1. Preparing for use
1) Inspection method
Please follow the guidelines to keep the unit a normal state.
1. Confirm that an antenna cover is attached to an antenna exactly.
2. Confirm that battery is completely charged and it is locked well.
3. Prior to use, a steering wheel is put up and is adjusted to appropriate height and
confirm whether it is locked.
4. Confirm that a monitor is adjusted to an appropriate angle.
2) Antenna cover
When letting antenna part in contact with the ground and use it, burdens always hang over
the antenna part.
To prevent abrasion of the lower antenna by the contact, an electrostatic cover is attached
to an antenna.
When replacing a new antenna cover with the
worn antenna cover, off the screw.
Under no circumstances, do not operate it without
antenna cover. May cause irreparable damage to the
antenna housing.
When fitting a new cover, tighten screw by hand.
Do not overtighten.
Check antenna cover daily.
If any part of the cover is worn, it
should be replaced immediately.

2. Battery & charging
Battery pack is supplied.
Please make sure it is charged fully before first use. Failure to do so may considerably shorten
the life of the battery pack supplied.
Battery is contained in the battery compartment by pushing the locking pin down. To release
the lock, push the locking pin again, then, withdraw the battery pack.
Replace battery when battery life lasts less than 90 minutes after being fully
charged (atmospheric temperature 20℃)
Fitting/Removing the battery
Step 1
Make sure power is OFF.
Step 2
Keep battery terminal downward, insert it into the
battery compartment like in the left photo.
Step 3
Battery lock pin be down and fixed.
When taking battery out, down lock pin and release
the fix.
When charging the battery, use the supplied charging pod
and adaptor.
Do not use any other adaptor or charging system.
It could damage battery and result fire or injury.
When taking battery out, the power switch of the unit
should be off. When taking battery out with power on, it
causes the unit trouble.

Move the unit to reverse with the searching direction. Put cursor to the highly possible point of
service. By the icon (►◄) of the cursor center, the accurate position searching of service is
possible.
The estimated depth of service is displayed by tapping data panel. Maybe the object is missed
with weak reaction or hiding by the reaction of the strong circumference but by adjusting the
sensitivity, the object can be found. Be able to confirm the effect of the adjustment on a screen
immediately, operate can be done intuitively and quickly.
Note. The system will automatically reset sensitivity back to the default (center
point) position, each time the system is powered up, until then the last used
setting will remain in effect.

16. Chronos masking
Provides masking of the measurement data. Masking setting is replaced whenever tapping
Chronos masking. It is used when need to cutoff data depending on estimated depth or cutoff
neighboring service to the vertical direction.
As long as Chronos masking works, data is never lost even if how many times repeating each
setting. Able to perform repeatedly, even the beginner can find the rough estimated depth easily.

19. Depth estimation
1) Basic
The estimated depth function is the function that the depth of the indicator value is displayed
just to choose the data of the specific place with the cursor.
To start a depth estimated function, while choosing data with the cursor, please tap the data
Panel. In the upper part of the Chronos masking icon, the analyzed depth will be displayed.
This is the estimated depth only by the data which the cursor is put. (unit: Meter)
The precision of the estimated depth is ±0.1m (100mm). However, the precision is different
from the situation of the underground such as water content ratio, the quality of soil and the
state of the measurement data. When an estimated depth result becomes out of a range, the
symbol which indicates impossible of the depth measurement is displayed. (See P7)
By performing sensitivity adjustment by manual operation, the estimated depth may be
displayed. In this case, an error grows big in comparison with the initial setting and the
measurement accuracy becomes ±0.3m ~ 0.5m (300mm ~ 500mm).
2) Advanced
The receiving signal may be mixed because it is reflected at a more chaotic place including a
city area and the metropolis by the multi neighboring buried service.
To influence precision of the estimated depth most is when the buried service is neighboring
and it is located up and down.
In such situations, please use Chronos masking to ensure estimated depth. The multi buried
service is isolated by four masking levels. This work allows the compartmentation of the
neighboring buried service that located at up and down.
！ CAUTION
The analyzed depth result is an estimation.
Without
conclusive evidence by the further searching and visual
contact, please do not assume it as the confirmed depth. As
for the digging, please follow to the instruction rule of the
industry.
