Introduction
Overview
Spacelabs Medical’s products are designed and manufactured under good manufacturing practices
and in compliance with all applicable regulatory requirements. To ensure proper operation in
accordance with these guidelines, this product must be maintained by trained technicians using
Spacelabs Medical authorized replacement parts.
This manual applies to the 90385 Universal Clinical Workstation (UCW®) and the 90387 Ultraview®
1700 monitors. The 90385 UCW monitor is a fully Ultraview-compatible bedside or central monitor. It
features a 15-inch color display and an infrared touchscreen.
The 90387 Ultraview 1700 monitor combines the module-mounting capability of the 90491 module
housing, with the processing and display capabilities of the 90385 UCW. The right side of the
chassis is used to house the CPU and I/O PCBAs, while the left side provides two slots for module
plug-in. The Ultraview 1700 is capable of driving an external speaker (either amplified or
unamplified) or may stand alone, using the internal speaker. The result is a product that provides the
same Ultraview Care Network™capabilities as the UCW, but adds plug-in support for two modules
in a single, compact unit, with a separate display. The Ultraview 1700 is primarily intended to
function as a compact, two-module bedside or central monitor.
!• This service manual is intended for use with 90385 monitors, serial numbers
385-3xxx and higher, and 90387 monitors, serial numbers 387-1xxx and higher.

Example:
A 90385-XFQ (where “X” represents the language designator) is an UCW equipped with:
• Q = Data Shuttle option
• F = Four waveform zones
Accessory devices supported by the UCW/1700 are as follows:
Modules — Supports all existing Ultraview modules except 90425, 90428, 90432, and 90410. Use
of modules in conjunction with the UCW requires a module housing(s) and DC power supply(s);
whereas, the Ultraview 1700 provides plug-in support for either two single-height modules or one
double-height module. Additional modules are supported by means of external module housings.
Flexport®system interfaces — Supports the use of all existing Spacelabs Medical Flexport
interfaces. Refer to Setup on page 2-1 for installation requirements.
Repeater Displays — Up to two repeater displays may be connected. The repeater displays serve
only to duplicate the information shown on the Ultraview monitor and does not accept user input.
Repeater displays may be located up to 100 feet from the Ultraview monitor.
Touchscreen — The Ultraview 1700 supports the ELO Touch brand touchscreens. The UCW uses
an integral infrared touchscreen.
Mouse — Supports the use of a PS/2-style mouse.
Keyboard — Supports the use of a PS/2-style keyboard.
Nurse Alert — Supports the use of a Spacelabs Medical nurse alert device. This device provides an
external indication that one of the parameters being monitored is in an alarm condition.

Setup

Pre-Installation Testing
Before mounting the equipment, it is recommended that you first verify its operation as
follows:
1. Power ON the unit and let the power-on diagnostics run.
2. Look in the upper-left corner of the display for any diagnostic failures or other system errors.
The monitor will start up normally if no unacceptable diagnostic errors occur. Refer to
Troubleshooting on page 5-1 for more information on the diagnostics features if the monitor
does not start up normally.
3. Insert at least one parameter module for testing purposes.
4. Refer to Preventive Maintenance (PM) Procedures on page 4-3 and complete those
procedures.
Mounting
The monitor can be mounted in one of three ways:
Wall Mount — The unit is attached to an adjustable mounting arm that projects out from a wall
track. This mounting scheme is suitable for a bedside configuration.
Pedestal Mount — The unit is securely attached to a flat surface, such as a shelf or an
operating room cart.
Roll Stand — The unit can be easily rolled from one location to another.
The 90387 can also be operated unmounted in a free-standing, table-top configuration, or it can be
console-mounted.
For installation requirements of the module housing(s), refer to the Module Housings and Power
Supplies Service Manual (P/N 070-0680-xx, located on CD-ROM 084-0700-xx).
Base Tension Adjustment (90385)
The 90385 monitor’s base can be adjusted to increase or decrease the tension that allows tilting of
the monitor screen. Tension is factory-adjusted for optimum performance and further adjustment is
usually not necessary. If adjustment is necessary, turn the base screw clockwise (refer to
Figure 2-1) to increase base tension or counter clockwise to decrease tension. Set the tension
loosely enough to allow normal viewer adjustments, yet tightly enough to hold the adjusted position.

!• If necessary, base adjustment must be done prior to installing the monitor onto a
mount.
• Not all monitors will have the base tension adjustment described here.
!• Specific wall requirements for the installation of wall mounts are not covered in
this manual and are the responsibility of each hospital. Refer to the Module
Housings and Power Supplies Service Manual (P/N 070-0680-xx, located on
CD-ROM 084-0700-xx) for detailed instructions.

Setup
2-5
The wall mounting hardware consists of:
Wall Track — The wall track is mounted vertically on the wall with the mounting arm installed in
the track. The mounting arm can be slid up and down in the wall track to the desired height. Wall
tracks are available in multiple lengths.
Wall Track End Caps — The wall track end caps are installed on the top and bottom of the wall
track to give the track a finished appearance and to prevent the equipment from sliding off the
end of the mounting track.
Mounting Arm — The mounting arm projects horizontally out from the wall track and holds the
display assembly and module housings. Two types of arms are available: one for a monitor-only
installation; the other for installation of the monitor and module housing(s).
Mounting Screws — Mounting screws are provided to install the end caps and to secure the
mounting arm at the desired vertical position.
Mounting Considerations
Power supply should be placed no closer than three inches (7.62 cm) to the remote housings to
allow sufficient air flow. Install a minimum of four AC outlets.
Pedestal Mounting (90385)
To attach the pedestal mount to the display assembly refer to Figure 2-3.
1. Verify that the pedestal’s six rubber feet and four retaining studs with retaining rings have
not been dislodged during shipping.
2. Carefully place the display on its side. A cushion should be used under the display to avoid
scratching the display case.
3. Rotate the display’s round base (if necessary) so that its tick mark points toward the front of
the unit.
4. Line up the four retaining studs on the pedestal with the four holes in the display’s round
base.
5. Push the pedestal onto the round base and secure it by turning each of the four retaining
studs 90 degrees clockwise with a straight blade screwdriver. The studs will lock in place
and can no longer be turned.
6. Carefully return the display to its normal upright position.
!• The monitor, monitor wall plate, and AC outlet must be located on the same side
of the patient bed. The power cord has a standard length of 10 feet (3.05 m).

Console Mounting (90387)
The physical layout and other console characteristics depend on the requirements of the hospital or
other institution. It is the responsibility of the institution to define its specific console needs and to
design and construct the console according to its specifications.
For this reason, Spacelabs Medical does not supply a pre-fabricated console assembly. Instead, this
section provides the information necessary to create a custom console design. In designing the
console, the following considerations must be kept in mind.
• Access
The rear of the console must be designed to allow for easy access. The dimensions of the rear
access door must allow the 90387 and display monitor to be easily installed and removed.
• Cooling
The console cabinet must be designed to allow sufficient air flow for natural convection.
If the console cabinet is enclosed, one of two cooling methods can be used:
Central Air Conditioning — The console can be connected directly to an air conditioning
cooling duct. The maximum ambient air temperature should be limited to approximately
32° C, and vented from the console at the highest exit.
!• The 90387 does not contain a fan.
