Button
This button places the UT12 into CCIR manual transmit mode, automatically enters the first three tones
(820) then prompts the operator for the last two digits. Upon the second of the two status digits being
entered by the user, the UT12 will immediately key the transmitter and transmit the tone sequence. LAM
and AFN operate identically in this respect. If there is a carrier on the channel when the
button is
pressed the UT12 will operate as stated in 3.4.2.6. If the status code being sent has an associated status
message this message will be displayed as shown in the following table.
