If you have questions which remain unanswered by this information product, contact our technical support service or other technical personnel.

Maintenance, modifications and repairs must only be completed by a techni- cian or an authorised repair centre.18

Handle the product carefully. Jolts, impacts or a fall even from a low height can damage the product.

6.3 Operating environment

Do not place the product under any mechanical stress.

Protect the appliance from extreme temperatures, strong jolts, flammable gases, steam and solvents.

Protect the product from direct sunlight.

Consult an expert when in doubt about the operation, safety or connection of the product.

If it is no longer possible to operate the product safely, take it out of operation and protect it from any accidental use. DO NOT attempt to repair the product yourself. Safe operation can no longer be guaranteed if the product: – is visibly damaged, – is no longer working properly, – has been stored for extended periods in poor ambient conditions or – has been subjected to any serious transport-related stresses.

Correct polarity must be observed while inserting batteries.

The batteries should be removed from the device if it is not used for a long period of time to avoid damage through leaking. Leaking or damaged batteries might cause acid burns when in contact with skin, therefore use suitable pro- tective gloves to handle corrupted batteries.

Batteries must be kept out of reach of children. Do not leave batteries lying around, as there is risk, that children or pets swallow them.

All batteries should be replaced at the same time. Mixing old and new batteries in the device can lead to battery leakage and device damage.

Batteries must not be dismantled, short-circuited or thrown into fire. Never re- charge non-rechargeable batteries. There is a risk of explosion!19 7 Overview

Symbol Description Display hold active. Auto shut-off active. Low battery indicator. MAX Maximum value is held. MIN Minimum value is held. AVG Average value is displayed. dBA A-Weighted decibel scale (human hearing). dBC C-Weighted decibel scale (flatter frequency response).20 Symbol Description FAST Fast time evaluation. SLOW Slow time evaluation.

Measurement range exceeded. 8 Replacing batteries Note: Replace the batteries when the low battery indicator shows.

1. Use a cross-head screwdriver to remove the compartment cover screw.

3. Replace the battery compartment cover taking care not to over-tighten the

Press and hold the button to switch the power ON/OFF.

Notes: – Auto shut-off is active by default, it is indicated by the " " symbol. – This energy saving feature will shut power off after approximately 15 minutes of no activity. To disable auto shut-off: Preconditions:

The power is switched ON.

1. Short press the HOLD button and then short press the button .

à The symbol will disappear when disabled.

2. Auto shut-off will reactivate after the power is switched OFF.21

9.3 MAX / MIN / AVG display

In this mode the display shows the "MIN" (minimum), "MAX" (maximum), or "AVG" (average) value measured.

Press the "MAX MIN" button repeatedly to toggle though modes: MAX → MIN

The display will show "MAX", "MIN", or "AVG" to indicate which mode is active.

Important: – The display hold function freezes the display. – The display hold should be switched OFF before taking measurements.

Notes: – "dBA" is the A-weighted decibel scale that approximates human hearing by reducing the emphasis on very low and very high audio frequencies. – "dBC" is the C-weighted decibel scale that measures sound levels with a flat- ter frequency response across the audible spectrum compared to the A- weighted scale.

Press the MODE button to switch between weighted scales.

The display will show "dBA" or "dBC" to indicate which mode is active.22

9.6 FAST / SLOW response time

Notes: – Fast time evaluation "FAST" uses a 125 ms time constant. It responds quickly to fluctuations in sound levels and is good for capturing short, transi- ent sounds (e.g., hammering, dogs barking, drums etc.). – Slow time evaluation "SLOW" uses a 1 sec time constant. It responds more slowly, and is good for measuring steady, continuous sounds (e.g., ma- chinery noise, fans, AC systems, crowd noise etc.).

Press and hold the MODE button to toggle between "FAST" and "SLOW" re- sponse times.

The display will show "FAST" or "SLOW" to indicate which mode is active.

You cannot change response times when " " is active. 10 Sound measuring tips

Make sure there are no objects between the microphone and the sound source.

To not influence the sound waves, extend the microphone away from the body using an outstretched arm or mount it to a stand.

If possible, move approx. 2 m away from the sound source.

Minimize device vibration or movement.

Wind noise affect results, use the included foam suppressor if the wind speed >10 m/s.23 11 Cleaning and care Important: – Do not use aggressive cleaning agents, rubbing alcohol or other chemical solutions. They damage the housing and can cause the product to malfunc- tion. – Do not immerse the product in water.

1. Clean the product with a dry, fibre-free cloth.

This symbol must appear on any electrical and electronic equipment placed on the EU market. This symbol indicates that this device should not be disposed of as unsorted municipal waste at the end of its service life. Owners of WEEE (Waste from Electrical and Electronic Equipment) shall dispose of it separately from unsorted municipal waste. Spent bat- teries and accumulators, which are not enclosed by the WEEE, as well as lamps that can be removed from the WEEE in a non-destructive manner, must be removed by end users from the WEEE in a non-de- structive manner before it is handed over to a collection point. Distributors of electrical and electronic equipment are legally obliged to provide free take-back of waste. Conrad provides the following return options free of charge (more details on our website):

in our Conrad offices

at the Conrad collection points

at the collection points of public waste management authorities or the collection points set up by manufacturers or distributors within the meaning of the ElektroG End users are responsible for deleting personal data from the WEEE to be dis- posed of.24 It should be noted that different obligations about the return or recycling of WEEE may apply in countries outside of Germany.

12.2 (Rechargeable) batteries

• Remove batteries/rechargeable batteries, if any, and dispose of them separately from the product. According to the Battery Directive, end users are legally obliged to return all spent batteries/rechargeable batteries; they must not be disposed of in the normal household waste. Batteries/rechargeable batteries containing hazardous substances are labelled with this symbol to indicate that disposal in household waste is forbidden. The abbreviations for heavy metals in batteries are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable) bat- teries, e.g. below the trash icon on the left). Used (rechargeable) batteries can be returned to collection points in your municip- ality, our stores or wherever (rechargeable) batteries are sold. You thus fulfil your statutory obligations and contribute to environmental protection. Batteries/rechargeable batteries that are disposed of should be protected against short circuit and their exposed terminals should be covered completely with insu- lating tape before disposal. Even empty batteries/rechargeable batteries can con- tain residual energy that may cause them to swell, burst, catch fire or explode in the event of a short circuit.25 13 Technical data Power supply p. 3
