PROTECTION CICUIT
• If the power auto shuts off a few seconds after turn
on, most likely it is caused by the power protection
circuit. We describe the protection circuit on models
RX-D201/202. It is similar to other RX-D... series
models and can be used as a reference for
troubleshooting.
• There are 7 protection input pins (only 5 pins used in
these 4 models) on CPU IC501; any of them could
cause the protection circuit to be triggered and shut
down the power. The marked voltages are +5~10%
tolerance.
• The underline marked voltages can be measured in
power standby mode; (e.g. 2.01v, 4.83v ...) but have
to be checked again once power is on.
