The examples assume that the password has been set to 'aspi' (the default). The front panel 
password can be changed via the 
FPPSWD command. 
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved 
each time it is changed. It will retain its value after power-down. Since this command writes to non-
volatile memory, there will be a delay before an acknowledgment is returned.

users from changing the settings.

8.28. GAINA -- Set Phone Input Gain
This command sets the gain of the incoming signal from the phone interface. This command is an alias 
for the 
GAINIT command. It is provided for backwards compatibility with and ease of migration from 
the EF200. When possible, the 
GAINIT command should be used instead of this command. 
This command is an integer command. See 
Section 6.2 for more information on this type of command. 
The minimum and maximum values for this command are -100 and 20, respectively. 
This command is saved to non-volatile memory only as part of a preset. The state of this command will 
be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
