INSTALLING AND CONNECTING THE TRANSCEIVER 1
Index Contents
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 5-18}
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}
