Nvinit -- Reinitialize Non-Volatile Memory; Nvlock -- Lock/Unlock Non-Volatile Memory - Polycom Vortex EF2211 Programming Manual

cancel 10 dB of noise. Higher numbers mean more cancellation will be applied, but may result in slight
artifacts depending on the characteristics of the noise. Typical settings are 10 dB for normal
cancellation and 6 dB for light cancellation.
When the wildcard character, '*', is used to specify the channel in this command, it only affects input
channel 1. To set or query the telephone input channel, T, you must specify it explicitly (e.g., '' ''
'S01NCLT6', '' '' 'S01NCLT?').
This command is a channel integer command. See
on this type of command. The minimum and maximum values for this command are 0 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
Set NC attenuation level on input channel 1 to
S01NCL13
3 dB.
Query the NC attenuation level on input
S01NCL1?
channel 1 .
Set NC attenuation level on all microphone
S01NCL*6
input channels (only 1 on EF2211) to 6 dB.
Query NC attenuation level on all microphone
S01NCL*?
input channels (only 1 on EF2211) .

8.111. NVINIT -- Reinitialize Non-Volatile Memory

This command reinitializes (or formats) all non-volatile memory settings. This will effectively erase
settings for global settings, user presets, macros, labels, and logic I/O configurations. This will
basically reset the unit to a "fresh-out-of-the-box" state.
When this command is issued, it writes to non-volatile memory in order to format the contents back to
the factory default state. The writing process results in a short delay. After the non-volatile memory
has been reformatted, the Vortex will perform a software reset, which is equivalent to a power cycle.
Example Description
Reinitialize non-volatile memory and perform a
S01NVINIT
software reset.

8.112. NVLOCK -- Lock/Unlock Non-Volatile Memory

Section 6.3 and Section 6.2
Status Message
S01NCL13
S01NCL1x , where x is a number
between 0 and 20, depending on the
current setting of the NC attenuation
level on input channel 1 .
S01NCL*è
S01NCL*x, where x is between ä and ÿ,
depending on the current setting of the
NC attenuation level for input 1.
Status Message
No status message will be generated.
There will be a short delay and then
the Vortex will reset.
