This command sets or queries the front panel password. This password is used in conjunction with the
FPLOCK command. The front panel must be unlocked ('FPLOCK0') in order to use this command to
set or query the front panel password. If the front panel is locked, then this command will result in
'ERROR#004'. The examples below assume that the front panel is unlocked.

8.53. 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.
Example Description Status Message
S01GAINA6
Set phone input gain to 6 dB.
S01GAINA6
S01GAINA>3
Increase phone input gain by 3 dB.
S01GAINAx , where x is the new value of the
phone input gain. If this command was issued
after the example above, then the status message
would be S01GAINA9 .
S01GAINA?
Query phone input gain.
S01GAINAx , where x is the new value of the
phone input gain. If this command was issued
after the example above, then the status message

8.54. 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
