MFJ-432 Voice Memory Keyer
5
Accessory Circuits
Many circuits can be added to the accessory port to implement different functions. Each
message line is available on this port along with +5 Vdc. The message line must be
asserted high, to 5 Vdc, in order to play a message.
Implementing a Remote:
One of the simplest circuits to implement for the Voice keyer
is a remote. A remote requires 4 momentary contact SPST
switches, a length of 5 conductor cable, a 5 pin IDC connector
and a small box to hold the switches.
Battery Installation and Removal
This unit can be used with a 9 volt battery for mobile operation. Remove the cover to
begin battery installation. Slide the plastic battery clip insulator down on the wire and
install the battery. Press the battery into the battery holder and replace the cover.
