Instruction Manual
Taking a closer look at the instrument
The Nor103 is delivered assembled and ready. We recommend that the microphone
is always mounted on the preamplifier as this will prevent dust and dirt to enter the
insulator around the sensitive signal terminal on the microphone.
Always keep the instrument turned off if you are required to unscrew or screw the
cartridge on the preamplifier. Screw only finger tight!
The instrument is powered from two AAA size batteries which are inserted as shown
on the figure.

Use of batteries
The sound level meter comes with two AAA batteries.
Battery lifetime is typically 8 hours (depends on use and brand of batteries).
The use of alkaline or lithium batteries is strongly recommended to avoid leakage.
Rechargeable batteries may also be used, but with reduced operating time.
If the instrument is stored for a prolonged period of time, we recommend removing the
batteries to avoid damage from leaky batteries.
Data are stored in a non-volatile memory and will retain its content independent of the
batteries.
Switch on and off the instrument
Press the POWER key in the lower right corner of the instrument to turn the power on.
A second operation, hold for 0,5 seconds or more, will switch the instrument off.
