Installing The Antenna 
 
Lift the rubber cover on the top of the AreaRAE Pro/Plus 
that protects the antenna port. Hold the base of the 
antenna and align it with the mating jack in the port. 
Then screw the antenna onto the jack until it is snug.
 
 
 
Turning The AreaRAE Pro/Plus On 
 
With the instrument turned off, press and hold the 
[MODE] key until the audible alarm stops, and then 
release. During startup, the battery, buzzer, and LEDs 
are tested, and then it performs self-testing of its other 
functions. When the main measurement screen appears, 
the instrument is ready for calibration or use. 
 
Note: When the battery’s charge falls below a preset 
voltage, the instrument warns you by beeping once and 
flashing once every minute, and the “empty battery” 
icon blinks on and off once per second. You should 
charge the battery or replace it with a fully charged 
battery before turning it on again. 
 
Note: If Fast Startup is enabled on the instrument, 
fewer screens are shown during startup, compared 
to Normal Startup sequence. 
Turning The AreaRAE Pro/Plus Off 
 
Press and hold [MODE]. A 5-second countdown to shut-
off begins. You must continue pressing on the key for the 
entire shutoff process. If you remove your finger from the 
key during the countdown, the shutoff operation is 
canceled and the instrument continues normal operation. 
 
When the countdown ends and the screen displays “Unit 
Off,” release your finger from the [MODE] key. The 
AreaRAE Pro/Plus is now off. 
 
 
Testing The Alarms 
Under normal-operation mode and non-alarm condi-
tions, the buzzer, LEDs, and backlight can be tested 
anytime by pressing [Y/+] once. If any alarm does not 
respond, check the Alarm Settings in Programming 
Mode to make sure all alarms are enabled. If any 
alarms are enabled but are not functional, do not use 
the instrument. 
Glance Mode For Quick Information 
 
Glance Mode allows you to get vital information 
without turning on the AreaRAE Plus/Pro. You can 
check information such as the instrument’s model 
and serial number, installed sensor types, wireless 
modules installed, etc. Glance Mode can be 
enabled/disabled via ProRAE Studio II on a 
connected PC. 
 
Using Glance Mode 
With the AreaRAE Plus/Pro turned off, press and 
hold [Y/+] to enter Glance Mode.  
Every screen is 
displayed in sequence as configured. Press [N/-] 
to advance to the next screen. The AreaRAE 
Plus/Pro exits Glance Mode and turns off  when you 
press the [MODE] key. In addition, if you do not 
press either key in 60 seconds, the AreaRAE 
Plus/Pro automatically exits Glance Mode.
