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 performance.
This product complies with Part 15 of the FCC rules. Operation

!
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.

General Information
The NeutronRAE II is a rapid detector
of γ-ray (gamma) and neutron radia-
tion sources.
sensitivity, it can alert rst responders
to the presence of a radiation threat
well before they might be exposed
to health-threatening levels.
personal radiation detector features 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
response to radiological threats.
The NeutronRAE II accumulates dosage. Stored dosage data
can be cumulative or cleared and reset for each use period.

NeutronRAE II Features
Inserting & Replacing Batteries
NeutronRAE II uses two AA alkaline 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.

Turning NeutronRAE II On and Off
Turning NeutronRAE II On
Press and hold the MODE button for 3 seconds. As
NeutronRAE II starts up, the following occur:
1. A long beep sounds (if the buzzer is set to On), and
unit information and the current rmware version are
displayed. The LEDs and vibrator undergo a self-test.
2. Unit self-check. The time and battery status are
displayed:
During the 20-second self-check, the detector checks
that the gamma and neutron sensors are functioning
properly. If so, the messages “Gamma sensor OK!”
and “Neutron sensor OK!” are displayed.

or
If the sensor is damaged or not functioning properly,
the message “Gamma sensor failed” or “All sensors
failed” is displayed, turn the unit off and contact your
distributor or the RAE Systems service department.

or
Important! If your NeutronRAE II displays
“Gamma sensor failed,” “Neutron sensor failed,” or
“All sensors failed!” contact your distributor or RAE
Systems service at 408-952-8200. Do not attempt to
use or repair the unit. There are no user-serviceable
parts in the NeutronRAE II.

Turning NeutronRAE II Off
Press the MODE button and hold for 5 seconds. The detector
counts down 5 seconds and then turns itself off. Do not
release the MODE button until the unit counts down to zero
and the display reads “Save cong...” and “Stop unit...”
Flipping the Screen

Operation
The NeutronRAE II has two modes: Normal Operating Mode
and Programming Mode. Normal Operating Mode is the
default; see Programming Mode, on page 20, for details on
entering and using Programming Mode.
Normal Operating Mode
In Normal Operating Mode, the NeutronRAE II detects gamma
and neutron radiation and accumulates gamma radiation dosage
data. In Normal Operating Mode, pressing the MODE button
sequentially steps the unit through the following functions:
NORM Normal Operating Mode
CAL
PEAK Maximum radiation levels detected since last cleared
MIN Minimum radiation levels detected since last cleared
DOSE
TIME Time, date, and time unit has been on
STAT Detector status (battery voltage and internal temp.)
COMM
TEST Self test (if Diagnostic Flag is set during start-up)
Each function remains active for 60 seconds before
automatically returning to the Normal Operating Mode.
Pressing the MODE button changes the selection from one
function to the next one in the sequence.
