Protecting your instrument from strong RF fields

If you are like us, the first thing you want to do is to power up your unit and play with it. This is perfectly ok; just make sure you are not near any strong RF field before plugin in your antenna in the SMA connector. At very same instant you plug in the antenna, the device will start receiving RF energy even if it is powered off. This is not much of an issue if you are using a 6G Combo, a 3G Combo or WSUB1G PLUS, but some basline RF Explorer models like WSUB1G are protected from moderate RF signals only, not against very strong fields.

Please read this article for more details on how to protect your device from strong RF fields. Failing to do so may damage your RF Explorer.

Using the internal battery 

This is a battery operated device, please charge the battery fully before use; it comes with half charge as the standard way to extend the battery life when it is stored for an undetermined period of time on the warehouse. But to use it you should fully charge it. Never charge your device unattended.

As recommended in the user manual, a first full charge and battery calibration procedure is recommended to correctly use your device. More details on this article

Note the device will automatically switch ON as soon as you plug it in the USB port, but that doesn't mean it is being charged: to charge the battery you need to switch the battery power to ON. There are more details on this FAQ article, including battery handling and care information.

Firmware upgrade

We suggest upgrading your unit to the very latest firmware available. Everything is available in the download area and full instructions are available on this article.
