BASIC OPERATION
■ Volume setting
➥ Rotate the [AF] control clockwise to increase the
audio output level, counterclockwise to decrease it.
■ Voice synthesizer operation
The IC-9100 has a built-in voice synthesizer to an-
nounce the operating frequency, mode and S-meter
level in clear, electronically-generated voice, in English
(or Japanese).
First, select the desired parameters to be announced
in the Set mode. (p. 164)
Initial values for the voice synthesizer parameters
•SPEECHLevel :50%
•SPEECHLanguage :English
•SPEECHSpeed :HIGH
•SPEECHS-Level :ON
•SPEECH[MODE]SW:OFF
•[SPEECH/LOCK]SW:SPEECH/LOCK
(See NOTE as described below.)
➥ Push [SPEECH/LOCK] to announce the currently
selected frequency, mode and S-meter level*.
* The S-meter level announcement can be turned OFF. (p.
164)
NOTE: If “SPEECH/LOCK” is not selected in the
“[SPEECH/LOCK] SW” item of the Set mode,
you should hold down [SPEECH/LOCK] for 1
second to activate the voice synthesizer. (p. 164)
➥ Push a mode switch to announce the appropriate
mode, when the “SPEECH [MODE] SW” item is set
to “ON” in the Set mode. (p. 164)

•SWR :Displays the SWRoftheantenna atthefre-
quency.
•ALC :
Displays the ALC level. When the meter move-
ment shows the input signal level exceeds the
allowable level, the ALC limits the RF power. In
such cases, decrease the microphone gain level.
•COMP:Displays the compression level when the
speech compressor is in use.
