qRS-232C CONNECTOR (p. 10)

Connects an RS-232C cable. An RS-232C cable can be used to connect the IC-R8500 to a PC. In this way commands can be sent to the receiver via the PC.

wCI-V REMOTE CONTROL JACK (p. 10)

Allows connection to an Icom CI-V system trans- ceiver or another receiver for the transceive function. Also connects to a PC with several receivers for command control via an optional CT-17 CI-V LEVEL

CONVERTER.

eIF OUT JACK (p. 40)

Outputs a 10.7 MHz IF signal with 9 V DC for an op-

tional TV-R7100TV RECEIVE ADAPTER.

rAGC JACK (pgs. 16, 40)

This jack has functions which are selectable through

internal receiver settings.

• Outputs an AGC signal for an optional TV-R7100 TV RE-

CEIVE ADAPTER (default).

Outputs audio detected signal without de-emphasis for 9600 bps data detection (FM mode only).

tDC 13.8 V JACK (p. 8)

Plug in the jumper connector here when using the supplied* AC adapter.

Connects to a 13.8 V DC power source using the supplied DC cable when the AC adapter is not connected.

*Not supplied with some versions.

yEXTERNAL SPEAKER JACK Connects an 8 Ω external speaker.

When an external speaker is connected, the internal speaker does not function.

uDC IN JACK (p. 8)

Connects the supplied* AC adapter.

A regulator circuit has been designed between this con- nector and the DC 13.8 V jack.

Be sure the jumper connector is connected to the DC

13.8 V jack.

*Not supplied with some versions.

iHF 50 Ω ANTENNA CONNECTOR (p. 8)

Connects an antenna to cover the frequency range below 30 MHz.

Use a coaxial cable and a PL-259 connector.

Be sure this connector is selected in quick set mode (p. 31).

oGROUND TERMINAL (p. 9) Connect this terminal to a ground.

!0HF 500 Ω ANTENNA CONNECTOR (p. 8)

When a 500 Ω long wire antenna is used for HF band receiving, this connector is used instead of the 50 Ω antenna connector.

Set the “HF ANT” item to 500 to use this connector (p. 31).

!1VHF/UHF ANTENNA CONNECTOR (p. 8) Connects an antenna to cover the frequency range over 30 MHz.

• Use a coaxial cable and type-N connector.
