4.4.3. Actions in case of problems
Proceed as follows in case of functional problems:
1. Immediately disconnect the patient from the HF device.
2. Inspect the HF device and perform a functional test.
3. Report incidents and near-accidents to the German Federal Institute
for Medications and Medical Products in accordance with Section 3 of
the German Ordinance on the Installation, Operation and Use of
Medical Products (MPBetreibV). Observe the provisions of the in-
house reporting system in this regard.
4. Consult the Technical Service department, see Section Technical
service, page 109.
In an emergency, the HF device can be switched off at any time by the
power switch 31, which fully disconnects the device from the mains.
4.5. Neutral electrode monitoring
Always use the largest possible electrode when attaching a neutral
electrode.
4.5.1. General information
BOWA recommends using split neutral electrodes, since only this type of
electrode allows the HF device to detect detachment of the neutral
electrode if this occurs.
Monitoring of the neutral electrode minimizes the risk of burns at the site
where the neutral electrode is attached.
Two types of neutral electrodes can be monitored:
 Split electrodes for infants (for use with reduced power)
 Split neutral electrodes
The type of neutral electrode and its contact quality are selected and/or
shown in Neutral Electrode Modes menu.
