Maintenance
Maintenance of the Bird 43P is the same as for the Bird 43 except for
battery replacement. Battery life should typically be 48 hours.
If the unit does not function properly in peak mode or if calibration
cannot be achieved, the batteries may be low. Replace with two new
9 V alkaline or lithium batteries. The batteries fit very tightly in their
retaining clips and may have to be pried out one at a time.
