The Personal Computer linked with the Wave Plus system has to comply with IEC 60950
regulation and has to be placed outside the patient’s area. The use of Personal Computer
non-complying with IEC 60950 is allowed using a medical class insulation transformer to
power the PC. The software (produced and commercialized by third parties) has to com-
ply with the CE93/42 regulations for medical devices.
4.3 LED signalling during operation
4.3.1 Base unit LEDs:
During Wave Plus functioning, LEDs are used to indicate the functioning status of the system.
On the base unit front panel there are eighteen bicolour LEDs:
- LED off: the correspondent electrode is in stand–by (non active);
- LED on, green light: the electrode is on;
- LED on, orange light: the electrode is on and the battery is low.
4.3.2 Electrode unit LED:
On the EMG unit there is one LED:
- LED off: the electrode is in stand–by condition (not active);
- LED on, green light: the electrode is on and recognised by the receiver unit;
- LED blinking green light: the electrode is on and the battery is low.
The LED of the transmitting module, when the electrode is placed on the charging cradle, also carries an
indicator function of the charging phases. In this case the color of the LED is orange. For more informa-
tion, refer to the battery charger chapter.
4.4 Pre-gelled electrodes
The Wave Plus system can be used with single-use pre-gelled electrodes equipped with snaps. Pre-
gelled electrodes are available in different dimensions, and may be purchased through local distributors
of consumable medical accessories.
To apply electrodes see the information provided by the manufacturer.
