Operation / Maintenance
Metal Finding Tips:
" Always calibrate in air for best sensitivity.
" When scanning for deep metal members near 8 cm deep
scan in both, horizontal and vertical directions. Metal
sensitivity is sometimes increased when the metal ob-
ject aligns with the sensor.
Depending on the proximity of the electrical wiring or
pipes to the wall surface, the UNITEST Wallscanner
may detect them in the same manner as studs, etc. in
the DEEP and NORMAL Settings. With the use of metal
and continous AC detection, pipes and electrical wiring
may be detected adequately. However, caution should
always be used when nailing, cutting, or drilling in
walls, floors and ceilings that may contain these items.
The UNITEST Wallscanner will not detect hot wires in-
side metal pipe or conduit, or behind some plywood or
thick wall sections.
Always turn off the power if drilling or mounting oper-
ations near electrical wires.

5.0 Maintenance

When using the instrument in compliance with the instruc-
tion manual no special maintenance is required.

5.1 Changing the Battery

Low Battery and Sensitivity Test:
To test the UNITEST Wallscanner's battery strength and
sensitivity, place the UNITEST Wallscanner in NORMAL
mode and hold the UNITEST Wallscanner away from any
surface. Press and hold the activation switch until the bar-
graph is in the display. Then let the activation switch go.
Move the palm of the free hand towards the back of the unit.
When the hand is approximately 5 to 6 cm away from the
back of the UNITEST Wallscanner, the LCD bars should
begin to move towards the midpoint of the display. Moving
the hand away should cause the bars to return to the side of
the diplay. If the bars do not react accordingly, it is time to
replace the UNITEST Wallscanner's battery. If the symbol
appears in the display, replace the discharged battery.

lable)
" Connect the battery to the battery clip and insert the bat-
tery into the UNITEST Wallscanner

With normal use, one 9-volt battery should last ap-
proximately two years.
Please think of our environment when you dispose of your
used batteries. They belong in a rubbish dump or a refuse
collection place for hazardous waste.
Please, comply with the respective valid regulation re-
garding the return, recycling and disposal of used batter-
