Each option is represented by a letter or number presented in a certain order. You can
verify the installed options by going to the options table under the System Information
(SYSINFO) menu on the front panel. You can also verify the installed options by
issuing the $PASHQ,RID command to the receiver using an external handheld
controller or PC, as described in the Z-Xtreme Technical Reference Manual. The
$PASHQ,RID command displays the options on the external handheld controller or
PC. For example:
