INSTALLING AND CONNECTING THE TRANSCEIVER 1 MICROPHONE (MIC) The MIC jack accepts a microphone with an impedance of 250Ω to 600Ω. Connect the microphone plug to the MIC socket on the front panel and screw the retaining ring until the microphone is securely tightened. The following optional microphones can be used with this transceiver: • MC-43S • MC-60A • MC-90 • MC-47 The following microphones cannot be used with this transceiver. • MC-44 • MC-44DM • MC-45 • MC-45DM PADDLE (PADDLE) For CW operation using the built-in electronic keyer, connect a keyer to the PADDLE jack. The PADDLE jack accepts a 3-conductor plug with a 6.3 mm (1/4") diameter. The straight key can be connected to the PADDLE jack. In this case, select "Straight Key" from Menu 5-00, "Paddle Jack Configuration (Front)". {page 5-19} USB FLASH DRIVE/USB KEYBOARD ( ) You can connect any commercially available USB flash drive or USB keyboard to the USB-A port. Connect it securely to the (USB-A) port. Note: ◆◆Do not disconnect the USB flash drive from the transceiver while it is in use, such as while reading or writing data. Additionally, do not turn the main power switch (I/O) OFF. {page 12-1} ◆◆To avoid any damage to the data, you must remove the USB flash drive after executing Safe Removal of USB Flash drive. {page 12-1} ◆◆Only a USB flash drive or a keyboard can be connected to the USB connector. EXTERNAL SPEAKERS (EXT.SP1/EXT.SP2, 8Ω) The transceiver is equipped with two independent receivers. In general, audio from both receivers sounds from the internal speaker. However, connecting an external speaker allows you to separate the audio outputs. On the rear panel, two jacks for external speakers are available, allowing you to connect two external speakers. An external speaker with an impedance of 4Ω to 8Ω (standard is 8Ω) can be connected using the 2-conductor (mono) plug with a 3.5 mm (1/8") diameter. If an external speaker is connected to EXT.SP1, no audio sounds from the internal speaker. If an external speaker is connected to EXT.SP2, the audio sounds from both the external speaker and the internal speaker. Note: ◆◆The EXT.SP1 and EXT.SP2 jacks with 8Ω impedance are dedicated for external speakers. Do not connect headphones to these jacks. Doing so will result in a high audio volume level which may cause an auditory disorder. ◆◆Audio to sound from an external speaker can be selected from the menu. {page 16-17} Audio Device with an Optical Digital I/O Terminals Straight Key (Commercially available) Optical Digital Cable (Connect one piece each for input and output) External Speaker (Optional) Paddle (Commercially available) Main Band Meter Sub Band Meter 3 1 S PO SWR Id COMP 579 +20 +60dB 3 250W 5 10 ∞ 10 20 15A dB ALC 44 52V vd 3 1 S PO SWR Id COMP 579 +20 +60dB 3 250W 5 10 ∞ 10 20 15A dB ALC 44 52V vd Add a resistor as necessary Meter (Commercially available) Contents Index REAR PANEL Φ3.5 mm stereo To DVI port DVI cable (E type) 1-3

Index
Contents
MICROPHONE ±MIC²
The MIC jack accepts a microphone with an impedance of
250Ω to 600Ω.
Connect the microphone plug to the
MIC
socket on
the front panel and screw the retaining ring until the
microphone is securely tightened.
The following optional microphones can be used with this
transceiver:
MC³43S
MC³60A
MC³90
MC³47
The following microphones cannot be used with this
transceiver.
MC³44
MC³44DM
MC³45
MC³45DM
PADDLE ±PADDLE²
For CW operation using the built-in electronic keyer,
connect a keyer to the
PADDLE
jack. The
PADDLE
jack
accepts a 3-conductor plug with a 6.3 mm (1/4") diameter.
The straight key can be connected to the
PADDLE
jack. In
this case, select "Straight Key" from Menu 5-00, "Paddle
Jack Configuration (Front)".
{page 5-19}
USB FLASH DRIVE/USB KEYBOARD ±
²
You can connect any commercially available USB flash
drive or USB keyboard to the USB-A port.
Connect it securely to the
(USB-A) port.
Note:
Do not disconnect the USB flash drive from the transceiver while it
is in use, such as while reading or writing data. Additionally, do not
turn the main power switch (
I/O
) OFF.
{page 12-1}
To avoid any damage to the data, you must remove the USB flash
drive after executing Safe Removal of USB Flash drive.
{page 12-1}
Only a USB flash drive or a keyboard can be connected to the
USB
connector.
EXTERNAL SPEAKERS ±EXT.SP1/EXT.SP2, 8Ω²
The transceiver is equipped with two independent
receivers. In general, audio from both receivers sounds
from the internal speaker. However, connecting an
external speaker allows you to separate the audio outputs.
On the rear panel, two jacks for external speakers are
available, allowing you to connect two external speakers.
An external speaker with an impedance of 4Ω to 8Ω
(standard is 8Ω) can be connected using the 2³conductor
(mono) plug with a 3.5 mm (1/8") diameter.
If an external speaker is connected to
EXT.SP1
, no audio
sounds from the internal speaker.
If an external speaker is connected to
EXT.SP2
, the audio
sounds from both the external speaker and the internal
speaker.
Note:
The
EXT.SP1
and
EXT.SP2
jacks with 8Ω impedance are
dedicated for external speakers. Do not connect headphones to
these jacks. Doing so will result in a high audio volume level which
may cause an auditory disorder.
Audio to sound from an external speaker can be selected from the
menu.
