Electronic Message Unit
The Nokia Partiosanomalaite (PARSA) is a portable military secure
Electronic Messaging Unit (EMU) for use with telephone and radio equipment.
Messages can be encrypted and decrypted with the built-in crypto system.
As the unit transmits data via AFSK (Audio Frequency Shift Keying),
It can be used over standard voice channels.
PARSA is the smaller 'brother' of the Nokia Sanomalaite (SANLA) M/90
originally released in 1983. With the Keskussanomalaite (KESANLA)
these are part of a complete integrated reconnaissance and command
messaging system (Sanomalaitejärestelmä),
including the Keskussanomalaite (KESANLA) that is in use by all branches of
the Finnish Defence Forces.

The image on the right shows a typical PARSA unit, but it should be noted
that there have been many minor manufacturing differences over the years.
Especially the keyboard and the metal rigs at the edges may differ.
This particular unit has circular keys that are part of a rubber key pad.
It has 33 keys that hold the letters of the alphabet and some special
functions. Some keys, e.g. on the upper row, have double or tripple
functions. The bottom left key is used to turn the unit on.
