Docking Slots for Cableless Transducers
The Avalon CL base station has three docking slots to hold the CL transducers. The transducers are
charged while docked. The base station has a built-in radio interface with an integrated antenna to
communicate with the transducers.
Pressing the On/Standby button switches the Avalon CL base station between the two modes On and
If you switch the base station to On, the LED button lights up green. The base station is ready for use.
The CL transducers are charging. When the transducers are picked up from their docking slot, the base
station sets up the radio communication to the CL transducer automatically. Wired transducers
connected to the fetal monitor are disabled, and the antenna symbol for the CL transducer is displayed
on the screen of the fetal monitor.
If you switch the base station to Standby, the LED button turns off. The base station is now in
Standby mode. The docked CL transducers continue charging. No radio communication occurs, any
existing radio communication is stopped.
If the LED of the On/Standby button turns red, it indicates a technical problem has occurred that
needs your attention. Check your monitor for a possible related INOP message.
