SAFETY INSTRUCTIONS
The product is not waterproof and should always be kept dry. Do not expose to precipitation. Do
not immerse in water or other liquids.
The meter is only used to measure air velocity and should not be used to measure the velocity
of other gases or liquids.
Always replace batteries in pairs. The utilisation of used and new batteries to supply the device
will result in its shorter operating time and can also lead to leakage of electrolyte from the
battery. Be sure to maintain proper polarity when replacing batteries. In case of storage of the
product for an extended time (over one month), remove the batteries from the product.
The device can also be powered by Ni-MH batteries. In this case a shorter operating time of the
device should be taken into account.
If the product has been stored in conditions beyond the operating conditions, wait until the
product reaches the operating conditions automatically before use.
The product is not intended to be operated by children. Make sure that children do not treat
the product as a toy.
PRODUCT OPERATION
Installing and the replacing batteries
Open the battery compartment cover. If batteries are already installed in the compartment,
remove them. Install new batteries observing the correct polarity. Replace the battery compart-
ment cover. It is recommended to use good quality alkaline batteries.
