By connecting an external keypad with a circuit as
shown below to [MIC], you can output memory content
from 4 memories. You can output memory contents
such as that from a CW Memory keyer (M1 ~ M4),
SSB/AM/FM/DV Voice Memory (T1 ~ T4) or RTTY
Memory (RT1 ~ RT4) to be transmitted.
z
Push a switch to send memory contents.
z
Hold down the switch for 1 second to repeatedly
send memory contents.
L
To use the external keypad, turn ON the following
