2. Processing when test mode starts
2-1. Manual test mode
If the Test L1/L2 port (IC501
!ª
pin) is high, for L1 commu-
nications, L1 is connected to the audio path and if it is low
for L2 communications, L2 is connected to the audio path.
Set the channel to 1 (see the channel setting table) and set
TX to On.
2-2. Machine test mode
If the Test L1/L2 port (IC501
!ª
pin) is high, for L1 commu-
nications, L1 is connected to the audio path and if it is low
for L2 communications, L2 is connected to the audio path.
Set the channel according to the port logic (see the channel
setting table) and set TX to On.
