7. Location of equipment
Observe the following points:
The maximum range of the wireless signal is typically 100m in free space
(and up to 200m in optimal conditions) with line of sight contact between
transmitter and receiver. Within buildings the range is greatly reduced by
walls and floors, in particular those made of metal or steel reinforced
concrete, to a maximum of 20m. Metal housings, shelves, mirrors and
water masses also block the wireless signal.
If the wireless connection is weak or non-existant between the locations of
the source and display devices then first try adjusting the antennas and
moving the transmitter and the receiver. If necessary, extension cables can
be used between these devices and the DF-120 components to enable
these to be located such that there is wireless connection. Use A/V
extension cables or for CCTV applications use RG59, 75 Ohm coaxial cable
with the necessary BNC connectors (see chapter "Optional Accessories").
The wireless transmission can also be affected by strong electric fields and
other wireless equipment. Ensure an adequate distance of the transmitter
and receiver to microwave ovens, cordless phones, mobile phones, wireless
devices in the 2.4GHz frequency band (WiFi), electric motors and high
voltage devices or power cables.
The devices must be placed on a solid and level surface, ideally a minimum
of 1m above the floor (optimal reception). They can be located nearby a TV
set or monitor, however not directly on top of the casing otherwise the

ception quality can be reduced. Locate the devices away from metalic
objects and steel reinforced concrete as these reduce the wireless range.
When using an infrared remote control make sure that the infrared
transmitter window on the DF-120 TX is pointing at the infrared window of
the source
window of the DF-120 RX (see Fig. D).
Ensure that the location is free of excessive dust, vibration and excessive
heat.
There should be suitable mains outlets in the vicinity.

6. Safety instructions
The following instructions are provided for your safety and satisfaction during
operation of the device. Note that non-observance of these safety instructions
results in significant risks of accident.
If this point is not heeded life and health is endangered.
Do not leave small children unsupervised with the device, cables,
packaging material or small parts. Otherwise there is a risk of fatal injury
due to choking, strangulation or suffocation.
Treat the cables carefully. Lay these so that they cannot be damaged and
do not present any tripping hazard. Otherwise there are dangers of fire,
personal and fatal injury.
Prevent the device from coming into contact with moisture and do not
submerge in water. Otherwise there is a danger of fatal injury.
Only operate the device from the supplied power supply. Before
connecting the power supply to the mains, ensure that the mains current
complies with 230 V ~, 50 Hz and is fitted with a fuse according to
regulations. Otherwise there are dangers of fire and fatal injury.
Non-observance of these instructions puts property at r i s k
of damage.
Do not place the equipment near fire, heat or in areas of high
temperature.
Protect the equipment and the cables against strong magnetic or
electrical fields and against strong mechanical loads and vibrations.
Only use the equipment with the supplied original parts or original
accessories.

Before installing and operating the product check the package for
damages and completeness.
If the unit is to be unused for a longer period, disconnect the mains
adapter from the mains supply and remove the batteries.
Do not connect any damaged device (e.g. transport damage) and
disconnect the power supply immediately in the case of damage. Unplug
the mains adapter from the mains socket. Arrange for the damage to be
repaired immediately by a specialist!
