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
µ
A, 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.
