Putting the Optimus Sound Level Meter into the kit case
Care needs to be taken when removing the preamplifier from the sound level meter, because it
is delicate and can easily be damaged.
Only the locking ring at the base should be turned. The microphone capsule is also delicate and
must not be knocked.
It is easy to get the wires trapped when closing the lid, so please take care to keep them away
from the edge of the kit case when shutting it.
Refer to the Optimus Sound Level Meter User Manual for more detailed information regarding
the care and operation.
Gently unscrew the preamplifier and microphone from the optimus and stow it in the hole in the kit case to
keep it safe.
Connecting the Sound Level Meter
The optimus sound level meter is connected to the outdoor kit case using two cables.
1.
Microphone input
2.
Multiway input
The grey rubber protective compartment cover on the base of the optimus can be removed completely while it
is in the case.
Microphone input to the Sound Level Meter
The microphone signal is connected to the sound level meter via the 6-pin socket at the top of the instrument.
Carefully fit the 6-pin connector to the socket and tighten the locking ring. Do not twist the connector or use
excessive force. This may cause damage to the connector and the sound level meter.
