When the QRAE II is ready for use, it shows this screen:
Note:
If datalogging is off, you will not see the datalogging icon (see icons, page 10).
Inverting The Display
The QRAE II is easy to read, whether held in the hand or clipped to a belt. To flip the
screen, press the [Y/+] key and hold it down for 3 seconds. When the image inverts,
release the key.
Testing The Alarms (Anytime)
Under normal non-alarm conditions, the buzzer, vibration alarm, LED, and backlight can
be tested at any time by pressing [Y/+] once.
Turning The QRAE II Off
Press and hold [MODE]. In 2 seconds, a 5-second countdown to shutoff begins. You
must hold your finger 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 QRAE II
continues normal operation.
The countdown proceeds as follows, accompanied at each step with an alarm beep and
light flash. The display shows the countdown in sequence:
Unit off in 5 seconds...
Unit off in 4 seconds...
Unit off in 3 seconds...
Unit off in 2 seconds...
Unit off in 1 seconds...
Unit off in 0 seconds...
Unit off...
When you see “Unit off...” release your finger from the [MODE] key. The QRAE II is
now off.
Caution: The alarm is very loud. During shutdown, you can mute most of the sound by
holding a finger over the alarm port.
