POWER SWITCH [POWER•TIMER]

❍

While transceiver’s power is OFF:

Push to turn power ON.

• Turn the optional DC power supply ON in advance.
• A/D converter calibration of the DSP unit starts and it

takes approx. 10 sec.

❍

While transceiver’s power is ON:

➥

Push momentarily to toggle the timer function
ON and OFF. (p. 93)

•The 

[TIMER]

indicator in this switch lights while

the timer function is ON.

➥

Push for 1 sec. to turn power OFF.

w

TRANSMIT SWITCH [TRANSMIT]

Selects transmitting or receiving.

• The 

[TX]

indicator lights red while transmitting and the

[RX]

indicator lights green when the squelch is open.

e

HEADPHONE JACK [PHONES]

Accepts headphones.

• Output power: 5 mW with an 8 

Ω

load.

• When headphones are connected, the internal speaker

or connected external speaker does not function.

r

ELECTRONIC KEYER JACK [ELEC-KEY]

Accepts a paddle to activate the internal electronic
keyer for CW operation. (p. 38)

• Selection between the internal electronic keyer, bug-key

and straight key operation can be made in keyer set
mode. (p. 43)

• A straight key jack is separately available on the rear

panel. See 

[KEY]

on p. 11.

• Keyer polarity (dot and dash) can be reversed in keyer

set mode. (p. 43)

• 4-channel memory keyer is available for your conve-

nience. (p. 40)

t

MICROPHONE CONNECTOR [MIC]

Accepts the supplied or optional microphone.

• See p. 116 for appropriate microphones.
• See p. 18 for microphone connector information.

y

AF CONTROL [AF] 

(inner control)

Varies the audio output level from the speaker.

u

MIC GAIN CONTROL [MIC GAIN]

Adjusts microphone input gain.

• The transmit audio tone in SSB mode can be adjusted in

set mode. (p. 95)

✔

How to set the microphone gain.

Set the 

[MIC]

control so that the ALC meter sometimes

swings during normal voice level transmission in SSB mode.
