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.
Finally, you can change the number of decimal places on your dB results readout – tap on
Number of Decimal Places and set to either 1 or 2 decimal places, as required. This setting is
for display only and has no effect on the measurement precision or resolution.
When you have made your choices, tap on Display Settings , or on the minus icon , to
collapse the list.
