the Read 2 Key on.

When the Read 2 Key is lighted, the CPT will
locate the Search Code you have entered only
in Station 2.
HIGH SPEED SEARCH
To permit the CPT to locate any Search Code
very rapidly, the Search Codes are recorded
on the second track of the two-track tape.
It’s for this reason that only one side of the
cassette can be used for recording informa-
tion — the other side holds the Search Codes.
Because the Search Codes are recorded on a
separate track, the CPT can search at high
speed, scanning only the search codes and
ignoring the recorded information on the
other track.
On tape the Search Codes look like this:
Search Code 01 Search Code 02 Search Code 03

SEARCH CODE MEMORY
When you have entered the Search Code num-
ber to locate a Search Code, that number is
held in a memory until a different number is
entered. If you locate a document and read
it out, you can search that document again
by simply depressing the Search Key on the
console. The CPT will search for the last
Search Code entered in the memory. If you
turn off the CPT, the Search Code is lost from
the memory.
