[REC REMOTE] jack: Grounds when a signal is received and squelch opens. If a tape recorder has a control terminal, this jack can be used for record- ing control. (2 A/DC max.)

✔Convenient:

When an optional UT-102 VOICE SYNTHESIZER UNIT is installed, detected frequencies during scanning can be recorded. See pgs. 31, 32 for settings.

■Transceive function

Icom CI-V transceivers or receivers can be connect- ed via the [REMOTE] jack. The frequency and mode become the same* when either radio is changed.

*When a set frequency is out-of-range for one of the con- nected transceivers or receivers, the connected radio’s frequency/mode does not change.

Connect to [REMOTE] jack

• Be sure the “CIV TRAN” item is turned ON in initial set mode (p. 32).

■Connecting to a PC

The IC-R8500 can connect directly to a personal computer providing control of multiple functions such as instant frequency/name programming using appropriate software. See pgs. 35, 36 for the control command table.
