Warnings and Safety Precautions
Warning!
•
For patients with implanted electronic device electrical stimulation treatment is
to be carried out only after having checked any risks.
•
Jewellery and eyeglasses have to be taken off during the treatment.
•
Turn off cellular phones and radiophones or place them in a distance of 3 m
from the device.
•
Cardiac pacemakers are extremely vulnerable. Here the therapy should only be
carried out under continuous pulse and ECG control.
•
If the patient and/or the patient cable is in the direct range of a high-frequency,
short-wave or micro-wave therapeutic device, a damage to the device or an in-
jury to the patient cannot be excluded. Please keep a clearance distance of 3 m.
•
A simultaneous connection of the patient to a high-frequency surgery device
can lead to burns under the electrical stimulus electrodes.
•
It is recommended not to exceed the current density of 2 mA/cm
2
on all
electrode surfaces.
•
For current types with the threat of cauterization (all currents with galvanic
portion), the maximum recommended current density is 0.5 mA/cm
2
electrode
surface. For galvanization the limit value is 0.2 mA/cm
2
and for iontophoresis
0.1 mA/cm
2
.
•
Do not use disposable (self adhesive) electrodes with currents with galvanic
portion since there is the threat of cauterization!!
•
The unit is not designed to be operated in places with the inherent risk of
explosions. If it is used in dangerous areas of anesthesia departments, the
possibility of an explosion cannot be excluded.
•
In case of short circuit the lithium battery, the battery can explode. Only service
staff should change the battery.
•
In case of any visible failure contact
gbo Medizintechnik AG or one of the service agencies authorized by gbo
Medizintechnik AG immediately
.
Safety of service personnel
Warning!
•
Take care that the mains cable is unplugged before any components are
removed or exchanged
•
In case of service operation with the open unit keep care about high voltages
•
The power supply may have the supply voltage (100 – 240V) on the metal parts
•
The current amplifier boards produce the ±200 V by an internal switching
regulator
•
The display backlight inverter generates high voltages, take care not to touch
contacts during normal operation
