When Not In Use For A Prolonged Period - Roland SJ-740 User Manual

3-8 When Not in Use for a Prolonged Period

Even when not in use, keep the machine in an environment where the temperature is 5 to 40 ˚C (41 to 104 ˚F) and the humidity
is 20 to 80 % (no condensation). In particular, be careful to make sure not to expose the machine to high temperatures of 40 ˚C
(104 ˚F) or more.
When the machine is out of use for an extended period, then once a month, switch on the power and perform cleaning.
When the machine's main power switch is left on, a warning beep sounds about once a month to remind you to perform
cleaning. We recommend switching off only the sub power and leaving the main power on even when the machine is out
of use for an extended period.
