3 Basic Operation
Radio Range of CL Transducers
The CL transducers have an operating range around the base station of at least 100 m/300 ft in the line
of sight. Obstructions such as walls, metal doors, elevators, and other environment structures can lead
to signal loss. The Tele symbol indicator and the
"Screen Elements" on page 46 and "Tele Info Window" on page 82) provide information on the
status of the signal strength.
When a patient is approaching the end of range, the US sound is replaced by an artificial QRS sound
(like DECG), and the DECG and MECG waves are no longer displayed on the monitor.
Out of Range
If the patient walks out-of-range, the CL transducer LED lights up cyan and after 15 seconds a two-
tone audio signal is emitted. At the monitor the INOP e.g.
Transducer finder LED - lights
up on the transducer providing
the measurement source.
