NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid
direct sunlight, heavy dirt, and strong vibrations. Only operate the device within the ambient conditions specied in the chapter
‘Technical specications’ of this user manual. Avoid heavy temperature uctuations and do not switch the device on immediately
after it was exposed to temperature uctuations (for example after transport at low outside temperatures). Dust and dirt inside can
damage the unit. When operated in harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by
qualied service personnel at regular intervals to prevent overheating and other malfunction.
NOTICE!
External power supply
The device is powered by an external power supply. Before connecting the external power supply, ensure that the input voltage (AC
outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual current circuit breaker. Failure to do
so could result in damage to the device and possibly the user. Unplug the external power supply before electrical storms occur and
when the device is unused for long periods of time to reduce the risk of electric shock or re.
NOTICE!
Radio interference
This device emits electromagnetic signals. This can cause interference due to overlapping radio waves. Do not use the device in
locations where the use of wireless devices is prohibited.

4.2 Receiver
The unit has been designed for rack mounting in a standard 19" rack; it occupies one rack unit
(RU). The xing material required for assembly is included.
NOTICE!
External power supply
The device is powered by an external power supply. Before connecting the
external power supply, ensure that the input voltage (AC outlet) matches the
voltage rating of the device and that the AC outlet is protected by a residual cur‐
rent circuit breaker. Failure to do so could result in damage to the device and pos‐
sibly the user.
Unplug the external power supply before electrical storms occur and when the
device is unused for long periods of time to reduce the risk of electric shock or
re.
First, connect the power adapter to the receiver and then plug the power adapter into the
power outlet.
