Battery Replacement
* The SH-101 adopts AC and Battery
Powered System.
De not turn the Power switch on before
connecting the AC Adaptor to the SH-
101. Connecting the AC adaptor while
the Power is on may cause troubles.

set of new ones when the Battery Check
indicator flashes. If you fail to replace
the batteries within one hour, the
SH-101 will stop operating properly.
* The batteries last for approximately 10
hours when using only battery power.
{it varies depending on the type of the
batteries, how often the unit is used,
etc.}
. Turn the Power switch off. If using an
AC adaptor, disconnect the power cord.
. Remove the cover from the battery
housing and take out the batteries.
3. Replace with new batteries.
* Make sure that the polarity of the bat-
tery is correct.
Place the three batteries in the front
part of the housing. (A). In this case,
place to the sides, then in the middle.
if using only three batteries for retain-
ing the sequencer memory, put the
batteries in the back part of the hous-
ing. (B)-
. Put the cover back to the housing.
If the batteries are changed within
one minute, the memory will hold the
sequencer data.
IMPORTANT NOTES
* When the SH-101 is not to be used for
long periods, remove the batteries to
prevent leakage.

* Be sure to keep the batteries in the
housing even when using an AC adaptor.
Then, if the AC adaptor is disconnected,
operation immediately changes to bat-
tery, allowing the sequencer's data to be
retained.
When using an AC adaptor, use only the
BOSS AC Adaptor PSA-120, 220 or 240
depending on your country's voltage
system.
If you wish to protect the sequencer
aata after the Power switch is turned
off, use 3 batteries.
When operating the SH-101 only by bat:
teries, use 6 batteries. The sequencer
data will be retained.
the LFO/CLK rate, therefore, if the rate
is set too slow or too fast, you may fail
to notice the flashing.
If using the batteries just for a back-up
circuit to protect the memories, battery
replacement is required just once 3 year.
When the SH-101 is operating by bat-
tery power, be sure to turn the Power
switch off when it is not in use (to pre-
vent unnecessary consumption of the
batteries.)
