Install / Replace Batteries in BATT
Figure 9
The 2000-BATT requires four “D” size batteries and should operate
for six months before replacement. An internal beeper sounds
momentarily each minute when the battery supply discharges
below 4.5 volts. Replace batteries as follows when this occurs:
1. Pull and remove the front two rubber feet underneath the unit.
2. Loosen, 1 to 2 turns, the two phillips-head screws located 1.5
inches directly inside the rubber feet mounting holes.
3. Slide the bottom battery compartment outward (to front) and
down, to get to the batteries. (See Figure 9.)
4. Replace the four “D” size batteries. Be sure the batteries are
installed with proper polarity (+/-) as marked on battery holder.
5. Re-install the battery compartment on the bottom of the
recorder, aligning the holes with the screws. Press the
compartment firmly to the back (inward), tighten the two
Phillips-head screws, and re-insert the two rubber feet.
