a) To the top of your 2250-M:
i) Connect the microphone cable to the front socket of your Type 2250-M. Please note
that there is a red dot on the underside of the LEMO silver connector and this should
be lined up with the corresponding white dot located on the back panel of your 2250-
M. Please also note that this is a captive plug and the spring - loaded collar on the
silver plug should be used to remove the connection – do not pull on the cable.
b) To the base of your 2250-M:
ii) Insert a memory card. You can use either a Compact Flash (CF) or Secure Digital
(SD) memory card to store both the measured noise results and the sound recordings.
A 512MB SD card is supplied with your system. Smaller and larger capacity cards are
available and please consult our website for advice on “Compatible SD and CF
memory cards”: http://www.bksv.co.uk/?ID=3556.
The locations of the card slots are shown here:
Please note the SD-cards must be mounted with the card label facing downwards.
iii) Connect the plug of the power cable marked “DC In” to the right-hand socket
marked below.
CAUTION: This plug is captive so that if you wish to remove it, pull on the
