Loudspeaker button General features The Major 4a is the newer design of the well kown Major 4. The Display was replaced by an alpha- numeric LC Display with background illumination. A gooseneck microphone with high dynamics has come to it. The programming possibilities were essentially widened and strongly simplifi ed by clear text menu structure.

Connecting Major 4a (5a) --> Two-Way-Radio via multiwire All audio in/outputs of Major 4a (5a) are equiped with transformers. No PINs are grounded, therefore one must be connected to ground at the two-way-radio. We suggest to ground PIN 1 and 8 at the radio.

Hardware confi guration 2/4-wire confi guration The Major 4a (5a) is for use on 2- or 4-wire line. For 2-wire line jumper 1 have to be set. Remove jumper 1 for 4-wire line. 2-wire confi guration with FT630 For remote control of radio over longer distance it is adviceable to use a 2-wire line with the FT630.
