modulated to 60% of system deviation, at 1kHz AF.
Adjust the RV2 for a line output level of -10dBm.
Setting the Line
Input Level (RV3)
Apply a line input signal of -10dBm and key the transmitter.
■ For a two-wire configuration, apply the line input signal to pins 14 and
15 on SK1.

10 on SK1.
Adjust RV3 until 60% of system deviation at 1kHz is achieved.
2.3 Installing the Line-Interface Board
Note The line-interface board link options must be set before the board
