.
A discharge may cause malfunction or damage.
5. Installation
Use of an audio rack is recommended to maximize the sound quality and
performance of AMP3800. Installation and use of AMP3800 in the locations
described below may cause deterioration in sound quality or malfunctions.
● Locations exposed to direct sunlight, such as windowsills, and other exceptionally
warm locations, such as near heating appliances (surrounding temperature higher
than 35 ℃ ), or exceptionally cold locations (surrounding temperature lower than 5 ℃)
may prevent AMP3800 from functioning adequately.
● Damp locations exceeding 90% humidity may cause AMP3800’s metal parts to
rust, causing the unit to malfunction.
● Dusty locations may cause AMP3800 to malfunction. The accumulation of dust
outside and inside the unit may lower the performance of music signal amplification.
It may also cause contact failure of the switches and/or noise.
● Otherwise, avoid installing AMP3800 close to other transformers and electrical
motors, so as to prevent the pickup of induction hum. Also, avoid mounting
AMP3800 on surface that may be affected by vibration.
6. Avoid Lightning Strikes Damages
Disconnect the AC power cord from the AC outlet when there is a thunderstorm in
your vicinity.
7. Condensation
When AMP3800 has been brought into a warm room when the exterior temperature
is cold, or when the room temperature rises sharply from using a heater,
condensation may occur from both inside and outside the unit, hampering its
performance. If this happens, leave AMP3800 unused in the room for 1 to 2 hours
(depending on the amount of condensation), so as to bring the unit’s temperature
closer to the room temperature. The condensation should go away gradually.
8. Listening Etiquette
When adjusting the sound volume level, make sure you do not disturb other people
and your neighborhood.
