CHAPTER Safety
Please read this information before servicing the SiteStand.
A WARNING describes precautions necessary to prevent injury or loss of life.
A CAUTION describes precautions necessary to protect the products.
2.1 Electrical Safety
For maximum safety observe the following warnings and cautions:
WARNINGS:
Shock hazards exist if the AC power adapter is not properly grounded. Grounding
reliability can only be achieved when equipment is connected to a receptacle marked
“Hospital Only,”“Hospital Grade,”or the equivalent. The grounding wire must not
be removed or defeated.
To avoid the risk of electrical shock and fire hazard, inspect the AC power adapter
cord and plug on a regular basis. Ensure they are not damaged.
Connection of peripherals not recommended by SonoSite could result in electrical
shock. Avoid electrical shock hazards by using peripherals and accessory cables
recommended by SonoSite.
To avoid the risk of electrical shock, use commercial grade peripherals
recommended by SonoSite on battery power only. Do not connect these product to
AC mains power when using the system to scan or diagnose a patient/subject. Call
SonoSite technical support or your local representative for a list of the commercial
grade peripherals available from or recommended by SonoSite.
CAUTIONS:
Electrostatic discharge (ESD), or static shock, is a naturally occurring phenomenon.
ESD is common in conditions of low humidity, which can be caused by heating or

2: Safety
6SiteStand Service Manual
air conditioning. Static shock is a discharge of the electrical energy from a charged
body to a lesser or non-charged body. The degree of discharge can be significant
enough to cause damage to a transducer or an ultrasound system. The following
precautions can help reduce ESD: anti-static spray on carpets, anti-static spray on
linoleum, and anti-static mats.
For labeling symbols used with the SiteStand, please refer to the SonoSite 180 or
SonoHeart User Guide. For information about the flat panel display, please refer to
the Operating Instructions for the Series DV-3000 Colour LCD Rugged Monitor.
2.1.1 Equipment Protection
To protect your ultrasound system, transducer, and accessories, follow these
precautions.
CAUTIONS:
Excessive bending or twisting of cables can cause a failure or intermittent operation.
Improper cleaning or disinfecting of any part of the system can cause permanent
damage.
Do not handle PCBs without proper static protection. Damage to components may
result from improper handling.
2.1.2 Electrical Safety Testing
*Note: 300uA is the limit for 120V stands only!

altering this order to provide repairs to various parts of the SiteStand.
Table 3.1 SiteStand Troubleshooting
OBSERVATION POSSIBLE CAUSE CORRECTIVE ACTION
The system battery doesn’t
charge in the SiteStand. If the charge function of the system is acceptable, the
possible causes are:
•the power supply has
failed or become
disconnected
•the dock PCBA located
in the sleeve assembly
has failed
•the docking connectors
on the sleeve assembly
are broken or bent.
Verify the SiteStand is at
fault by attempting to charge
the battery with the power
supply connected directly to
the system. If it does not
charge, refer to the SonoSite
180 Service Manual for
troubleshooting.
There is no video from the
SiteStand video out
connection.
The SiteStand docking
PCBA has failed.
The docking connections or
the sleeve assembly have
been broken.

Assembly and the Docking
PCBA on page 9.
There is no AC power from
the SiteStand power
connection.
The SiteStand fuse has
failed. See Replacing the SiteStand Fuse on page 10.
There is no remote printer
control to the printer on the
SiteStand.
The printer remote control
cable has failed or is not
attached correctly.
Replace the printer remote
cable (P00762).
There is no output from the
RS-232 communication port. The SiteStand docking PCBA has failed.
The docking connections on
the sleeve assembly are
broken or bent.
See Replacing the Sleeve
Assembly and the Docking
PCBA on page 9.
The sleeve assembly does
not raise or lower. The foot pedal is damaged.
The gas spring is loose or
damaged.
The foot pedal has fallen off.
See Replacing the Foot
Pedal on page 9.
The SiteStand does not roll
easily or in a straight line. A castor(s) is broken or bent.
The SiteStand base is
damaged.
Replace the failed part.

Disassembling the SiteStand
SiteStand Service Manual 9
3.3.1 Required Tools
•#1 Phillips screwdriver
•Allen wrench set (5/32-inch, 1/8-inch, and 5/64-inch)
•Slotted screwdriver
•Open end wrench (11/16-inch)
•Round punch (1/4-inch)
3.3.2 Replacing the Sleeve Assembly and the Docking
PCBA
1. Tilt the sleeve assembly to its most upright position.
2. Use a #1 Philips screwdriver to remove the six screws from the metal base of the
sleeve assembly.
3. Turn the sleeve assembly over and remove the two screws holding the cable
connector to the sleeve assembly.
4. Unplug the connectors and set the sleeve assembly aside.
5. Remove the five Phillips screws attaching the PCBA to the sleeve assembly.
3.3.3 Replacing the Power Supply
1. Lay the SiteStand on a bench with the base facing you.
2. Use an Allen wrench to remove the four 5/32-inch Allen screws holding the
base.
3. Remove the base and set it aside.
4. Use an Allen wrench to remove to remove the six 5/32-inch Allen screws and
the 11/16-inch nut on the gas spring securing the subplate.

6. The power supply is visible in the forward section of the SiteStand and is
secured by Velcro. Pull the power supply loose and disconnect the connectors.
7. To reassemble the SiteStand follow steps 1 through 6 in reverse order.
3.3.4 Replacing the Foot Pedal
Earlier versions of the SiteStand use a pin to hold the foot pedal in place. If the pin
has become loose, you should replace the foot pedal with foot pedal repair kit
(P01321).
1. Remove the pin using any round punch.
2. Install the foot pedal using the shoulder bolt in place of the pin.
