L

This function electronically locks the dial.

The Transmit Power Limit function limits the output

power to the preset level for each band.

1.

On the FUNCTION set screen, touch [TX PWR LIMIT].

• Each touch turns the function ON or OFF.

2. Touch [

TX PWR LIMIT

] for 1 second.

3.

Rotate

MULTI

to set the maximum transmit power.

Adjusting the transmit output

power

Before transmitting, monitor your selected operating

frequency to make sure you do not cause interference to other

stations on the same frequency. It is good amateur practice

to listen first, and then, even if nothing is heard, ask if the

frequency in use once or twice, before you start operating.

Adjusting the transmit output power

1.

Select the operating mode. (p. 3-3) (Example: USB)

2.

Touch the meter to display the Po meter. (p. 3-11)

Push

3.

Open the Multi-function menu.

5.

Touch “RF POWER.”

6.

Adjust the transmit output power to between 0 and

100%.

• The Po meter displays the RF output power in a

percentage. It becomes the S-meter while receiving.

7. Push

TRANSMIT

or release [PTT].

• Returns to receive.

Hold down

SPEECH

for 1 second to turn the

Dial Lock function ON or OFF.

• During Split Frequency operation, the Split

Lock function may be turned ON. (p. 4-10)

Rotate

AF

RF/SQL

(outer) to adjust the RF gain and

SQL level.

By default, rotating left (when set to the 12 o’clock

position) adjusts the RF gain, and rotating right

adjusts the squelch level, as described below.

RF gain

Adjust the RF gain to decrease the noise received

from a nearby strong station.

• Rotate counterclockwise to reduce the RF gain, which

reduces the receive sensitivity. “RFG” appears when

AF

RF/SQL

is set to the counterclockwise from the 11 o’clock

position. “RFG” indicates that the RF gain is reduced.

L

If a strong signal is received and “OVF” (Overflow)

appears, reduce the RF gain until “OVF” disappears.

SQL level

There are 2 types of SQL levels, depending on the

operating mode.

•

Noise squelch

Rotate the

AF

RF/SQL

(outer) until the noise just

disappears and the TX/RX indicator goes OFF.

•

S-meter squelch

The S-meter squelch disables the audio output from

the speaker or headphones when the received signal is

weaker than the specified S-meter squelch level.

Rotate the

AF

RF/SQL

clockwise from the 12 o’clock

position to increase the S-meter threshold level.

L

You can change the

AF

RF/SQL

(outer) control type in

“RF/SQL Control.” (p. 3-10)

• The Po meter level changes according

to your voice level in the SSB mode.

• The TX/RX indicator lights red and

is displayed.

to close the MENU.

Set transmit power

Limited transmit power (LIMIT value)

Even when set RF POWER exceeds

“LIMIT,” the actual output power is

limited to this value.
