• Never selectively replace batteries; always replace all of the batteries at the same time with
new batteries. Batteries should be checked with a voltmeter or battery tester to confirm
proper voltage.
• Leaky batteries may have damaged the battery contacts in the battery box.
• Check to see that the battery tray is screwed tightly onto the base of the instrument. Also,
the fit between the battery prongs and the batteries may need adjustment, as this fit may
vary over different brands of battery (especially Energizer™ brand, as they are larger in
diameter, preventing a proper connection).
• Alkaline batteries are recommended for the best performance and storage life.
Rechargeable batteries such as Nickel-Cadmium will provide performance, but are not as
desirable due to their lower terminal voltage. Low cost standard Carbon-Zinc batteries may
be used in emergencies, but they should be replaced with alkaline batteries when available.
Rechargeable Battery Pack: For maximum battery life, the battery pack must contain a full charge.
Properly charged, the battery pack will provide approximately 14 hours of service. The batteries
will begin to perform optimally after five full charges and discharges.
Instrument does not rotate or self-level, or produces "Error" messages: Ensure that the instrument
is within its self-leveling range. Reset the internal processor by turning power off, wait 15 seconds
and power the instrument on again. If the instrument rotates but does not self-level, be sure that
Auto Level Mode is NOT set to OFF on Model 3175, or that Manual Mode is not selected for Models
3110-GR and 3150.
If troubleshooting is not effective, please contact David White® or an authorized service center
for assistance.
