Introduction
Overview
Spacelabs Healthcare designs and manufacturers its products under
good manufacturing practices and in compliance with all applicable
regulatory requirements. To make sure that the product operates
correctly in accordance with these guidelines, trained technicians
using Spacelabs Healthcare authorized replacement parts maintain
this product.
The expected service life of the monitor is seven years from the date
of installation, but its service life can be extended. Many of the
monitor parts are replaceable. Calibration is not required, but
routine safety checks are required. Install a functional battery in the
unit for normal operation. Check the battery periodically and replace
it when necessary.
The qube™ monitor has a 26.2 cm (12.1 inches) LCD display with 1024
x 768 resolution. It has an intuitive user interface and a stylish,
compact design. The monitor includes a single module slot and
supports up to three Flexports® and four USB devices (a mouse,
keyboard, barcode scanner, etc.). Available options include an
integrated recorder and 802.11a/b/g wireless. Dual-battery slots
allow for its use as a transport monitor, as well as at the bedside.

91390 QUBE INTRODUCTION
External AC Power Supply
The external AC supply that powers the monitor meets worldwide
safety and EMC requirements. The external AC supply provides
20 VDC. The external AC supply provides 20 VDC at 4.5 Amps. The
external power supply (an AC/DC converter) has a 6pin rectangular
connector (P/N 119-0552-00).
Batteries
The option A monitor accommodates the use of two removable
internal batteries. At least one battery must be installed for normal
operation.
The option B monitor has two fixed (non-removable) batteries. The
option C monitor has one fixed (non-removable) battery.
For more information, refer to Batteries and Recharging Batteries on
page 1-14.
Display
LCD Display
For options A and B, the LCD display assembly provides multicolor
visual alarm notification based on the severity of the alarm. The
software controls the operation of the alarm lights. There is a red
light for high priority, a yellow light for medium priority, and a cyan
light for low priority and technical alarms.
The alarm lights are visible directly above the display screen on
options A and B, and on the rear of the monitor above the handle on
option A.
Video Subsystem
The primary display is a 12.1-inch color TFT LCD. The video interface
is 24-bit Flat Panel Display Link (FPD-Link) using LVDS.
The display has an LED backlight supplied with 12-volt power. A
PWM control signal controls the brightness of the LED backlight.
The power supply microcontroller generates the PWM control signal
under the direction of the host application.
The secondary display is an external monitor compatible with
standard Digital Visual Interface (DVI) signaling. The interface is
DVI-D which supports digital-only, single-link.
The secondary display has the same image and resolution as the
primary display.

• The battery provides power to the monitor when it is
separated from the AC power.
• Batteries charge when the monitor is connected to the AC
power.
• The monitor auto-switches to battery operation when
separated from the AC power.
• Remove batteries if the monitor is not likely to be used for
some time.
• Remove batteries from the monitor before storage or
shipment.

Energy Saving Mode (Battery)
The qube has an energy saving mode. Energy saving mode lets the
monitor dim after 30 seconds of no interaction. If you enable this
mode, do not touch the monitor for 30 seconds to see it dim. The
monitor does not dim if you use a mouse with the monitor or an
alarm event occurs. Refer to the XPREZZON and qube System
Administration Manual (P/N 070-2380-xx) for more details.
Signal Strength Indicator
Monitors equipped with option X (an embedded 802.11a/b/g
transceiver) are labeled at the factory. A separate label is provided
with the option X kit for field installation (Refer to Figure 1-6).

91390 QUBE INTRODUCTION
Monitors with wireless network communication show a wireless
signal strength indicator while they communicate over the wireless
network. To use the wireless feature, disconnect the wired network
connector. Not all qube monitors include the wireless option.
The wireless signal strength shows between the Admit Patient
button and alarm buttons. The signal strength shows a green
antenna with vertical bars on a black background. The number of
bars show the strength level. One bar is low strength. The strongest
signal is five bars. The signal changes to yellow when the network
connection is lost. For more information, refer to the XPREZZON and
qube System Administration Manual (P/N 070-2380-xx).

Batteries and Recharging Batteries
For option A, the monitor uses smart batteries, and at least one
battery must be installed for normal operations. If it uses two fully
charged batteries in a standard configuration, the monitor operates
up to eight (8) hours. With one fully-charged battery in a standard
configuration, the monitor operates up to four (4) hours.
The battery icon shows if the batteries are inserted. This icon shows
how much charge the batteries have. The icon updates every six
seconds and is to the left of the audio icon on the lower-right
section of the monitor. Refer to Table 1-5 on page 1-15.
Charge temperature limits are ≤80% RH.
The battery must be capable of continuous charge at 12.6 V. To
charge the battery, only use a dedicated level II or level III smart
battery charger. When you use a level II or level III smart battery
charger, the battery requests the appropriate charging voltage and
current.
The FULLY_CHARGED bit in the Battery Status is set when the
charging current tapers down to under 240 µA, while charging at
12.6 V.
Notes:
• The battery life greatly depends on usage, age, and the
environment. The battery operating life decreases over time.
Caution:
Signal strength and radio system congestion can contribute to waveform
gaps over the wireless network. Should this be a persistent issue, consult
with a Spacelabs Healthcare field service representative.
