Error Display Description/Countermeasure
Transmission error with remote control.
Change both the RL-SV1S and RC-50 to other channel.
If the error persists, check the transmission
environment and reduce wireless LAN and
other similar wireless transmissions as
much as possible.
More than 2 RL-SV1S devices are within the transmission range of the
RC-50, making transmission impossible. Change the channel for both
the RL-SV1S (1) and RC-50 used for the operation to another channel.
After recovering from the error, be sure to check the setting for each
function of the RL-SV1S.
Exceeding the adjustment range.
Turn the power of the RL-SV1S OFF, turn ON the power back again and
readjust.
This is an error with the RL-SV1S. Check the RL-SV1S display.
