Revision A, January 2006

Read Before Operating
This manual must be carefully read by all individuals who
have or will have the responsibility of using, maintaining,
or servicing this product. The product will perform as
designed only if it is used, maintained, and serviced in
accordance with the manufacturer’s instructions.
CAUTION!
To reduce the risk of electric shock, turn off power and remove
batteries before removing the monitor cover. Never operate this
monitor while the cover is removed. Remove monitor cover and
sensor modules only in an area known to be non-hazardous.
WARNING
To prevent ignition of flammable or combustible atmospheres,
disconnect power before servicing.
WARNING
Do not mix old batteries with used batteries or mix batteries
from different manufacturers.
WARNING
Substitution of components may impair intrinsic safety.

Warnings
For safety reasons, this equipment must be operated
and serviced by qualified personnel only. Read
and understand the user manual completely before
operating or servicing.
Computer Interface
Do not transfer data by means of the Bluetooth®interface in
hazardous atmospheres.
Static Hazard
Clean only with a damp cloth.
Long-Term Storage
Reliable performance of this radiation detector is based upon
regular usage. For long-term storage, the battery should be
disconnected. Preparation for use after long storage requires
installation of the batteries and a warm-up period of at least
10 minutes for the sensors to equilibrate. The user should
recognize that sensor life is based upon the purchase date.

Avertissements
Pour des raisons de sécurité, cet équipement doit
être utilisé, entretenu et réparé uniquement par un
personnel qualifié. Étudier le manuel d’instructions
en entier avant d’utiliser, d’entretenir ou de réparer
l’équipement.
Câble de Computer
Ne transférez pas les données au moyen de l’interface de
bluetooth en atmosphères dangereuses.
Danger Risque D’origine Electrostatique
Nettoyer uniquement avec un chiffon humide.
Stockage à Long Term
Le fonctionnement durable de ce détecteur de rayonnement
est conditionné par une utilisation régulière de celui ci. Lors
d’un stockage à long terme, la batterie doit être déconnectée.
Le rédémarrage aprés une longue période d’arrêt, nécessite la
réinstallation de la batterie, et une période de chauffage de 10 mn
afin que les capteurs se mettent à l’équilibre. L’utilisateur doit être
conscient que la durée de vie indiquée pour le capteur démarre à
sa date d’achat.

General Information
The NeutronRAE II an intrinsically
safe rapid detector of γ-ray (gamma)
and neutron radiation sources. Because
of its high sensitivity, it can alert
rst responders to the presence
of a radiation threat well before
they might be exposed to health-
threatening levels. It is the only
personal radiation detector with a loud
audible alarm, big, bright ashing
LEDs, and a vibration alarm. For stealth operations, law
enforcement personnel can disable each alarm separately.
NeutronRAE II’s water-resistant design makes for reliable
operation in wet environments. Its sensitive Cesium Iodide
(CsI) and Lithium Iodide (LiI) scintillators provide fast (less
than 2 seconds for gamma/5 seconds for neutron) response to
radiological threats.
The NeutronRAE II accumulates approximate dosage. Stored
dosage data can be cumulative or cleared and reset for each
use period.

Inserting & Replacing Batteries
NeutronRAE II uses twoAAalkaline batteries as its power
source (use only Duracell MN1500 or Energizer
E91). To change the batteries:
1. Use a coin or screwdriver to open the
cover on the side of the unit. Turn the
screw counterclockwise to loosen the
screw, and then tilt
the cover off.
2. Insert batteries into
the compartment
according to the
legend on the rear of the NeutronRAE II, making
sure the batteries’polarity is correct.
3. Replace the cover and turn the screw
clockwise to secure the cover.
Note: When you touch the cover’s internal
contacts to the batteries, NeutronRAE II’s alarm
sounds briey, indicating that the batteries are
not dead. If the sound is distorted or irregular, the batteries
should be replaced.

User Interface
NeutronRAE II’s user interface consists of the display, LEDs,
alarm transducer and two buttons, labeled MODE and SET.
The LCD display provides visual feedback that includes
time, functional mode, battery condition, and gamma
radiation measurement.
