Purpose AQUAPHON is a system for the acoustic location of water leaks and water pipes. The AQUAPHON system can be used for: ● Leak detection ● Pipe location Note: All descriptions in these operating instructions refer to the system as delivered (factory settings). The operating instructions apply to the A 200 receiver with firmware version 2.x and higher. The manufacturer reserves the right to make changes.
General safety information This product was manufactured in keeping with all binding legal and safety regulations. It corresponds to the state-of-the-art and conforms to EC requirements. The product is safe to operate when used in accordance with the instructions provided. However, if you handle the product improperly or not as intend- ed, the product may present a risk to persons and property.
AQUAPHON system General information about the system 2.1.1 Communication The components of the AQUAPHON system communicate by bidirectional SDR (SDR: Sewerin Digital Radio). Wireless com- munication allows the user considerable freedom of movement. The sound quality of the acoustic playback is not affected by swinging cables. 2.1.2 Hearing protection The AQUAPHON system protects the user's hearing against sudden, loud interference noise.
● What is to be located? The purpose determines the choice of application. ● Where is it to be located? Conditions on the ground determine the choice of contact point. 2.1.3.1 Switch-on mode The receiver always automatically determines the switch-on mode.
The user starts by selecting the suitable components. Compo- nents that need to be connected mechanically are connected by the user. The user then switches on the components before switching on the receiver last. The receiver automatically recog- nises the components as it is switched on. With Direct startup, the system is ready to use as soon as the receiver is switched on.
System components 2.2.1 Overview The AQUAPHON is a modular system. The main system com- ponents are as follows: ● A 200 receiver ● F8 wireless headphones ● TS 200 carrying rod The carrying rod is required when using the following micro- phones: − BM 200 ground microphone − BM 230 ground microphone (with tripod) −...
Devices with position determination link the measurement data with the geographical coordinates (e.g. GPS) of the measuring location. Receivers with position determination module are identified by a sticker. 2.2.2.2 Setup Overviews with the names of all the parts of the receiver can be found inside the front cover (fig. 1 and fig. 2).

Information about the automatic brightness setting can be found in section 4.5.3 on page 54. ON/OFF key The ON/OFF key has the following functions: ●...
The receiver is usually carried in front of the body so that the user looks diagonally down at the touch screen. SEWERIN recommends: Use a carrying system for locating op- erations. The carrying system prevents you from tiring during work. It also reduces the possibility of radio interference. Ra- dio interference can occur if the user accidentally covers certain components in the receiver.
2.2.2.6 Automatic power off The power supply to the receiver is designed in such a way that a fully charged battery will allow one full day's work without in- terruption. However, it is still recommended to conserve energy whilst working. The receiver therefore offers the following automatic power-off options: ●...
