Product Overview

Get started

Get started scanning a signal with ETM770

1. Insert SIM card as shown in picture above.
2. Insert the charger into the mini USB connector. The battery is charged with 5V.
3. To turn the device on, press the power button for a minimum of 3 seconds. When the device is turned on and the charger is successfully connected, the screen shall look as follows:
   • The battery is almost fully charged. The network connection is 8/10 bars. We are connected to a 4G network with the frequency 2600 MHz. R means that the device is logged into the home network.
4. Put on chosen antenna.
