LANSCHE AUDIO
OPERATING INSTRUCTIONS No.3
Page 14 / 14
Do not apply excessive force on the spikes when positioning the speakers, as this could cause them
to be torn off from the bottom plate
(9)
. When lifting the speakers, make sure not to injure yourself on
the spikes. When you transport your speakers, be absolutely sure to first remove the AC power cable
and any other cables connected to the No.3. Always apply the pulling force to the plug itself and
never to the cable.
13)
- When not in use
If the speakers will not be in operation for an extended period of time (for example, during a
vacation), disconnect the AC power plug. If a storm is expected, it is also advisable to disconnect
the AC power plug and speaker cable to avoid damage caused by lightning.
14)
- Service
The user should not conduct any work on the speakers apart from the operations described in these
instructions. The speakers are to be opened and repaired by qualified service personnel only.
15)
- Damage
The speaker should be immediately switched off and trained personnel should be consulted if:
a.
Power cords or plugs are damaged;
b.
Objects or liquids have found their way into the speaker;
c.
The speaker was exposed to rain.
d.
The speaker does not function properly, despite following the operating instructions. Only adjust
the operating elements as described in the instructions. Improper settings of other operating
elements can lead to damage that must then be
repaired by a qualified technician in order to
return the speaker to its normal operating condition;
e.
The device has fallen or been damaged;
f.
The device does not function properly or displays an obvious drop in performance.
16)
- Replacement parts
If replacement parts are required, make sure that service technicians use parts recommended by the
manufacturer or parts that possess the same technical characteristics as the originals. Unauthorized
replacement parts can lead to fire, electric shock, or other hazards.
17)
- Mains fuses
The electronic components of the Lansche No.3 speaker system are protected against damage in
several ways. To prevent fire, use only fuses of the type and rating specified by the manufacturer. The
technical data for the fuses in the individual voltage ranges can be found on the label located on
the bottom plate
(9)
.
18)
- Magnetic leakage fields
Each device produces a magnetic leakage field. For this reason, we recommend a minimum
distance of 0.5 m between the speakers and magnetically sensitive items (televisions, magnetic
wristwatches, computer screens, audio and video tapes, etc.).
19)
- CORONA plasma tweeters
a. The CORONA plasma tweeter emits a bright light (plasma ball) during the start up operation.
As with any bright light source avoid looking directly at it from a short distance (less than 30 cm).
b. Avoid allowing any objects to enter into the CORONA‟s plasma ball chamber (except for
cleaning purpose, see section 3.5 of this manual). This could damage the chamber.
When in operation, there is no danger of a hazardous electric shock if a metallic object should
accidentally find its way into the chamber (inserted by a child, for example).
c. During operation, the temperature at the electrode tip is about 800
°
C (1,472
°
F). Do not allow
any kind of material (especially flammable materials) to enter the chamber. Even after switching
off, the temperature remains high for at least 30 minutes.
d. During operation, the horn of the tweeter can heat up to 55
°
C (130
°
F). Depending on the
ambient temperature this can be higher.
e. CORONA plasma tweeters are highly sensitive electronic devices. Please protect them from
mechanical impacts or other mechanical influences.
