HEINE NT4 Mode D'emploi page 7

Reduction rings for:
BETA 4 NT BETA 4 SLIM / F.O. 4 SLIM LED NT / F.O. 4 SLIM NT
Standard Laryngoscope handles do not require a reduction ring.
After use, the handle can be replaced into the charging slot and remain there. Handles cannot be
overcharged.
The device must be disconnected from the mains supply when the adaptors are being fitted.
If the second charging compartment is not in use it can be sealed off by the dust cap which is supplied with
the unit.
The pulsating charge indicator (light ring) around the charging slot, indicates that a charging current is flowing
and the battery is charging. The charging process takes place in accordance with the JEITA* temperature
standard for Li-ion batteries. This can lead to short-term charging interruptions at ambient temperatures
> 30 °C which optimizes the battery life.
( * Japan Electronics and Information Technology Industries Association)
A constant light around the charge indicator indicates that a HEINE handle is present but no charging
process is taking place.
The charge indicator does not light up when the charging slot is empty or a malfunction is present.
If a fully charged handle remains in the charger, there will be brief recharging cycles (< 5 min) this is visible
from the flashing of the charge indicator. The handle is fully charged and ready for use.
The LED indicates the operational readiness of the power supply.
The charger may only be operated with the mains voltage specified on the nameplate of the power supply.
Unplug the unit from the mains if not in use over long periods.
In the event of fluid ingress in the housing, the charger should be taken out of service and checked
by an authorised person.
Follow the instructions for the charger and rechargeable handles.
When replacing the handles in the charging compartments, ensure that the internal contacts in the
compartment are clean and that the instruments are switched off.
The rechargeable battery can only be charged when fitted to the handle.
The HEINE Charger is intended for installation in medical areas outside the patient environment
(at least 1.5 metres from the patient or patient support pursuant to IEC 60601-1, see figure).
