AuxComm Setting - Power on at Boot-up
This setting determines whether or not the AuxComm module is turned on when the
instrument is powered on. In addition to power savings, this setting is also intended for use
when a user has a need for “radio silence” (no RF broadcasts). This setting does not override
the hot-key (Figure 15) function. Again, the primary use for this parameter is while using
Bluetooth®. Table A-4 shows valid settings.
Note:
This setting should be 0 when using any of the 375 modes.

AuxComm Setting - Write Protect
This setting is an additional security measure that prevents commands that would modify
parameters from being executed over the AuxComm port. While using the instrument
equipped with a wireless radio, such as the Bluetooth module, there is the potential for the
instrument becoming mis-configured, inadvertently or intentionally, from a remote location.
This setting is meant to ensure that cannot happen. Table A-5 shows valid settings.
Note:
This has no effect in 375 modes.
