Fig.8.2

Display Settings screen

You can select the optimum choice of brightness for the traffic light (for example, High in

bright light conditions and Low in dark conditions) and you can select whether to have

backlight on the keyboard, or not. In very bright lighting conditions you will not be able to see

the backlight, so set it to Off to save some power.

A link is also provided in Display Settings to adjust the touch-sensitive screen. Tap on Adjust

Touch Screen > to display a full screen with guidance on how to tap on a cross five times at

different places on the screen. At the end of the adjustment procedure you can save the values

or cancel the adjustment.

To change the number of decimal places on your dB results readout between 1 and 2 decimal

places, or to change the number of digits on your engineering units readout between 3 to 4

digits, tap Resolution of Readings and set to Normal or Extended, as required.

When you have made your choices, tap on Display Settings, or on the Minus icon , to

collapse the list.
