-Note that an internal rechargeable battery keeps the key in formation stored over a very long period, even if the switch

For security reason it should however be taken care that once the unit is set to key, the power is continuously on.

4.1.1 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.
4.1.2 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).
