8.3 Maintenance
The Safe-EPD does not contain any user serviceable parts and as such no repair or
adjustment should be attempted as this will both invalidate the warranty and lead to
potential damage of the circuit.
The batteries are accessed through the panel on the side of the instrument. The Safe-EPD
uses 2 alkaline AAA cells, professional or long life cells are recommended for best
performance. Batteries should be removed when not in use for prolonged periods and
partially discharged cells should never be mixed with new cells.
ENSURE CELLS ARE CORRECTLY FITTED – Observe the polarity markings on the case, the +
sign indicates that the cell should be placed with the positive terminal facing the battery door
aperture.
