READ DATA
During this operation, a data card is read into output
storage, to be used for new "master" card data for
duplication into the following record:
1. Operate CLEAR switch if card bed is not clear.
2. Set PROGRAM MODE to DATA READ.
3. Insert data card at punch/read station (punch or verify
mode), or feed card one cycle from hopper to pre-
register position (punch mode). Card must not
be
registered.
4. Press READ pushbutton.
The machine is automatically set to program level 0
(alpha shift) and card is stacked. Continue desired opera-
tion after setting PROGRAM MODE dial, and manually
selecting proper program level. Data from the data read
operation cannot be punched out from output storage,
except by duplication into following record.
VERIFY A CARD
Verify. procedures are normally performed under program
control:
1. Place cards to be verified in card hopper.
2. Operate CLEAR switch if card bed is not clear.
3. Set PUNCH/VERIFY switch to VERIFY.
4. Set AUTO SKIP/DUP to OFF.

5. Set REC ADV /CARD FEED to AUTO.
6. Set PRINT to ON/OFF (affects correction punched
cards only).
7. Set CHARACTER MODE to 48/64, as desired.
8. Press FEED key (feeds one card). The first card is read
and stored in input storage.
9. Set PROGRAM MODE to desired program level (1-6 or
0). Manually select desired program level by pressing
PROG SEL followed by data key 1-6 or 0 (first record
only).
Begin verify operation by keying first record from source
document. Duplicating is not active and skipping is under
manual control for the first verify record. After first record
has been verified:
10. Set AUTO SKIPjDUP to ON.
On following records, programmed verify duplicating and
skipping are perfo~ed automatically, and program level
selection at start of each record is automatic, under control
of PROGRAM MODE dial.
At completion of keying, if no errors exist, a 2· and a
3-punch are punched in column 81 of original card to
signify an OK verify without errors. If column indicator
shows 88, a field (or record) must be reverified. If column
indicator shows CC, a correction card should be punched.
Refer to "VER RES (Verify Reset) Key" and "VER CORR
(Verify Correction) Key" descriptions under "Keyboard
Controls" for error correction routines.
