3. Please switch the ammeter to Ω×1, and check control signals and
high-pressure signals impedance value. High-pressure signals are 100V
（White）and COM（Green）. If the there are more than one high-pressure
signals, please inspect these high-pressure signals as well.

☆ Usually, positive and negative (+/-) impedance values are high (above 500Ω)
unless there are any short-circuits. If that happens, use 1/2 troubleshooting
method to examine. Connect the cables to WMP-2100 after examining.
☆ After examining, turn on WMP-2100 and it will start auto-scanning. Make
sure all the decoders work properly then connect high-pressure signal lines
to a power amplifier.
☆ If more than two main consoles are connected, please make sure all the
connected apparatuses work properly. Next, inspect connection on
WMP-2100A according to
III. Linked control for two main consoles o n P. 14.
