2 VOICE CIPHER EQUIPMENT CRYPTOCOM CRM-008 (previously CV-008) Short Form Instructions I. INTRODUCTION The CRM-008 is a voice cipher equipment intended for use over any telephone channel according to CCITT standards, as well as over good SSB radio links with full 3000 Hz c a p a c i t y. I t i s u s e d i n h a l f - d u p l e x m a n n e r. The CRM-008 is, in telephone service, connected with an adapter switch to the telephone set. Once the communication is established as usual, the two partners switch over to CRM-008. To improve the speech quality, the u n i t i s e q u i p p e d w i t h i t s o w n h i g h - fi d e l i t y - v o i c e h a n d s e t, as in most public telephone systems, microphone as well as earphone cartridges are of a relatively poor grade. Modern handsets with magnetic microphones are however usuable, but they should be equipped with a push-to-talk switch. In radio operation the CRM-008 is hooked up at audio-in/ output connections with custom made adapters(i.e.microphone plugs etc.) or at the X-mode connector, depending on the radio system. The radio station is then operated as usual by means of the separate handset or the original audio gear ( s p e c i a l o p e r a t i o n i n s t r u c t i o n s a r e s u p p l i e d f o r t h e d i f f e r e n t r a d i o s t a t i o n s a f t e r c l a r i fi c a t i o n o f t h e m o d e l i n v o l v e d ).

3 CONNECTION 2,1 Information Path WIRE CONNECTION (see Fig. 2) LINE_SIDE Connect the data-plug (1) (see Fig. 1) connector poles "3" and "8" together to one wire and the connector "2" to the other one. These two wires are fed via a insulation transformer to the tele phone line (either directly or by means of a switchover box) LOCAL SIDE (separate handset) Connect the supplied handset to the plug (10). All connections are automatically performed RADIO CONNECTION F o l l o w t h e s e p a r a t e i n s t r u c t i o n s s u p p l i e d w i t h t h e a d a p t e r k i t f o r y o u r r a d i o s t a t i o n PUBLIC TELEPHONE CONNECTION F o l l o w t h e s e p a r a t e i n s t r u c t i o n s s u p p l i e d w i t h t h e s w i t c h - o v e r - adapter-box. 2.2 Power Connect at the rear the power supply cable and its other end to

Be sure to set the selector first to the voltage of your mains power outlet before connecting the unit. 2.3 AFC In radio connections standard mode is "0". In telephone connec t i o n s l e a v e i t a l s o o n p o s i t i o n " 0 ".

They are subdivided into 8 groups of 4 digits. Each group will be selected by its number from 1 to 8 Each group can individually be entered, without disturbing the rest I

5 T u r n s w i t c h ( 7 ) t o p o s i t i o n " k e y " S e t t n e k e y a s f o l l o w s : EXAMPLE Group 1: Push button 1 (this is the group number). Push now the buttons 4, 5, 7, 2 (these are the 4 digits). (If one digit happens to be needed more than once, then push its button so many times as needed.) T h e d i s p l a y s h o w s n o w : To enter the group number and the 4 digits, push button #. Group 2: Push button 2 (this is the group number). Push now the buttons 1, 8, 9, 1 (these are the 4 digits). T h e d i s p l a y s h o w s n o w : To enter the group number and the 4 digits, push button Vf. Go ahead up to group 8. T h e s e q u e n c e o f fi l l i n g - i n t h e g r o u p s i s c o m p l e t e l y f r e e. A n y group can be replaced at any moment. The group is identified only by the digit in front of the four number sequence. If a wrong push button has been hit, cancel the whole group information with button * and start again with the group num b e r d i g i t. 3, 3 T u r n s w i t c h ( 7 ) b a c k t o " o f f " o r " P " o r " C ", d e p e n d i n g i f t h e station must immediately be used or will be resting for a cer tain time.

6 HAGEUN-CRYPTOS Note that an internal rechargeable battery keeps the key in formation stored over a very long period, even if the switch (7) is in off-position. For security reason it should however be taken care that once the unit is set to key, the power is continuously on. 4. OPERATION (direct connection, without switchover box) 4.1 Plain Turn switch (7) to "P". The unit is switched on and at the dis play the dash is lit, acting as an indicating signal that the CRYPTOCOM is operative Push switch at handset and talk to the opposite station. The red signal (2) will be blinking. Be sure to close your "turn" with the word "over" and release the talk switch. The other station will reply in the same manner. In plain operation the unit injects in intervals of about 4 seconds an audible bip of 1200 Hz into the line as warning signal. Note that the information processing adds a certain delay into the voice path (this delay is shorter in PLAIN than in CRYPTO mode). Be therefore patient awaiting an answer from opposite station. D_0_ N_ 0 T_ call immediately again after you have said "over" and released the talk switch (in fact, if both stations are sending at the same time3 it would never be possible to correspond).

7 L\,2 Crypto For Crypto operation all corresponding stations must be set to the same key. Make sure with the officer in charge of the cipher procedure that you have in fact the right keys stored in your equipment A f t e r a g r e e m e n t w i t h t h e o p p o s i t e s t a t i o n, t u r n s w i t c h ( 7 ) t o position "C" O p e r a t e t h e u n i t s e x a c t l y a s i n p l a i n. A t t h e s e n d i n g s t a t i o n the lamp (2) will be continuously on as long as the talk-switch is pushed. (Be sure to always end your "turn" with the word " o v e r " b e f o r e r e l e a s i n g t h e t a l k s w i t c h. ) A t t h e r e c e i v i n g s t a t i o n t h e l a m p ( 3 ) i s fl i c k e r i n g i f t h e s y n c c a r r i e r i s d e t e c t e d a n d w i l l b e c o n t i n u o u s l y o n a f t e r the unit has correctly synchronized into the key sequence. (Note, that the sync signal may also be on if wrong keys had been selected. In fact, the unit has not the capacity to check the correct key selection, but is only able to mesh into a given synchronisation sequence.) Note, that the selector switch (7) does only affect the send o p e r a t i o n, i. e. a s t a t i o n c a n e i t h e r r e c e i v e i n p l a i n o r c r y p t o, i n d e p e n d e n t l y o f t h e p o s i t i o n o f s w i t c h ( 7 ) ( i t m a y b e e i t h e r on "P" or "C").
