Battery charge status is shown via a LED on the hand pendant labeled "Battery Status".
If illuminated green = OK.
If illuminated red = charge.
If a recharge is required, charge a minimum of 3 hours. A full charge should be available after 18 hours.
To charge the batteries simply plug the power cord into an appropriate “hospital grade” outlet and turn the
on/off power switch “ON”. It is important to plug in the table as soon as possible after the battery status
LED is illuminated red. Life of the battery can be shortened if the table remains unplugged and turned on
for extended period of time. While in storage it is desirable that the table be plugged in and the power
switch turned on so that the batteries remain charged. If this is not possible, the batteries must be
charged for at least three hours a week. This can be accomplished when using the table under AC power
since the system batteries are automatically charged while the table is plugged in and turned on.
Both batteries should be replaced every five (5) years or when they fail to hold a charge. See Section 7.4
or User Guide for disposal instructions.

7.0 MAINTENANCE
7.1 Cleaning and Disinfection
NOTE: Never pour any liquid directly onto the table. Never subject the 6850 Table to an equipment
washing machine.
USE OF IODOPHORS WILL CAUSE STAINING.
Table Exterior:
1. Exterior surface should be regularly wiped clean with a mild detergent solution and wiped dry with a
soft lint-free cloth.
2. Care should be taken to avoid exposing the table to excessive moisture. Flooding, fogging or steam
cleaning is not recommended.
3. Blood or other fluids, etc., if allowed to remain on the table for a long period of time, will require
special cleaning to remove. A 5% acetic acid solution or white vinegar and water solution is
especially good for this purpose.
4. Cleaning with a good commercial cleaning compound, such as Stainless Steel Magic or Acme White
Finish, and then buffing the surface by hand can correct staining and discoloration of plated or
stainless steel surfaces only.
5. To disinfect exterior surfaces use a quaternary ammonium or similar type disinfectant compound
according to manufacturer's directions for use. Wipe dry with a soft lint-free cloth.
NOTE: Failure to thoroughly dry surface after cleaning and disinfecting may result in rust.
Casters:
Casters should be cleaned and disinfected in the same manner as table exterior. Access to the casters is
achieved by removing the sheet metal enclosures at each end of the table base.
NOTE: Before removing any sheet metal covers the table must be turned off and unplugged. Dangerous
high voltage may be present in the circuitry under the covers. Only trained technicians should perform this
task.
