Profile
This command displays all the programmed settings. The HHT display
is too small to list all the command settings at one time. Therefore, this
command is most useful if the command is issued from a computer or
full-screen terminal.

This command displays or sets the TX pre-emphasis and RX
De-Emphasis when the radio is operating with the analog mode and the
radio
’
s MODEM is turned off (

radios in the system. The use of pre- and de-emphasis helps reduce the
detrimental influence of high-frequency audio noise.
