alkaline batteries. (See Figure 13.)

Figure 13 - Battery Replacement

Remove the battery "plug" using a large screwdriver. Insert the blade of the screwdriver into the slotted plug,

push the spring-loaded plug in gently, then rotate the plug one-quarter turn either direction. The plug and spring

will come out followed by the batteries. Insert the new batteries by tilting the tower section at an angle of

approximately 45-degrees. A steeper angle will cause the batteries to impact the top terminal too forcefully

denting the positive terminal of the batteries. This may cause the batteries to leak or create a faulty electrical

connection. Slide the batteries in, positive end first, and then replace the spring-loaded plug using the reverse

procedure.

The red LED voltage indicator light on the tripod tower will remain illuminated when the battery voltage is higher

than 10.7 VDC. The precise battery voltage can be determined in two ways: (1) view the Weatherpak Status

, (2) with the ALOHA

plume model open on the PC, drop down the

[MISC] menu to "Processed Sam Data". One of the items shown is battery voltage. With new batteries

installed, the voltage should be between approximately 13 and 15 volts.

Tower Fuse

5-3.2

The in-line fuse is located in the tower junction box (see Figure 14). Gain access to the fuse holder by removing

the two machine screws on the junction box faceplate; then carefully separate the faceplate from the junction

box. Inspect the in-line fuse and replace if necessary with a 3AGC fuse.
