Range of applications:
The HEINE NT 300
®
is designed exclusively for charging
HEINE rechargeable handles.
Please note: The performance of this instrument can only be guaranteed
if genuine HEINE instruments and spare parts are used.
General safety:
Under no circumstances should the mains transformer housing
or charger be opened. Repairs may only be carried out by qualified personnel
(exception: changing the rechargeable battery).
Safe installation:
The charger must be placed on a solid surface. Do not place
the NT 300 on soft furniture, cloth or carpet. Do not insert any objects in any
opening in the housing.
Safety in use:
The NT 300 may only be used at the mains voltage specified on
the identification label. Unplug the unit from the mains if not in use over long
periods. If liquid enters the housing, ensure that the unit is tested by authorized
personnel immediately. The NT 300 must not be used in rooms where an
explosion hazard is present.
The following handles are not compatible with the NT 300 charger:
BETA TR, BETA R, BETA cord handle.
Installation and use
– The NT 300 fulfils the requirements regarding the electromagnetic compatibility.
However, its function might be affected by electrical and magnetic fields, such
as those which occur in connection with radiological devices or mobile tele-
phones.
– Plug the mains transformer into the mains and the charger is ready for use.
– NT 300 ensures that batteries are kept in good condition irrespective of handle
size.
– 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.
– Instruments placed next to each other must not touch each other.
– If different-sized handles are used, it is possible to fit adaptors so that each
handle is held in place correctly. The NT 300 must be disconnected from the
mains supply when the adaptors are being fitted.
– Ideally, the rechargeable handle should always be replaced and stored in the
charger. Handles cannot be overcharged.
– The rechargeable battery can only be charged when fitted to the handle.
– 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 light around the charging compartment shows that current is
flowing and that the battery is being recharged.
– When the light is permanently lit, the charging sequence is completed. The
battery in the handle is fully-charged and is ready to supply maximum power.
– If the light is switched off, this indicates that the charging compartment is
empty or the unit is defective.
Cleaning and Maintenance
– We recommend that external surfaces of the NT 300 be wiped clean with a
disinfectant cleaning wipe. This should only be carried out by qualified
personnel.
– Any disinfectant used must be approved by the disinfectant manufacturer for
use on plastics. The manufacturer`s instructions must be followed.
– The external surfaces may also be wiped clean with a cloth moistened with
water or with a neutral pH or slightly alkaline cleansing agent.
– Isopropyl alcohol may only be used at concentrations up to 70%.
– Spray disinfection and soaking are not permitted and may cause damage.
– The article can be neither machine-cleaned, nor thermal disinfected or sterilised.
These processes lead to irreparable damage to the product.
