  10. Disposing the Product

Waste Electrical and Electronic Equipment (WEEE), Directive 2002/96/EC

This  Product  complies  with  the  WEEE  Directive  (2002/96/EC)  marking 
requirement. The affixed product label (see below) indicates that you must not 
discard this electrical/electronic product in domestic household waste. 

Product Category 

With  reference  to  the  equipment  types  in  the  WEEE  directive Annex  1,  this 
product is classified as a  Monitoring and Control instrumentation  product.

Disposing lead-storage batteries

When you throw away the batteries, be sure to cover their positive and negative 
terminals and always observe local laws and regulations. 
Insufficient  insulation  of  the  terminals  may  cause  explosion  or  fire  because 
electrical energies remain in lead-storage batteries after use.
