MACHINE TEST MODE
Set the Test Mode:
1.When power on reset is applied while a “H” (high) is input the TEST SW (TP43) terminal (IC501 $º pin), the RING (Level
H, 500 msec.) sounds.
2.Following that, at timing in which the TEST SW terminal has “H” (high) input, there is output of “L” (low) by the CH (channel) setting control terminal. Then there is PLL setting to the CH which was read to with the CH setting terminal according to that “L” (low) output.
3.Set the TX setting to TX OFF.
4.The channel is set by voice not by data.
5.Use port inputs to set output from LED terminals.
Release the Test Mode:
