3 USING THE CONTROL BOX
3.1 Control box power supply
The LEADER Search is delivered with a lithium polymer battery pack which is inserted into the back
of the control box.
The battery pack is recharged SEPARATELY from the control box.
Charging can be carried out at between 0°C and 45°C (maximum temperature) using the supplied
charger.
During charging, a LED located on the charger provides the following indications:
▪Green: battery charged or battery not connected to the charger.
▪Red: battery charging.
During operations, if the battery pack is run down, the user can either use another battery pack
(supplied as an option), or the backup battery pack as a replacement for the initial battery pack.
The backup battery pack requires 10 AAA batteries (not provided).
The battery pack can ONLY be charged using the supplied charger block. It can be used with
100/240VAC - 50/60Hz
The international adapters can be used to recharge the battery pack on all US, Australian, European,
and UK power outlets.
Once the appliance is powered on, if the camera or at least one seismic sensor is turned on, an icon showing
the battery pack charge level remains displayed on the top right of the screen.

3.3 Using the sun shield
In bright light, the sun shield is used to place the screen in a dark area
to be able to see it better.
To hold the sun shield on the control box it must be correctly positioned
on the face on the forms designed to this effect. The red line shows
the position.
The wide elastics are used to ft it quickly and easily.
It is stored flat for easier transport. An elastic on its side is used to keep it flat and fix
it to the control box. By placing it on the screen face, it protects the screen when moving around
when the search device is not in use.

4 SEISMIC SEARCH MODE
4.1 Using the seismic sensor
To power on the wireless sensor, the push button must be pressed for at least 1 second. When the sensor
is powered on, the green push button LED lights:
•Slow flashing: no connection with the control box.
•Fixed: connection with the control box in progress.
•Fast flashing: connection with the control box
established.
•Very fast flashing: pairing sequence in progress (see
Pairing section).
To power off the sensor, the push button must be pressed for at least 1 second.
If the sensor does not connect with the control box, it powers off automatically
after 20 seconds.
To connect several wireless sensors, it is important to use the following powering
on sequence:
1. Power on the control box until the LEADER Search logo is displayed.
2. Press the sensor push button. When its LED flashes quickly the connection is complete
and the corresponding sensor bar chart appears on the control box screen.
3. Repeat step 2 for the next sensor.
Important: Do not power on all the sensors at the same time, but one after the other.
Wait for the powered on sensor to appear on the screen before powering on the next sensor.

15
4.2 Pairing the seismic sensor
To be recognised by a control box, the sensors must be paired to it. Initially the sensors are paired with
the control box they are delivered with in the factory.
However, each sensor can be used on any LEADER Search control box.
If you need to pair a sensor to another control box, follow the sequence described below:
1. Turn off the control box.
2. With the sensor powered off, press the push button for 15 seconds and then release it. The green
LED will flash very quickly and then go out at this stage the sensor is no longer paired to any control
box.
3. Turn on the sensor to be paired. The sensor's LED flashes very quickly again. If the LED
on the sensor to be paired does not flash quickly, repeat step 2.
4. Turn on the control box. The sensor will then carry out the pairing sequence for a few seconds
and then switch off automatically.
5. Switch the sensor back on. it is now recognised by the control box and its bar-chart format signal
appears on the screen.
A selector in the sensor battery compartment can be used to select the sensor number (n°1, n°2 or n°3).
The sensor number is memorised by the sensor during the pairing sequence. To make the sensor memorise
a new number, it should first be unpaired, the switch must be placed on the required sensor number,
and then the pairing sequence carried out.
Once paired, the sensor keeps the number assigned to it, even if the selector is mistakenly positioned
on another number.

4.3 Menu: Description of the Seismic mode functions
4.3.1 Seismic mode
The seismic menu appears when one or more seismic sensors are connected. The bar-charts are shown
for each connected sensor, with the maximum level carried over. By default the sensor sound gain is set
to 50%. The browser "▲" keys increase the gain for all sensors and the "▼" keys reduce it.
A headset icon placed under each bar graph indicates that the sensor is audible. It is MONO:
the sound can be heard in both ears.
The option to listen or not listen to a sensor is made using the keyboard keys located below each bar
chart. In the configuration below each sensor can be heard in both earphones on the headset.
There is a second listening mode
on the seismic menu: STEREO mode.
It is used to concentrate listening
to the sensors using the left or right ear.
This second mode can be accessed by
pressing the "Toggle" key. Once this
mode has been selected, the user can
listen to each sensor in the left or right
headset earpiece using the keyboard
keys located beneath each sensor
(or all the sensors at the same time).
This listening direction is shown by
an arrow pointing left when listening
in the left earpiece, and pointing right
for the right earpiece.
The tracer turns red on the sensor that detects the highest peak. If 2 sensors
detect the highest peak at the same time, then they will both be red. This tracer
is carried over onto the scale for easier readings.

4.3.2 FONCTIONS SELECTION
The menu button is used to access the different menus.
Up to five icons can then appear.The "▲" and "▼" browser keys are used to select the required
menu. Once the menu has been selected, pressing the validation key gives access to the menu.
Pressing the menu key again is used to exit the menu and return to the main screen.
The "filter high" function gives access to low-pass filter settings
and is used to remove sharp noises. Its cut-off power is used to remove
all frequencies above its setting threshold (Setting threshold: 600Hz
to 3000Hz).
The "filter low" function gives access to high-pass filter settings
and is used to remove bass noises. Its cut-off power is used to remove
all frequencies below its setting threshold (Setting threshold:
20 Hz to 300Hz).
The "com probe" function gives access to audio sensor use
and its settings. The icon is only displayed if the audio sensor
is connected to the LEADER SEARCH.
The "battery levels" icon gives access to the battery levels
on the connected wireless sensors. The icon is only displayed if at least
one wireless sensor is connected to the LEADER SEARCH.
The "brightness" function is used to set screen brightness.

18
4.3.3 Filter control function
The LEADER Search is equipped with two filters that are used to remove surrounding noise,
a"low-filter" and a "high-filter". The seismic sensors can detect vibrations from 20 to 3000Hz.
The filters are used to remove parasite noise that is inevitable during an intervention or caused by the weather.
By default the filters are not activated. The settings bar at the right of the screen is at the minimum.
The "▲" and "▼" navigation keys are used to increase or reduce the selected filter's cut-off frequency.
Filter use:
To eliminate parasite noise, increase the low filter cut-off frequency until the noise disappears from
the headset. If the noise can still be heard, reset the low filter to zero and repeat the operation using
the high filter. To exit filter settings, press the menu key.
4.3.4 Sensor battery level function
Once selected, the "battery level" battery function is used to view the “battery level”for each connected
wireless sensor. A six level scale clearly shows sensor autonomy. To exit the battery menu, press the menu
key.
Wireless sensor autonomy is about 8 hours and varies depending on the type of batteries used
(3 AAA batteries). The screen below shows 3 connected sensors.

19
Wireless connectivity
Wireless devices are subject to environmental constraints which affect their use.
A wireless desk telephone, for example, can have connection/reception difficulties. However it is not less
useful than a wired telephone!
Indeed, in some cases linked to the location itself, interferences can prevent the signal from being displayed
on searching device for a few seconds. It returns in a reasonable period to continue searching.
To make it right; Adopt the attitude of someone who is aware that the wireless equipment has certain usage
constraints and apply the following advice to your victim search equipment:
- Place the sensors in view of the control box: Avoid placing them in holes.
- Position yourself up high with the control box.
- Leave as much free space as possible between the control box and the sensors: Nobody between the box
and sensors; the human body creates a natural barrier; do not show your back to the sensors.
- Consider the weather: depending on humidity/electricity in the air/sun, wireless will work better or worse (eg:
A radio can emit further in good weather).
Despite these constraints, wireless technology unquestionably has operational advantages which overcome
them:
- Rapidity of movements in rubble (no trapped wires).
- Safety of sensor holder during moves (no imbalance due to trapped wire).
- Efficiency of the search operations (larger zone covered).
- Freedom of movement.
- 30m range on average, much broader than the length of wired sensors (8m in general).
Low battery display
A battery icon displays above the corresponding graph bar when the batteries of a sensor become low
(20% remaining power).
With a low battery level, it increases the risk of disconnections and reconnections. It is therefore recommended
that you replace the batteries with new ones.
Here, the 3 sensor batteries are low.
It is also possible to view the battery charge level by selecting “sensor battery” in the menu.
