Risk of explosion if the battery is replaced with an incorrect type of battery. Warning! Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery can result in an explosion. Warning! Leaving a battery in an extremely high temperature surrounding environment can result in an explo- sion or the leakage of flammable liquid or gas. Safety2.2 The trash-symbol on the product or on its packaging indicates that this product must not be disposed of with your other household waste. Instead, it is your responsibility to dispose your waste by taking it to a collection point designated for the recycling of electrical and electronic appliances. Separate collection and recycling of your waste at the time of disposal will contribute to conserving natural resources and guarantee recycling that respects the environment and human health. For further information concerning your nearest recycling center, please contact your nearest local authority/town hall offices, your household waste collection company or the shop where you bought the product. Environmental2.1 5 3.0Instrument operation The instrument is started and stopped using the power-button on the device. The button must be pressed for three seconds until the measuring LED lights up in blue, then release. The instrument starts measuring immediately when it is started. Start and stop of measurement 3.1 Each time the device is started with the power button, a new measure serie is started. This can be used to distinguish between different measurement locations. When retrieving and analyzing the data, it will be grouped by measurement series. Measure series 3.2 The device has three status-leds which will light up each time the status button is pressed.

If there are several layers in the PCB, there is an advantage to add vias for smooth interconnection of the ground areas to avoid splits in the ground plane. It is also important that there is a ground clearance around the NC pads and the RF feed pad, through all layers of the PCB. It is recommended to implement a matching network to optimize the antenna impedance in your application. The components can be positioned under the antenna. See recommendations in the figures below.
