Note that to receive the best result, place the phone on a flat surface in a windless environment preferably for 5 minutes. Note: If your phone is being charged, the radio or an active call is on, the thermometer shows no temperature. Sound meter The Sound meter can only measure the approximate level of the real dB level. The phone displays a vertical meter bar that shows the noise level graphically. There is also a numerical presentation of the sound level. The peak value is shown in a frame on the top and the current value is presented underneath. Note: It is not possible to measure the estimated noise level of a call in progress. Also, you can not use Sound meter when a headset is connected. When you press Options you get a list of four choices: • With Reset peak you can reset the peak value. • With Hold peak both values are shown but the peak value is updated only when the current noise level is greater than the peak value. • With Dynamic peak both values are shown but the peak value is valid only for 5 seconds • With Noise tuning you can simulate the sensitivity of hearing mechanism for different frequencies. You can choose between low noise (sounds < 85 dB) and loud noise (sounds > 85 dB). Copyright © 2003 Nokia. All rights reserved. 95
