Microphone Switches - Yaesu FT-2980E Operating Manual

PTT Switch

lease it to receive.
Keypad
These 16 keys generate DTMF tones

In the receive mode, these 16 keys can
be used for direct frequency entry and/
or direct numeric recall of the Memory
channels.
The [ A ] , [ B ] , [ C ] , and [ D ] keys, on re-
ceive, replicate the functions of the front
panel keys ([ MHz ( SET )] , [ REV ( DW )] ,
[ LOW ( A/N )] , and [ D/MR ( MW )]) . See
the previous discussion.
[ P1 ] / [ P2 ] / [ P3 ] / [ P4 ] Buttons
These four keys are user programma-
ble, allowing quick access to features
used often. The default functions are
described below.

channel bank. In the Asian/European version, pressing this button acti-
vates T.CALL (1750 Hz) for repeater access.
You can reprogram the [ P1 ] , [ P2 ] , [ P3 ] , and [ P4 ] buttons for other func-
tions, if desired. See page 56 for details.
