General Safety
Warning
Exposure to excessive sound pressure levels can lead to impaired hearing and cause damage to the ear.
Please read and observe ALL of the following notes:
·
Check all of the hardware devices for transport damage.
·
Any devices showing signs of mechanical damage or damage from the spillage of liquids MUST NOT
be connected to the mains supply or disconnected from the mains immediately by pulling out the
power lead.
·
All devices MUST be grounded. Grounding connectors are provided on all devices. In addition, all
low-voltage devices external to the system must also be grounded before operation.
·
For Scandinavian countries, ALWAYS use a grounded mains connection, to prevent the device from
being grounded through Ethernet or other signal connections.
·
Do NOT use the system at extreme temperatures - observe the temperature range and humidity
specified in the installation instructions.
·
Do NOT expose devices to liquids which may drip or splash.
·
Do NOT place objects filled with liquids, such as vases, upon a device.
·
Only service staff may replace batteries.
·
CAUTION: Danger of explosion if battery is incorrectly replaced - Replace only with the same or
equivalent type.
Servicing of components inside a device MUST only be carried out by qualified service personnel according
to the following guidelines:
·
Before removing parts of the casing, shields, etc. the device MUST be switched off and disconnected
from all mains.
·
Before opening a device, the power supply capacitor MUST be discharged with a suitable resistor.
·
Components that carry heavy electrical loads, such as power transistors and resistors, should NOT
be touched until cool to avoid burns.
Servicing unprotected powered devices may only be carried out by qualified service personnel at their own
risk. The following instructions MUST be observed:
·
NEVER touch bare wires or circuitry.
·
Use insulated tools ONLY.
·
DO NOT touch metal semi-conductor casings as they can bear high voltages.
