056404-443 Operator Manual Routine Maintenance
Batteries require recharging on a periodic basis depending on frequency of table usage. Low or discharged
battery conditions are indicated by HALF FILLED or EMPTY BATTERY icon on the Hand Control and some or all
green diode bars on Power Panel LED Display are OFF.
NOTE: Maximum life expectancy for a battery that has a history of proper care and charging is 4 years. More
frequent battery replacement will be required if charging recommendations are not followed.
NOTE: Fully charged batteries enable between 100 and 150 procedures (approximately three weeks) without
recharging. Note the charge/discharge ICON on the LED Display (see Figure 6-1) of Power Panel.
NOTE: When two green diode bars on Power Panel LED Display are OFF, batteries are half charged. This level of
power enables normal table operation without damaging the batteries. However, when the last green diode bar is
OFF, batteries must be recharged without further delay or battery damage occurs. If all diodes are OFF, batteries
are completely drained and the table can only operate on main facility power.
Lead acid batteries last longer if they are not permitted to fully discharge. Therefore, to obtain the longest life and
capacity from the table batteries, always connect ac power cord to table base and plug into an appropriate ac
receptacle as often as possible, and as long as possible, with the Main Power Switch set to ON. If this is not
always possible, recharge batteries at the following times:
• Every 15 days when the table is in normal service; more often if usage demands.
• Whenever HALF FILLED BATTERY icon appears on LCD Status Control Indicator.
• If the table remains in extended storage for longer than three months; batteries must be charged every
three months.
NOTE: If the sealed lead-acid gel electrolyte-type batteries do not charge, check for the following:
1) Battery fuse is blown - replace the fuse (refer to Section 4.5, Installing Battery Fuse (F8)).
2) Ac power cord is defective - replace if necessary.
3) Main Power Switch is OFF (not illuminated).
4) Charger Circuit is not operating.

WARNING – PERSONAL INJURY AND/OR EQUIPMENT DAMAGE HAZARD: Repairs and
adjustments to this equipment must be made only by STERIS or STERIS-trained service
personnel. Maintenance performed by unqualified personnel or installation of unauthorized parts
could cause personal injury, result in improper equipment performance, invalidate the warranty, or
result in costly damage. Contact STERIS regarding service options.
WARNING – TRIPPING HAZARD: Route the power cord to the receptacle to minimize being tripped
over by personnel in the area.
