System Maintenance and Repair:
Handling Considerations
• The Guideline 4000 LP+ is intended to be used in a standard operating room environment.
• Store the Guideline 4000 LP+ at room temperatures between 0°C (32°F) and 40°C (104°F).
• Neither the Guideline 4000 LP+ nor its components are designed for sterilization.
• Do not drop the Guideline 4000 LP+ or its components.
• Only transport the Guideline 4000 LP+ inside of its shipping container, with included foam insulation.
Maintenance
• The Guideline 4000 LP+ must be inspected and recalibrated each year by an FHC authorized representative. Contact FHC for
more information on Service Agreements and Preventive Maintenance Programs.
• The Guideline 4000 LP+ and its components may be cleaned by wiping a dry rag lightly over all surfaces. If necessary, a slightly
damp cloth moistened with a standard hospital disinfectant may be used.
Repair
• All FHC products are unconditionally guaranteed against defects in workmanship for one year from the date of shipment,
provided they have been exposed to normal and proper use.
• Should service or repair be required, please contact FHC at 1-800-326-2905 (US & Canada) or +1-207-666-8190 for return
instructions.
End-of-Life System Disposal
Return the Guideline 4000 LP+ to FHC for proper end-of-life disposal. Please contact an FHC factory authorized
representative to arrange a return.
