11 Turning The AreaRAE Plus/Pro On And Off

11.1 Turning The AreaRAE Plus/Pro On

With the instrument turned off, press and hold the [MODE] key until the beep sounds and the display and

LED alarm lights turn on. Then release the [MODE] key.

A RAE Systems logo (or a company name) should appear first. This is followed by a progression of

screens that tell you the AreaRAE Plus/Pro’s current settings.

11.1.1 Pausing To View Screens During Startup

Press the [MODE] button anytime during the startup sequence to pause the progression. This allows you

to view the information for as long as you like. To resume the progression, press [MODE] again. Even if

you pause the progression of screens, the startup process is not interrupted.

Note: To speed up the startup time, the number of screens shown on startup can be reduced by enabling

the Fast Startup option under Programming/Monitor.

Then the AreaRAE Plus/Pro’s main reading screen appears. It displays instantaneous readings similar to

the following screen (depending on the sensors installed) and is ready for use.

Note: If the battery is completely empty, then the display briefly shows the message “Battery Low,” and

the AreaRAE Plus/Pro shuts off. You should charge the battery or replace it with a fully charged battery

before turning it on again.

11.2 Turning The AreaRAE Plus/Pro Off

Press and hold [MODE]. A 5-second countdown to shutoff begins. You must hold your finger on the key

for the entire shutoff process until the AreaRAE Plus/Pro is powered off.
