The key interface features are as follows:

1. System check: Flashes green periodically while the PED is

functioning correctly. The LED flashes red if the instrument is in a

critical status.

2. Dose rate alarm: Flashes amber while the amber dose rate alarm is

exceeded. Flashes red while the red dose rate alarm is exceeded.

3. Dose alarm: Flashes amber or red for active dose alarms and

continues to flash until the data has been transferred to

DoseVision™.

4. Readings screen: The screen can be programmed to customise the

information to display using DoseVision™.

5. Case: The case is a robust and durable polymer case.

6. Button: PEDs use a single button for selection and navigation. A

long press is used to turn on the PED, open the menu system and to

make selections. A short press is used to scroll. The button is also

used to silence alarms and clear pop-up messages (PED+ and PED-

ER+).

7. Speaker: The speaker is used for audible alarms and the activity

sounder.

8. Geiger Müller tube window: The Geiger Müller tube has a small

window to allow increased low energy response.
