IV. Safety instructions
1)
The device is equipped by fixed flex cable and can be connected only to the
alternating voltage 230 V/50H with a safety plug!
2)
Keep this device out of children!
3)
Do not use the device on humans and animals!
4)
The device can be operated at schools and at other working places only under a
control of persons trained to this effect!
5)
Do not operate the device and the connected electrical appliances without oversight!
6)
All reparations, incl. change of the damaged power flex cable have to be done only in
service designated by the manufacturer!
7)
Never use different safety fuse than is described in the instruction manual!
8)
When operating the device do not wear any jewellery, circlets and other conductive
articles!
9)
When the device is in operational mode, a dangerous voltage could appear on the
outgoing connectors.
10) Never switch-on the device immediately after bringing it from a cold environment to a
warm one. Keep it switched-off to get the same temperature as the surroundings!
11) Do not cover with anything the air vents and ventilator! In the case of infringement this
rule it could cause a damage of the device!
12) During a malfunction of the device could appear on the outgoing connectors the
voltage 290V!
