EASURING THE SIGNAL LEVEL
This procedure allows you to check the 4G LTE/UMTS/GSM signal
level through your telephone.
Lift the handset and dial **30#.
Wait for the signal reading.
The gateway will send a number of short tones corresponding to the
signal level:
Tones
Quality
No signal
No signal
1 Tone
Low
2 Tones
Medium
3 Tones
Good
4 Tones
High
Since the signal can be subject to variations, we recommend repeating the
code **30#, 2 or 3 times a few seconds apart, in order to have a reliable
measurement.
Note: in case of low signal, we recommend installing the
gateway in a different area with a better signal.
Note: if you receive the “no signal” tone, it means that the
gateway has not been registered correctly by the
provider. We recommend trying again after a few
moments, and in case of no result, make sure that the
SIM card is working correctly.
