V．OPERATION：
1. Turn the power switch (10) to hear alert sound or vibrate, which means
that the power is turned on,.when the green light blinking, the detector
can be use. If the green light is not blinking, maybe the battery is broken,
or the battery can not be reused,when the yellow light on , please
recharge or replace the batteries with new。
2. sound, vibration change option: switch (10) for the third gear switch,
intermediate stops to turn off the power, docked one side of an audible
alarm, vibration alarm the other direction。
3. After the power is turned on, you can perform high sensitivity detection,
Scan the target with the Detection Area ,when metal be detected the red
light on and the alarm sound or vibration.
4. low sensitivity detection: If you need a low-sensitive detection (such as
in the vicinity reinforced of the ground to find a coin), you can hold
down the low sensitivity switch (9),then the sensitivity reduced to
about 1/5。
5. Charging: when the yellow light is on, It’s means the battery power is
low, please connect the charger. when the battery voltage reaches 9V,
green light (8) will light up when the green bright enough to prove ,that
the battery is fully charged. (Charging time depends on the specific
battery capacity, our factory standard battery is about 3 to 6 hours to
full)
