4. AC Wire
Press
key to switch to AC detection mode
Only AC wires (>110V, 50~60Hz) can be detected
Only solid wires can be detected, not for twisted pairs
5. Turn On/Off Alarm Tone
Short press
key to turn on/off alarm tone;
Turn on/off backlight
Long press
key to turn on/off the screen backlight (press and hold
the key for 3s)
6. Battery Installation and Replacement
Screw off the fastening screws and open the battery cover upwards, install
3 AAA batteries (alkaline) inside, please note the polarities.
Battery level:
Full
2/3 full or less
1/3 full or less
Replace with new
7. Calibration
When you move the detector close to an area without metal objects, but
you can that the scale bar is full and with alarm, that probably it’s
interrupted by the environment, in that case, please calibrate the detector
by manual and restore it to factory setting.
a) Firstly don’t put the detector close to the wall surface, just hold it in an
open air, no touching or covering on the detecting area (I).
b) Short press
key in auto mode, and
key in metal mode, if
you see that the scale bar becomes full and then disappears, entering
standby status, it indicates the calibration is completed.
c)
Error might also happen if the battery is not enough, 1/3 battery level
is required at least.
Cautions
1
）
Before turning on the detector, please ensure no water on the area to
be detected, use cloth to wipe up if necessary, don’t let any wet get inside
the device, keep it away from the direct sunshine;
2
）
Don’t use the detector in extreme weather, if there is great difference in
temperature; Don’t use the detector until its temperature is close to the
environment;
3
）
Keep away from electric tools or transmitting devices such as WLAN,
UMTS, flying radar, launching tower, microwave oven and other devices of
such property;
4
）
Take out the batteries when not used, to prevent battery leakage and
corrosion;
5
）
Precision and depth might be weakened by environment factors such as
wall constitutions (metal building materials, current conducting wallpapers,
ceramic tiles or sound absorbing materials), big water content, and quantity,
sort, size and position of the object(s), all of them shall affect the detection.
Hence it’s advised to take necessary protective measures according to
other notices before boring or cutting the wall;
6
）
Keep the sensing window (J) clean, it fails to sense whether it’s close to
the wall surface if it’s dirty or covered;
7
）
It is easier to detect the live wire if it has been connected to working load
(such as lamp or electric appliance). It’s hard to detect the live wires laid
inside some walls that can isolate the current;
8
）
Static electricity might cause inaccurate detection, in order to improve
the detection, you may put your other hand flatly close on the wall surface
beside the detector to eliminate the static electricity;
9
）
You may mark the position where the object is found; If the object’s edge
or central point is detected, mark the above position at the mark hole (A);
10
）
The detector is designed with temperature monitor unit. Constant
temperature inside the detector can ensure accurate detection; if alarm
icon 11
）
is displayed, it indicates the temperature is out of working range
or there is great difference in temperature; Turn off the detector and let it
restore normal temperature, and then turn it on again.
Maintenance
1
）
Keep the detector clean and dry all the time to ensure accurate detection
and safe operation;
2
）
Don’t put the detector into water or other liquids, use dry and soft cloth to
wipe up, any detergent or solvent is not allowed;
3
）
Don’t stick any label or mark on the detecting areas, front and back,
especially metal nameplate;
4
）
Don’t remove the nonskid mat on the back side.
Warranty
1
）
If the detector is unable to turn on or work in normal, please return it in
attached protective jacket to the dealer or factory for repair service;
2
）
Any damage arising from dismantlement without permit, improper
keeping or wrong operation, and the conditions of warranty paper alteration
or no sales paper, shall be out of the warranty;
3
）
Please observe the above provisions and we shall offer one-year product
warranty.
