Dtmf Operation - Yaesu VX-1R Manual

DTMF Operation
Despite the lack of a DTMF keypad, you can still
transmit DTMF tones with the VX-IR for repeater
control or autopatch use.
Manual DTMF Tone Generation
You can generate DTMF tones during transmission
manually. The process is somewhat slow, but in an
emergency it allows tones to be sent, and with prac-
tice you can become proficient in the tone generation
procedure:
O

ting during the following steps.

digit other than 0, tum the Dial to select the number
to be sent.

sounds quietly in the speaker) for as long as you
hold in the
e

To send a string of DTMF digits manually, do not
release the PTT switch after each tone is sent. Turn
the Dial to select another number, then press

DTMF Autodialer
Eight DTMF Autodial memories are provided, allow-
ing you to store telephone numbers for autopatch use.
Each memory can hold up to 15 DTMF tones. You
