preference.
The friction adjustor is located under

.
See the illustration below.
Slide the adjustor for a comfortable friction level
while continuously and evenly turning the dial in one
direction.
Using the SPEECH function
The transceiver has a built-in Voice synthesizer to
announce the operating frequency, mode, as well as
the S-meter level in a clear electronically-generated
voice, in either English or Japanese.
First, set the following items in the SPEECH screen.
MENU
» SET > Function > SPEECH

z Push
SPEECH
to announce the currently selected
frequency, mode*, and S-meter* level.
* If set to ON, the Mode and S-meter level are
announced.
Measuring SWR
The transceiver has a high-performance SWR
meter. This meter displays a stable measurement in
real time, even if the transmit output power varies
frequently, such as during an SSB mode operation.
You can measure the SWR of an antenna itself
through the internal antenna tuner.
There are 2 ways to measure SWR, one is spot
measurement and the other is plot measurement.
D Spot measurement
1. Push
TUNER
to turn OFF the antenna tuner.
L Perform this step if the antenna tuner is
connected and you want to measure the SWR
of the antenna itself.
2. Select the RTTY or RTTY-R mode.
3. Set the desired frequency band and a frequency
in the portion of the band that you use the most.
4. If necessary, adjust the RF power to more than
30 W in the Multi-function menu.
• 70 MHz: 20 W
( 70 MHz band transmission may be possible,
depending on the transceiver version.)
5. Touch the TX meter several times until the SWR
meter is selected. (p. 3-11)

Friction adjustor
NOTE: Before transmitting, monitor the operating
frequency to make sure you will not cause
interference to other stations on the same
frequency.
6. Push
TRANSMIT
or hold down [PTT] on the
microphone to transmit.
7. Read the SWR on the meter.
L If the SWR meter indicates 1.5 or less, the
antenna is matched.
8. Push
TRANSMIT
or release [PTT] to stop transmitting.
L If the measured SWR is more than 1.5:1,
push [TUNER] to match the antenna with the
transceiver.
SWR meter
The best match is within this range.
