2. Inspect condition of AC adapter cord and prongs, replace if needed.
CLEANING
Proper care and cleaning is essential to ensure a long life of accurate and effective operation. Disconnect the scale from the AC power source
1. Clean all external surfaces with a clean damp cloth or tissue. Mild soap and water solution may be used. Dry with a clean soft cloth.
2. Do not immerse the scale into cleaning or other liquid solution.
3. Do not use Isopropyl Alcohol or other solutions to clean the display surface.

.TROUBLESHOOTING.

Refer to the following instructions to check and correct any failure before contacting service personnel.
SYMPTON
Scale does not turn on
Questionable weight or the
scale does not zero
The display shows "OVER"
The display shows "LO Bat"
message
ERROR LIST
ERROR
NO.
Err 1 Mathematical mistake; division by zero. Cannot
calculate calibration factor
Err 2 Weight loaded too low. Cannot calibrate
Err 3 Unstable weight. Cannot calibrate
Err 5 Calibration disabled
Err 6 High saturation state (high A/D)
Err 7 Low saturation state (low A/D)
POSSIBLE CAUSE
1. Dead Battery
2. Faulty electrical outlet
3. Bad Power Supply (Check LED
light at back of display module to
determine if adapter cord is
working)
1. External object interfering with
the scale
2. The display did not show '000.00
before weighing
3. Scale is not place on a level ˛floor
4. Scale is out of calibration
The load on the scale exceeds the capacity
(600lbs)
The batteries are dead
DEFINITION
CORRECTIVE ACTION
1. Replace batteries
2. Use a different outlet
3. Replace adapter
1. Remove interfering object
from the scale
2. Ask the patient to get off the
scale, zero the scale and begin
weighing process again
3. Place the scale on a level floor
and begin weighing process
again
4. Check weight with known
weight value
Remove the excess weight and use the
scale according to its limits
Replace batteries according to instructions
CHECK/REPLACE
Will show when trying to calibrate with no calibration
weight
While in calibration procedure add more weight in
load mode
Check the load cells mechanical surroundings and see
nothing touches them and the cables are well
connected
Toggle the calibration switch to enable
The load cell is not connected correctly. Check the
connection, cables, and mechanical connection. If
the problem persists, replace the set of load cells
