OPERATION INSTRUCTIONS
2-2 PROANNOUNCE System User Handbook 1.1
1. To prevent the risk of fire and shock hazard, do not expose any appliance or module high humidity or water.
2. Make sure that no alien objects enter the appliances or get in contact with the modules – especially no metal parts
– since this would very likely cause dangerous electric shock and/or malfunctioning. There are no user-
serviceable parts located inside the appliances or on the modules. Opening appliance enclosures and/or rack
shelf systems can lead to dangerous shock hazard. Do not open or try to reach inside the enclosures of
appliances. Leave installation, servicing, maintenance, and any other works on the appliances or the rack shelf
system to qualified service personnel only.
3. When exposing appliances/modules to extreme temperature changes, i. e. when moving them from the outside
into a warm room, condensation may occur. If so, it is necessary to wait before use until the devices gained room
temperature.
4. Under no circumstance place any liquid-containing cans, glasses, mugs, etc. on top of an enclosure. In case any
liquids or foreign obstacles entered the enclosure of an appliance, immediately unplug the device from the mains
supply and have it serviced.
5. Make sure that appliances/modules are always provided with sufficient ventilation. Do not expose devices to
direct sunlight or any other heat-radiating source.
6. Do not expose appliances/modules to extreme dust or humidity. Operating the system under environmental
conditions like these can lead to severe damage through fire or cause bodily harm to the operator.
7. Make sure that the stated mains voltage is in accordance to the specifications of your mains supplier.
Mismatching will cause severe damage to all appliances/modules.
8. Make sure that mains cords and/or any other cabling are not damaged or being jammed by the turning frame or
any other movable parts of the rack shelf. Damaged cables can lead to fire hazard and/or can be the cause for
electric shock.
9. The mains cord of the rack shelf installation is supplied with a 3-pole plug to minimize the risk of electric shock. It
should only be connected to a grounded wall outlet. Under no circumstances insulate the ground contact. When
using an extension cord, always use a 3-pole grounded cable. When using multi-outlets for distributing, make sure
that the wall outlet's capacity is not exceeded, since this could lead to fire hazard and/or can be the cause for
electric shock.
10. The DPM 4000 contains a lithium-type battery to provide the internal clock with power. The lifetime of this battery-
type spans approximately 10 years. When the battery's voltage drops below a certain minimum, an according
message appears on the paging station display. In this case, the battery has to be exchanged by an EVI Audio
GmbH authorized service technician. Under no circumstances try to exchange the battery yourself!
CAUTION! There is a severe risk of explosion when incorrectly exchanging the battery. Only replace with
the same type of battery or one especially recommended by the manufacturer. For
environmental awareness: Take care of used batteries following the manufacturer's advice.
11. Obeying the VDE-regulation DIN VDE 0800 is necessary when installing and operating 100V-loudspeaker
systems. Especially with 100V-loudspeaker systems that are part of an emergency alert installation, protection
measures have to be in accordance with safety class 3 regulations.
CAUTION! During operation, speaker group connectors (POWER OUTPUT) may carry shock hazard output
voltages (>34V peak value). Thus, the installation of the connected loudspeaker groups has to in
accordance to security standards and regulations as stated above.
12. Make sure to establish all connections before operating the system. Connecting/disconnecting cables during
operation can cause malfunctioning or damage to the correspondent appliances.
CAUTION !
