2.4 Dangers from invisible optical radiation

WARNING! Danger to health from invisible optical 
radiation! Irradiation of the skin close to the exit 
hole can lead to light burns.

• The red light spots are only an aid and serve to  
  focus the measuring point. They light up when the  
  equipment is configured and ready to measure.     
  The excitation beam itself is slightly blue!
• Never point the excitation beam directly at eyes  
  and skin.
• Never observe the excitation beam with optical  
  instruments such as lenses and microscopes.
• Long time exposure to radiation (over 60s daily)  
  may lead to skin damages. When working in the  
  path of the beam the use of protective gloves is  
 recommended.
• Only switch on the equipment if the sensor’s beam  
  exit hole has been tested for external damage.
• If the sensor is damaged, do not continue to use  
  the measuring equipment and send it immediately  
  to TQC Sheen.

WARNING! Danger to life from fire caused by heat 
generated by the excitation beam!The excitation 
beam can set flammable solids, liquids and gases 
on fire and cause severe to fatal injuries.

• Never use the excitation beam in areas where  
  there is a risk of explosion.
• Never point the measuring equipment at    
  flammable materials.

2.5 Dangers when handling Li-ion batteries

WARNING! The accompanying 14500 Lithium 
ion batteries are impermeable to gases and 
non-harmful as long as the manufacturers’ 
requirements for use and handling are obeyed. 
Improper handling of the rechargeable battery, 
especially mechanical damage or charging with 
an unsuitable battery charger can lead to it 
catching fire or exploding.

• Avoid mechanical and thermal stresses. Mechanical 
  damage can lead to internal short-circuits. Fire risk!
• Protect batteries from damp. In case of fire, do not  
  extinguish it with with water, but with sand, say.
• Electrolyte solution is highly flammable. Leaked  
  electrolyte solution from a Li-ion battery can be  
  washed away from the battery with water.
• Do not short-circuit Li-ion batteries. Take care  
  when using tools and wearing metal jewellery.  
• Fire risk! Excess voltage and overcharging are to be 
  avoided in all situations. The batteries should not 
  be charged close to combustible materials!
• Avoid external sources of heat such as sun, heaters  
  and fire. There is a risk of explosion.

2.6 Information for the use of the battery 
charger

The battery charger is only to be used with 
rechargeable 14500 batteries. It is recommended 
that the batteries be inserted in pairs (in 2s or 4s) 
in slots 1 and 3 and/or 2 and 4. The battery charger 
is only designed for use indoors. The operating 
temperature of the battery charger is in the range of 
0°C –40°C; heat and humidity are to be avoided.
