8.60. GAINP -- Set Phone Output Gain
This command sets the gain of the output to the phone interface. This command is an alias for the
GAINOT. It is provided for backwards compatibility with and ease of migration from the EF200. When
possible, the
GAINOT 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.

8.61. GAINSIT -- Set From Phone User Tone Gain
This command sets the gain of the user tones coming from the phone DSP. User tones include entry
and exit tones (see
TONEE) and custom tones (see the SOUNDP and SOUNDL commands). In most
cases, the tones are played out "locally" and their gains are adjusted by the GAINSIT command.
Sometimes, the tones are played out to the phone, and the gain is adjusted by the
GAINSOT
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.
