The frmOmni has been designed to be a highly interactive instrument. Investigators familiar with air sampling using microprocessor controlled hardware will havelittle difficulty following the critical paths without further instruction. The second half of this manual comprises detailed operating instructions. As a further aid, it may be helpful to consult the instructions in conjunction with a virtual version of the instrument. 2.0 Specifications.

3.0 Hardware setup 3.1 Battery installation. The main control module is shipped completeready to run. However, in some instances there may be regulations which require the battery to be removed for transportation or not connected. When you unpack the main module, open the front panel door by releasing the two latches and open the panel door. Press the I/O button. If the screen does not light up the battery must be installed/connected. Referring to Figure 3, four Phillips head screws(p/n SC10132) will be observed securing the panel to the internal standoffs.

Figure 3: View of Panel with Door Open Remove the four screws and set them aside for reuse. Gently lift the panel forward, towards your self and swing it to one side. You will find that it is attached to the panel with several wirers. Be careful not to detach any. If the battery is in place but the wires aredisconnected they may now be installed referring to Figure 4. The Battery terminals are color coded and so are the wires. They must match or serious damage could result. Red indicates positive (+) and Black indicates negative (-). If the battery was furnished separately remove it from its wrapping and visually inspect it to ensure that it is undamaged. (If a replacement battery is obtained locally and notfrom BGI it must be a sealed lead acid gel cell, 12 V, 5 Ah, of dimensions which will fit the recess provided). To install a battery, remove the 2 Phillips head screws (p/n OM10128) from the battery clamp (p/n B2686). Lift out the battery clamp, install the battery and replace the clamp and screws. The battery should be installed such that the spade connectors are towards the front of the clamp....
