Ensure that the following transportation instructions
are adhered to before moving the 1602 table:
a. Remove the power cord.
b. Place the main power switch in the OFF position.
c. Tighten all handles and knobs.
Ensure that the following packaging guidelines are
adhered to when shipping the 1602 table:
• The 1602 table must be shipped in a
suitable container and sealed from the outside
atmosphere.
• The shipping container must employ
appropriate reinforcement to prevent table
vibration or movement during shipment.

two (2) 12 volt, sealed, lead acid batteries available
only through SKYTRON.
Certain accessories, such as the Uro-Drain Tray,
Arm boards, and X-Ray top, can be damaged when
changing the position of the table top sections.
Alwayslookrsttoseeifadesiredmovementis
going to interfere with any accessories in use.
The operator has the ultimate responsibility of
preventing damage to the table and surrounding
equipmentorpossibleinjurytothepatientorsta󰀨.
The operator must ensure proper positioning is
maintained to prevent compromising respiration,
nerve pathways, or circulation.
In general, use common sense to dictate when
there is a potential hazard.
1-1. Special User Attention

in close proximity to the table, ensure that these
devices comply with electromagnetic compatibility
medical standards.
The extreme positioning capabilities of the 1602
table requires special attention for possible
interference points when using multiple function
positioning. As with the operation of any surgical
table, a certain amount of care should be exercised
to position the patient safely. Although the thick
pads and sheets substantially protect the patient,
pinch points, located at the joints of the top section,
should always be considered. BE SURETHATTHE
ARMS, HANDS,AND FINGERS OF THE PATIENT
AND THOSE OF THE OPERATING ROOM
PERSONNEL ARE CLEAR OF ALL MOVING
PARTS BEFORE MOVING THE TABLE. Refer to

3-8. Charging the Batteries
CAUTION
Batteries must be properly maintained
to ensure table operation in the event
of an AC power supply failure.
Batteries should be charged:
• When the table is placed into initial service
• As indicated by the pendant battery indicator light
• Every week under normal service conditions
Three (3) green LEDs, on the battery indicator are
turned on according to the charge state.
The following table shows the battery charge level
as indicated by the lighted bars.
Indicator Status Percent Charge
75% ~ 100% (Fully charged)
30% ~ 75% (Charged)
Less than 30% (Charged)
Needs recharging immediately
NOTICE
The charging system operates ONLY
when the table is inAC operation mode.
The table can be operated onAC power
while the batteries are being charged.
To recharge the batteries, make sure the power
cord is connected to the table and plugged into a
AC wall outlet, and the base power switch is ON.
The batteries require 8 to 12 hours of continuous
recharging to reach a full charge. The charging
system will automatically reduce input amperage
as capacity reaches 90% to avoid over charging.
It is recommended to charge the batteries at the end
of each week to establish a normal routine. The
batteries last longer if they are not permitted to fully
discharge. The batteries require no maintenance,
and should provide an approximate normal life of
4 years under a proper charging program.

WARNING
Ensure brakes are properly set prior
to patient transfer. DO NOT UNLOCK
BRAKES when a patient is on the
table. An uneven patient weight load
may cause instability.
DO NOT use the table to transport a
patient or heavy objects. There is a
risk of injury to the patient and sta󰀨
if the patient should fall or objects
dislodge during transport.
CAUTION
If circumstances demand table
brakes to be unlocked:
Patient must be centered and evenly
distributedonthetabletop(i.e.,supine
or prone position) with the table
lowered to its lowest height position.
Maximum patient weight should not
exceed 500 pounds (227 kg).
Patient's head must be on the head
section. Head section must be
attached in its normal orientation to
