l!lh){ll<B^M,H CRYPTO AG ZUG (Switzerland-Suisse) No. 3165-a Instructions for tape controlled cryptographer CX/RT These instructions are to be considered as additional ones to the basic instructions of the CX—52 which should be read carefully before starting any operation. 1 . Alterations Instead of the six key wheels, the CX/RT is equipped with a tape reader RT/CX that will control the ciphering functions of the machine by means of a perforated tape (random or key tape) which is distributed through the cipher organization. There are no internal settings to be changed at the CX—52 as the whole cipher information is supplied in the key tape. 2# Operation 2.1 Manually 2.11 Fix the bobbin support (2) (Fig.2) by sliding it from left to right onto the tape reader. 2.12 Open the tape guide cover (14) with the catch (3). 2«13 Put on the key tape and bobbin (12) and close the cover (14) (the tape will run from down upwards, the three-perforation row at the left side).
