ACCESSORY CONNECTIONS
TX/ RX UNIT
■
Microphone (MIC)
Connect a microphone having an impedance
between 250 and 600
Ω
. As for the supplied
microphone, fully insert the modular connector into
the
MIC
jack until the locking tab clicks. You can
still utilize 8-pin metal type plug microphones,
such as MC-43S, MC-47, and MC-60A with the
optional MJ-88 adaptor (optional) if necessary.
However, do not use the MC-44, MC-44DM,
MC-45, MC-45E, MC-45DM, MC-45DME, or
MC-53DM condensor-type microphones.
■
External Speaker (EXT.SP)
On the front panel of the TX/ RX unit, there is an
external speaker jack. If an external speaker is
connected to
EXT.SP
jack, the built-in speaker on
the back of the Remote Control panel will mute.
Use only external speakers with an impedance of
4 to 8
Ω
(8
Ω
nominal). The jacks accept only
3.5 mm (1/8") diameter, 2-conductor (mono) plugs.
•
The “ ” projection indicates the external
speaker jack.
Note:
Do not connect headphones to this jack. The high audio
output of this jack could damage your hearing.
■
Keys for CW (PADDLE and KEY)
For CW operation using the internal electronic
keyer, connect a keyer paddle to the
PADDLE
jack. For CW operation without using the internal
electronic keyer, connect a straight key,
semi-automatic key (bug), electronic keyer, or the
CW keying output from a Multi-mode
Communications Processor (MCP) to the
KEY
jack. The
PADDLE
and
KEY
jacks mate with a
3.5 mm (1/8") 3-conductor plug and a 3.5 mm
(1/8") 2-conductor plug respectively. External
electronic keyers or MCPs must have a positive
keying output to be compatible with this
transceiver. Use a shielded cable between the
key and the transceiver.

The “•” projection indicates the key jack and
the “••” projection indicates the paddle jack.
Note:
Due to the functionality of the internal electronic keyer, you
may find it unnecessary to connect both a paddle and another
type of keyer unless you want to use a PC-based keyer for CW.
Refer to the “ELECTRONIC KEYER” section {page 39} to
become familiar with the internal keyer.

Headphones (PHONES)
Connect monaural or stereo headphones having a
4 to 32
Ω
impedance. This jack accepts a
3.5 mm (1/8") diameter, 2-conductor (mono) or
3-conductor (stereo) plug. After connecting the
headphones, you will hear no sound from the
internal (or optional external) speaker.
