WARNING Short range radio connections are subject to interruption due to interference from other radio sources
in the vicinity, including microwaves, bluetooth devices and DECT phones. Outside the operating
frequency band and 5% above and below, i.e. the exclusion band according IEC 60601-1-2, section
36.202.3a)4), the short range radio connection is immune up to 3V/m in the frequency range from 80
MHz to 2.0 GHz and up to 1V/m in the frequency range from 2.0 to 2.3 GHz. Depending on the
strength and duration of the interference, the interruption may occur for an extended period. A loss of
connection, due to moving out-of-range, interference, or for other reasons, is indicated with a
TELE DISCONNECT INOP.
Correct channel configuration is important, refer to the Configuration Guide for details.
If a TELE DISCONNECT INOP occurs when the telemetry device goes out-of-range, the INOP will
disappear (without being silenced) as soon as the ECG signal from the telemetry device is available at
the Information Center via standard telemetry transmission.
SpO
2
T Manual Mode
When a telemetry device with a short range radio connection supplies SpO
2
T to the monitor, the
monitor will have a manual measurement mode available. This allows SpO
2
measurements to be made
on request and not continuously, helping to save battery power. To ensure there is no gap in SpO
2
measurements when moving from standard telemetry transmission to short range radio transmission,
the measurement mode will always be set to continuous in this situation unless manual mode is set in
both the telemetry device and the monitor.
Unassigning a Telemetry Transceiver with SRR Adapter at the Monitor
If a monitor and a telemetry device are paired, the assignment and the short range radio connection
will be ended when the devices are unpaired (see “Unpairing the Monitor and Telemetry Device” on
page 199).
If the monitor does not have a connection to an Information Center, you must manually end the
assignment and the short range radio connection.
1 Select the Measurement Selection key.
2 In the Measurement Selection window, select the Tele pop-up key.
3 In the Tele device window select Unassign Tele.
Pairing an MP5 With a Telemetry Interface to a Host Monitor
An MP5 using an IntelliVue Instrument Telemetry interface will be automatically paired when it is
connected to a host monitor and it has been declared as a “telemetry device” at the Information Center
(telemetry equipment label is configured).
When the MP5 is disconnected from the host monitor it will remain paired and the measurement data
will appear at the host monitor in the Telemetry Data window. After the MP5 is disconnected from
the monitor it may take over 15 seconds until its data is displayed at the Information Center.
NOTE Pairing of a host monitor and a telemetry device, with all the related functionality, is only possible
when the host monitor is using a wired LAN connection or a wireless LAN interface (but not using the
IntelliVue Instrument Telemetry interface).
The MP5 can also be paired to a host monitor without a direct connection, as described in “Indirect
Connection - Manual Pairing” on page 195.
