3.1
BATTERY SELECTION
We recommend the use of alkaline AA batteries only. You will need sixteen fresh
1.5-volt AA-size batteries.
3.2
BATTERY INSTALLATION
To install the AA alkaline batteries, proceed as follows:
1. Open the lid by lifting the two latches located on either side of the carrying
handle.
2. Remove the eight #8 Phillips pan-head screws located on the front panel (Fig.
1, #2) You will need a Phillips-head screwdriver that fits a #8 screw.
3. Gently remove the front panel by grasping the volume control knob (Fig. 1,
#1) and transducer receptacle (Fig. 1, #6) and lifting the panel carefully. Be
careful not to stress the wires connecting the front panel to the battery holders
(Fig. 2, #3). Set aside the entire front panel with electronics attached.
4. Remove the foam padding that covers the batteries (Fig. 2, #4). Locate the
two AA battery holders (Fig. 2, #2), remove them, and install fresh AA bat-
teries (eight in each holder). The battery holders are marked with instructions
to show the correct orientation of the batteries. Make sure all batteries are
installed properly.
5. After the batteries are properly installed, put the holders back into the foam
pad (Fig. 2, #1). Ensure all wires are dressed such that they are not pinched.
Replace the foam padding to cover the batteries (Fig. 2, #4). Replace the
front panel, and reinstall the eight panel screws with moderate tightness (make
sure you do not overtighten them).
Note: If necessary, you can use only one battery pack. The unit will fully operate,
but the battery life will be reduced approximately by half.
3.3
LOW-BATTERY ALERT
The SP-100D is equipped with a unique low-battery alert. As the battery level
decreases, you will start to hear a short tone burst. As shown in Table 1, the tone
burst becomes more frequent as the battery voltage drops, until the voltage reaches
a level where the power shuts off.
