The units are supplied as a pair, one MA-4230A Morse Encoder and one MA-4231 Morse Decoder and in very good condition, like new.
The MA-4230A Morse Encoder Unit enables a message to be transmitted in Morse code. The Morse message is entered using an alpha-numeric keyboard therefore no knowledge of the Morse code is necessary to operate the unit. The MA-4231 Morse Decoder decodes the Morse code being received and displays it one letter at the time on its red dot matrix display or sends it to a printer. Both units are powered by an internal rechargeable battery which provides approximately 16 hours use without recharging. The case fully sealed and waterproof.
Message entry is done via the keyboard which contains forty three Arabic alpha-numeric tactile keys, including SP space and seven function keys. Three indicators are provided showing when power is available, data is being emitted, and when the store is nearly full. The power indicator extinguishes when the battery voltage is low, and when the unit is switched off.
