■ Maximum Recording Time for the Memory Function
• Because data is not recorded directly to the CF card, maximum recording time is independent of CF card
capacity. Maximum recording time is determined only by internal memory capacity.
• Operation cannot be guaranteed when recording continuously for more than one year (with a slow timebase).
• Maximum recording length is the same whether using one or two channels.
