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 fully charged. The network connection is 10/10 bars. We are connected to a 2G network with the
frequency 900 MHz R means that the device is logged into the home network.
4. Put on chosen antenna.
5. The device will automatically scan the network signal once turning it on. If not,
find your way to the main menu by pressing the up- button several times. Once
pressing "Signal Scanning" you will be redirected to the second menu. Press
"Scan Signal".
6. Validate your result. The pictures below show a typical scan for a 2G, CatM1 and
CAT-NB connection.
7. By pressing the up button, you will jump to next menu. If you press the up button
multiple times you will finial enter the main menu.
8. By pressing the down button multiple times, you will rotate back to the first row in
the present menu.
9. By pressing the power button for more than 5 seconds, the device will go into
sleep mode.
10.By pressing both the up and the down key for 5 second, the device will restart.

ADDITIONAL SETTINGS
With ETM770 it is possible to make several additional settings.
Select Radio Band
1. 2. 3.
Main Menu Signal Scan Menu Select Radio Band Menu
1. Starting at the main menu, press "Signal Scanning"
2. Press "Select Radio Band"
3. Select the radio band you want to scan and press OK. By pressing the down
button, more alternatives are visible.
4. Note! When searching for CAT-NB Bands, do not scan all bands at once. This
may cause long scanning time and risk of timeout. If located in Sweden,
band20 is activated for use.
Tip! Check which bands are deployed locally in CAT-M1 and especially CAT-
NB then proceed to only select those bands in order to make scanning faster.
Once the radio band is selected you will automatically be directed back to the Signal
scan menu
Select which operator to scan amongst available operators
