• Read this owner’s manual before assembly or operation.
• Do not allow children to move the lectern.
• Proceed slowly and carefully when moving the lectern.
• For indoor use only. Do not install or store the lectern where it will be exposed
to moisture.
• Do not block the ventilation openings.
• Avoid uneven loading of the equipment into the lectern. Uneven weight
distribution could cause the lectern to tip when the lectern is moving.
• Do not allow anyone to sit, stand, or climb on the lectern.
• Use a damp, soft-cloth, or sponge, with mild soap or detergent solution to clean
dirty surfaces. Do not use harsh solvents or abrasives.
• This lectern is intended for institutional use. It does not have any user-
serviceable parts or user-maintenance requirements. If servicing is necessary,
please contact Spectrum Industries for assistance.
Electrical Safety:
• Do not plug the power cord into an extension cord.
• Inspect power cords for damage before each use. Do not use power cords
that are damaged.
• Unplug power cord from electrical outlet by gripping the cord. Do not unplug
the power cord by pulling only on the cord.
• Do not step on, drive over, drag, or place objects on the power cord.
• For added safety, plug the lectern into a grounded outlet controlled by a GFI
(Ground Fault Interrupter) circuit breaker.
• Electrical devices are not toys. Children are often unaware of the hazards
associated with electrical devices. This lectern must always be used by
adults or with adult supervision.
Warning - Relocating audio and/or video equipment to furniture not speci cally
designed to support audio and/or video equipment may result in death or
serious injury due to the furnishing collapsing or over turning onto a child.
Warning - Death or serious injury may occur when children climb on audio
and/or video equipment furniture. A remote control or toys placed on the
furnishing may encourage a child to climb on the furnishing and as a result the
furnishing may tip over on to the child.

should be reviewed by Spectrum to ensure clear-
ance of brackets, keyboard slides, or other objects
under the worksurface.
