4Battery: First Assembly and Replacement
Make the measurements
SoundPro®Sound Level Meter Outdoor Measuring System
Make the measurements
1Follow the SoundPro Sound Level Meter user manual to prepare and run your measurements. (Note: This may
require a pre-calibration, setup changes, and pressing the run key or programming an auto-run.)
2When you are ready, place the SoundPro Sound Level Meter in the pocket of the case, verify that the SoundPro
Sound Level Meter is running on external power, and close up the case.
Turn-off and disassemble
1When you are finished, turn Off the SoundPro Sound Level Meter and then turn Off the power switch at the power
distribution panel.
2Remove and disassemble the mast, microphone, and windscreen and place the parts back into the case.
3Remove and store the case plug with O-ring (see 10 in Figure 1/Table 1).
Battery: First Assembly and Replacement
1. Open and unpack the batteries.
•NOTE: The battery is packaged separately from the outdoor kit to
ensure the shipping weight of each carton is under the 70-pound
limit that is imposed by common freight carriers such as Federal
Express (FEDEX) and United Parcel Service (UPS).
2. (Please skip step 2 for first assembly.)
a. If replacing the batteries, disconnect and remove the old batteries.
b. Disconnect the battery’s connectors from the power distribution
panel (see Figure 3).
c. Remove the battery cover as discussed in Step 3.
d. While holding the case open, stand the case on its right side (away from the wheel end).
e. Gently slide the battery out of the compartment (one at a time if more than one battery).
3. Open the enclosure and remove the battery cover.
•Unlatch and open the outdoor system enclosure.
NOTE: The cover is held in place with six Phillips-Head screws. The power distribution panel and the charger
are also mounted on the battery cover. It is optional to remove the shaft segments, the accessory
parts, and some of the foam layers.
•Carefully remove the six larger screws around the perimeter and remove the cover.
4. Install batteries into enclosure.
•While holding the outer enclosure lid open, tip the entire case on its side, so that the wheel-side is up, the
battery enclosure is near the top, and the right handle is on the floor. This will make it much easier to slide the
batteries down into their compartments. Position each battery so that the wires and posts can still be seen as
you slide it into position. Lay the enclosure back down in its normal orientation.
•As displayed in Figure 4 below, it is optional to connect two SoundPro outdoor battery assemblies (see 13 in
Table 1) inside the case for additional battery power.
