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.
