Remote Site Setup
The Remote K3 must have firmware version 4.48 or later installed.
1. Apply power to the K3 and confirm that it has firmware version 4.48 or later installed. If not, update the
firmware as described in the K3 Owner’s manual.
2. Set the K3 for rear panel mic input and no bias (see the K3 Owner’s manual for details), regardless of
the type of mic used. The RRC-1258 units automatically supply bias.
3. Cable the remote site K3 to the RRC-1258 unit as shown in Figure 12 using the RRMTCBL cable set.
You must use the RRC-1258 unit that does not have the CW knob on the front panel.
