Cleaning
Failure to comply with these instructions may invalidate any/all warranties.
Hand wash all surfaces of the bed with warm water and mild detergent. Dry thoroughly. DO NOT STEAM
CLEAN, PRESSURE WASH, HOSE OFF OR ULTRASONICALLY CLEAN. Using these methods of cleaning
is not recommended and may void this product’s warranty.
In general, when used in those concentrations recommended by the manufacturer, either phenolic type or
quaternary type disinfectants can be used. Iodophor type disinfectants are not recommended for use because staining may result. The following products have been tested and have been found not to have a harmful effect WHEN USED IN ACCORDANCE WITH MANUFACTURERS RECOMMENDED DILUTION.*

DILUTION
Quaternary Germicidal Disinfectants, used as directed, and/or Chlorine Bleach products, typically 5.25% So dium Hypochlorite in dilutions ranging between 1 part bleach to 100 parts water, and 2 parts bleach
to 100 parts water are not considered mild detergents. These products are corrosive in nature and
may cause damage to your stretcher if used improperly. If these types of products are used to clean
Stryker patient handling equipment, measures must be taken to insure the stretchers are rinsed with clean
water and thoroughly dried following cleaning. Failure to properly rinse and dry the stretchers will leave a corrosive residue on the surface of the stretcher, possibly causing premature corrosion of critical components.
NOTE
Failure to follow the above directions when using these types of cleaners may void this product’s warranty.
Do not use abrasive cleaners to clean the display enclosure for the optional scale system. Do not allow clean-
ing solutions or other fluids to pool on the display unit. Wipe dry all surfaces after spills or cleaning.
REMOVAL OF IODINE COMPOUNDS
This solution may be used to remove iodine stains from mattress cover surfaces.
1. Use a solution of 1−2 tablespoons Sodium Thiosulfate in a pint of warm water to clean the stained area.
Clean as soon as possible after staining occurs. If stains are not immediately removed, allow solution to
soak or stand on the surface.
2. Rinse surfaces which have been exposed to the solution in clear water before returning bed to service.

STATIC DISCHARGE PRECAUTIONS
The electronic circuits in the stretcher are completely protected from static electricity damage only while the
stretcher is asse m b led. It is extremely important that all service personnel always use adequate static protection when servicing the electronic systems of the stretcher. Whenever you are touching wires, you should
be using static protection.
Static Protection Equipment
The necessary equipment for proper static protection is:
S 1 static wrist strap; 3M part number 2214 or equivalent,
S 1 grounding plug; 3M part number 61038 or equivalent,
S 1 test lead with a banana plug on one end and an alligator clip on the other; Smith part number
N132B699 or equivalent.
CAUTION
All electronic service parts will be shipped in static shielding bags. Do not open the bags until you have completed steps 2 and 3 of the following procedure. Do not place unprotected circuit boards on the floor . All circuit
boards returned to Stryker should be shipped in the static shielding bags the new boards were shipped in.
Static Protection Procedure
1. Turn off the main power switch at the foot end of the stretcher and unplug the power cord from the wall
receptacle.
2. Insert the grounding plug into a properly grounded hospital grade wall receptacle. Plug the banana plug
of the test lead into the receptacle on the grounding plug. Connect the alligator clip on the other end of
the test lead to the ground chain of the stretcher.
3. Place the static control wrist strap on your wrist. Connect the alligator clip at the other end of the wrist strap
cord to the ground chain of the stretcher.

Displaying Individual Load Cell Outputs:
After entering diagnostics, press the lb / kg button to toggle up between the individual load cell readings.
15−45 lbs is a typical reading for an empty stretcher. Anything drastically outside that range indicates a problem with that load cell. Before replacing a load cell, verify the cable to the individual load cell is properly connected. A reading of 497.5 lbs indicates the load cell cable is disconnected or the load cell has been damaged.
If the system detects a defective load cell, the display will read Test then Err. Verify the load cell cable is proper-
ly connected. If it is, replace the load cell. When the load cell is functioning properly, the display will read
Test then Good. The scale will operate normally.

SCALE SYSTEM BATTERIES
NOTE
To avoid completely draining the batteries and having the optional scale system shut down, replace the batteries whenever only one of the charge indicator bars on the display is black.
1. Remove the two Phillips head screws holding the battery compartment cover on the display assembly.
2. Replace all four AA batteries, being sure to install the positive and negative poles as indicated on the
battery holder. Standard alkaline batteries are recommended. Do not mix old and new batteries or mix
different types of batteries. Properly dispose of the old batteries in accordance with local regulations.
3. Reinstall the screws and the cover.
If the display is flashing “Lo Batt”, the batteries are drained and the scale system is disabled. Replace the
batteries with four new AA batteries as described above.
