INSTALLATION GUIDELINES:
•
Install the receiver in a ventilated location where it will not be exposed to high temperatures or humidity.
•
Placing and using the unit for long periods near heat-generating sources such as amplifiers, spotlights, etc.
will affect its performance and may even damage the unit.
•
The unit can be mounted in 19-inch racks:
for this purpose a special 19” adapter (RP-WMIC) is available,
see below.
•
When installed in a booth or flight case, please make sure to minimize shocks and vibrations during
transport.
•
To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when
bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full
performance.
