12.2 Operational Controls
The Safe-PocketSource is designed to be simple to use and as such has only a power on/off
button- (Press for On & Press and hold to turn off) and a LED and a variable dial. The LED
shows Green to show the source is switched on and working and that the battery level is ok.
The LED will turn Red when the battery life is low and will extinguish once the batteries are
exhausted.
To change the activity level use a small flat blade screw driver to rotate the dial to the
desired setting.
12.3 Maintenance
The Safe-PocketSource 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 rear of the
instrument -this clips in – (it is a little difficult sometimes to get the door on!) The Safe-
PocketSource 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.
LED is lit green when
battery is good and
turns red when
batteries are low.
