1. How do I find out the GSM signal level?

The GSM signal level is shown in the Status page under the GSM column.

2. How do I interpret the GSM signal level?

The table below shows the meaning of the signal level. It is recommended that the signal level should be 15 or above in order to get good voice quality and reliable operation. If the signal level is too low, it may affect the ASR (Answer Seizure Rate). If you get a poor signal reception of a GSM channel, you should try to move it to a location with better signal reception or use an external antenna with an extended cable. Other method to improve on the antenna gain could also be used. If you get a signal level of 99, it could mean that there is no GSM coverage or the GSM registration fails.
