Irreversible eye damage
Failure to do so can lead to irreversible eye damage.
▶ Follow the instructions that come with the laser safety goggles.
▶ The laser may not be operated without the handpiece being mounted.
▶ Never look into the distal end of the handpiece, laser hose coupling or the laser
hose, either with or without the laser safety goggles!

2.3.4 Safety of the construction

The KEY Laser 1243 was constructed according to the relevant safety standards
such as IEC 601 IEC 825 and VDE 0837 .
Numerous measures have been undertaken to ensure both active safety with sub‐
stantial comfort during use.
The user will not be directly aware of many of these measures:
▪ Directly after turning the device on, the microprocessor control will run a self-
check.
▪ Then a series of safety-relevant components will be operated and tested. If the
test is unsuccessful, the device will turn off again.
▪ If the test is successful, the device will go to standby mode.
▪ During operation, the proper functioning of the microprocessor control and all
safety-relevant components is continuously checked.
▪ Maximum value was placed on preventing the malfunctioning of individual com‐
ponents from endangering the physician, dental personnel, patients, or third
parties.

2.3.5 Electromagnetic compatibility

Note
Based on EN 60601-1-2 concerning the electromagnetic compatibility of electro‐
medical devices, we need to point out that:
• Medical electrical devices are subject to special measures regarding electromag‐
netic compatibility and must be operated in accordance with KaVo assembly
instructions.
• Portable and mobile high-frequency communications devices can influence me‐
dical electronics.
• More information about the technical description of EMC can be obtained upon
request.
