Activation / Manipulation

The Q-tag CLm is activated by breaking off the green START-tab. To avoid manipulation this activation process cannot be reversed. If a device has been started by mistake it must be replaced.


The manufacturer shall not be held liable:

  • if the device was used beyond the manufacturer’s given limitations.
  • for any claims due to the improper storage and use of the device.
  • for any problems with the temperature controlling and / or cooling unit.
  • for the bad quality of any monitored goods.
  • for incorrect readings if the device was used beyond its expiry date.


The Q-tag CLm contains a CR Lithium battery. Please pay strict attention to the following points:

  • The housing of the Q-tag CLm must never be opened nor destroyed.
  • Do never expose the Q-tag CLm to temperatures above the allowed range (fire, oven, micro waves, etc.). It may cause injuries.
  • Always keep the Q-tag CLm out of the reach of children.
  • The battery complies with IATA DGR Packaging Instruction 970 Section II and is therefore not considered as dangerous good.
  • Dispose or recycle the Q-tag CLm in accordance with the WEEE 2012/19/EU guidelines or your local regulations. The device may also be returned to the manufacturer for proper recycling.
  • The end of the battery life is indicated by the expiry date printed on the label. Accuracy and proper function of the device cannot be assured beyond this date.

Useful life

The devices can be used up to 5 years after production date (expiry date printed on label) on the condition that:

  • the buttons are not pressed for very long time, e.g. if jammed between the goods in a shipment.
  • storage and operation of the device remains inside the recommendations of the manufacturer, especially very low temperatures shall be avoided.


The Q-tag CLm monitors temperature exposure and not the product quality. Its purpose is to signal if product quality evaluation or testing is required.
