Switching on

Connect the mains power supply to a socket and switch on
the power.
The Green Power Indicator on the Receiver unit will light up
and the instrument will start.
When the instrument has booted, the display will switch to
showing noise levels.
At the top of the screen the instrument will show Noise
Nuisance View.
The main display will show the current sound level as a 1
second LAeq value and the graph below shows the noise
profile or time history.
When the instrument is not running or recording, this graph will be displayed in green
with yellow markers above showing the peak noise levels.
The instrument is not recording or storing data at this point.
If a measurement is not started within 10 minutes, the instrument will
automatically start itself and will begin to record noise levels.

Check the instrument clock

All of the noise measurements and audio recordings made by the Trojan LITE are stamped
with the current time and date. It is important that the internal clock in the instrument
is set correctly.
At the bottom of the main screen, above the three soft keys, is the current time and
date of the instrument. If this is not correct, press the menu key and select Set Clock.
Follow the instructions on screen to set the time and date.
Press OK and Back to return to the main screen.

Memory Size with audio recordings

Audio recordings take up much more memory than the noise levels measurements and
so the Trojan LITE is fitted, as standard, with a 4GB internal memory card.
This allows the instrument to store up to 24 hours of audio recordings. The instrument
will also store 30 days of noise level measurements alongside the audio recordings.
