The default out of the box is a simple mode display. Is this still too much information on the Menu display for them?
From the owners manual:
"Simple Display
PSR-800 User Manual Page 68
By default, the PSR-800 operates with a simplified display that
only shows object and Scanlist names. To see more information
about objects, disable this option. This option must be
unchecked to view detailed frequency, talkgroup ID, Radio ID or
CTCSS and DCS squelch code information."
