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: 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 4-1) of Power Panel.
Lead acid batteries last longer if not fully discharged.
Therefore, to obtain the longest life and capacity from
your STERIS 4085 General Surgical 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 (lighted green). If this is not always possible,
recharge batteries at the following times:
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.
• When table is first put into service.
• Every 15 days when table is in normal service; more
often if usage demands.
• Whenever HALF FILLED Battery ICON appears on
LCD Status Control Indicator.
• If table remains in extended storage for longer than
three months, batteries must be charged every three
months.
NOTE: If batteries do not charge, refer to S
ECTION
5,
T
ROUBLESHOOTING
, for possible causes and corrective
actions.
Recharge batteries as follows:
1. Connect ac power cord to table base and plug into
an appropriate ac receptacle.
2. Turn Main Power Switch to ON (lights green).
3. Allow a minimum of 12 hours for full battery
charge.
4. Verify green FILLED BATTERY ICON appears on
Hand Control and disconnect ac power.
NOTE: Depending on software version, if battery
voltage drops below either 19 V,
Plug Mains alarm
appears or below 23 V, Lo Batt alarm appears. Refer
to S
ECTION

, if either alarm
appears.
