IMPORTANTSAFETYINSTRUCTIONS
When using the Slide Scanner, basic safety precautions should always be followed including the
following:
•Readand understand all instructions before using.
•Position the cord so that it will not be tripped over, pulled, or contact hot or sharp surfaces.
•If an extension cord is necessary, a UL recognized grounded cord with a rating at least
equal to that of the slide scanner should be used. Extension cords rated for less amperage
may overheat. Connect the slide scanner to a grounded outlet.
•Always turn the host computerOFF and then the slide scannerOFF before unplugging.
•Always unplug the slide scanner from the electrical outlet before cleaning and servicing and
when not in use. Never pull the cord from the outlet. Grasp and pull the plug from the outlet
to disconnect.
•Do not disassemble the slide scanner, but take it to a qualified service person when service
or repair work is required. Incorrect assembly can cause electrical shock when the slide
scannerisusedsubsequently.

Power Cord Standard cord with ground.
Power Fuse Receptacle Thefusereceptaclecontainstwofuses:activeand
(SS35Only) spare.
The active fuse protects the slide scanner's electronics
from any sudden surges or overloads.
Note: If the active fuse fails (blows), always attempt to
find out the cause of the malfunction before
replacing the blown fuse with the provided spare.
Replace the spare fuse with a new one as
soon as possible.
Power Fuse Not user accessible. Located on power supply PC
(SS35PLUS) board.
SCSI ID Selector/Indicator The slide scanner's SCSI ID is preset at the factory
to 6.
SCSI ID position 7 is reserved for the SCSI adapter to
which the SCSI device(s) are connected.
Note: DO NOT change this value unless other SCSI
devices are attached to the slide scanner and
one of them is assigned to SCSI value 6.
If the preset SCSI value must be changed, refer
to the applicable slide scanner User's Guide for
detailed instructions on how to change the slide
scanner'sSCSIvalue.

SCSICable This cable (25-pin and 50-pin connector ends) connects
theslide scanner to the host computer.
Note: The 50-pin end of the SCSI cable connects to the
top SCSI receptacle. The 25-pin end of the SCSI
cable connects to the 25-pin SCSI port at the
rear of the host computer (Adaptec AT-to-SCSI
Host Adapter port for Windows version).
SCSITerminator SS35/SS35 ES:
SCSI terminator connects to the bottom receptacle.
SS35 PLUS:
SCSI terminator built in. To activate SCSI terminator,
set SCSI terminator switch to its ON position.
Notes: • To function properly, a SCSI chain must be
terminated at each end.
•The Adaptec AT-to-SCSI Host Adapter for
Windowsversion is internallyterminated,which
means that it is the first one of the required
terminators.
• If the slide scanner is theonly SCSI device to
be connected to the host computer, connect the
SCSI terminator to the bottom SCSI receptacle.
