ACCESSORY CONNECTIONS

FRONT PANEL

■ Headphones (PHONES)

Use headphones having 4 to 32 Ω impedance. You

can also use stereo headphones. When

headphones are used, no sound is heard from the

internal (or optional external) speaker. Use a 6.0 mm

(1/4") diameter, 2-conductor (mono) or 3-conductor

(stereo) plug.

■ Microphone (MIC)

To communicate in the voice modes, connect to the

MIC connector a microphone having an impedance

between 250 Ω and 600 Ω. Insert the connector

from your microphone fully, then screw the retaining

ring clockwise until snug. Compatible microphones

include the MC-43S, MC-60A, MC-80, MC-85, and

MC-90. Do not use the MC-44, MC-44DM, MC-45,

MC-45E, MC-45DM, or MC-45DME microphone.

■External Speaker (EXT SP)

Ensure any external speaker used has an impedance of 8 Ω. Use a 3.5 mm (1/8") diameter,

2-conductor (mono) plug. When an external speaker is used, no sound is heard from the internal speaker.

WARNING! Do not connect headphones to this jack. The high audio output at this jack could damage your hearing.

■Keys and Keyboards for CW Operation (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 keyed output from a Multimode Communications Processor (MCP) to the KEY jack. The jacks mate with a 6.0 mm (1/4")

3-conductor plug and a 3.5 mm (1/8") 2-conductor plug respectively. External electronic keyers or MCPs must use positive keying to be compatible with this transceiver. Use a shielded cable between the key and the transceiver.

Note: Due to the full-featured functionality of the internal electronic keyer, you may decide itÕs unnecessary to connect both a paddle and another type of key unless you specifically want to use a keyboard for CW. ItÕs recommended that you become familiar with the internal keyer by reading ÒELECTRONIC KEYERÓ {page 32} before making your decision.
