Checking Wireless Lan Network Condition - Yamaha disklavier IV / Pro Series Maintenance Handbook

12. Checking wireless LAN network condition

In case of a strong wireless LAN network (Wi-fi) is exsisting around the disklavier, PRC100/TRC100
controller might have connection problem with the Disklavier. Open the network program from the
menu screen and check your LAN communication quality.
Wi-fi channel change by using I/O center dip switch function.
The Disklavier's default wi-fi channel is set to 5. It is possible that even though the network signal
is strong, the quality of the signal could be lower than 30%. If this is the case, change the channel
to avoid frequency conflicts. Try changing to channel 1 first. After changing, check the quality of
the signal again.
