Use Priority When Combining Cableless and Wired Measurements
CL Transducers versus wired transducers
CL transducers have priority over wired transducers. If an Avalon CL or Avalon CTS base station is
connected to the fetal monitor, and both wired and CL transducers are connected to the monitor, all
the wired transducers are disabled whenever one CL transducer is active. To switch back to using
wired transducers, switch the base station to Standby mode, or redock all CL transducers at the base
station, and continue monitoring with the wired transducers.
CL NBP and CL SpO

measurements
CL NBP and CL SpO

have priority over the built-in NBP and SpO

CL SpO
2
Pod is activated, the corresponding built-in measurement of the fetal monitor is deactivated.
To switch back to the built-in measurements, switch the base station to Standby mode, or redock the
CL Pods at the base station.
CL F&M Pod versus wired transducers
The CL F&M Pod has priority over wired transducers. If a CL F&M Pod is active, all the wired
transducers are disabled. To switch back to using wired transducers, switch the base station to Standby
mode, or redock the CL F&M Pod at the base station.
About RF Signal Quality
If you cannot get sufficient ultrasound signal quality using the Avalon CTS base station, try
repositioning the transducers, or switch to wired transducers.
Using an Avalon CL base station you should get a better signal by reducing the distance between the
CL transducer and the base station.
Signal transmission can be disturbed if:
• the patient is out of range of the receiving area.
• there is interference from another, possibly stronger, RF signal (a broadcasting station, for
instance).
• the patient is near material that absorbs electromagnetic waves (for example, metal-reinforced
concrete, elevator doors) or the base station is in an enclosed metal rack.
