8.55. GAIND -- Set Gain of Incoming DTMF Tones
This command sets the gain of the incoming DTMF tones. The gain of the outgoing DTMF depends on the

COUNTRY) command. This command is an alias for the 
GAINDIT command. It is provided for backwards compatibility with and ease of migration from the EF200. 
When possible, the 
GAINDIT 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 -20 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.
