Frequently asked questions for the Moby-Kid water alarm system:

01. How will I know, when the battery of the wristband with sensor is dead?
If the battery is dead, the base station will not recognize the wristband and an alarm will be generated within 10 seconds of startup.
02. How will I know, when the battery of the wristband with sensor is about to die?
If the battery power on the wristband with sensor becomes too low during operation, the receiver triggers an audible and visual alarm.
03. Can I change the battery of the wristband with sensor?
Yes. It is a common flat battery (3V type CR 2032), which can be changed with the supplied screwdriver. However, we recommend having the battery replaced by a specialist, so that an absolute watertightness can continue to be ensured.
04. How long does it take until I need to change the batteries of the strap and base station during normal use?
A battery change depends on the hours of use of the device. As soon as the voltage of the battery drops slightly, the base station stops connecting to the wristband and requires a battery change. We recommend using a new battery at the beginning of each season. For a bathing season, the voltage of the battery usually stops. Provided the battery has not been on the shelves for several years.
05. Should replacement batteries for the base station be taken on vacation?
You should always have a spare battery with you in case of a voltage drop of the used Battery to be able to react quickly. A fresh set of batteries will last for 6 months. The base station can be operated with these batteries (AA-Mignon), which are also available in every resort, should they become empty. In addition, the base station can be operated with the supplied power plug.
06. How is the bracelet attached to the wrist?
The bracelet can be easily adapted to the size of the wrist. This is usually done once per bathing season. Then it can be easily removed and put on with a quick-release fastener in just a few seconds.
07. What is the range between transmitter (wristband) and receiver (base station)?
The maximum range in the open area is 50 meters. This means there is visual contact from the base station (receiver) to the transmitter (wristband).
08. Can you turn off the transmitter (bracelet) when not in use?
No, but the bracelet automatically shuts off after 12 hours. After this time or when it is used again, it must be reactivated by simultaneously touching the metal points.
09. What happens when the bracelet leaves the area of transmission?
Since the permanent connection between receiver (base station) and transmitter (bracelet) is queried, we trigger a visual and audible alarm at the base station if this connection is lost.
10. Do I have to activate the transmitter (bracelet) with the metal fork every time to put the system into operation?
Yes, if the wristband has not been connected to the base station for more than 12 hours, it must be reactivated. You can also touch the metal points of the bracelet with a wet or damp finger to activate it. This feature really makes sense, as it significantly extends battery life.
11. I have a saltwater pool. Can the unit be used as well?
Yes, the bracelet (transmitter) is freshwater and seawater suitable.
12. Can I have my child play with the bracelet in the sandbox?
Yes, the bracelet is very resistant to dirt and a closed unit.
13. Can I also use commercially available batteries in the base station?
Yes. Insert 5 pieces 1.5V type LR6 / AM3 / AA. Do not use rechargeable batteries.
14. I have three children. So I need three sets?
No, they can operate three bracelets on a base station. A red transmitter bracelet (whale) is included in the set. Just order a green and blue bracelet.
15. Can I take the device on vacation on the sandy beach?
Yes, but protect the base station by packing it in the included protective bag.
16. At what frequency does the device send?
All Moby-Kid water systems send on the same frequency (433 Mhz). In addition, there is still a coding, which differs on information, which are sent along with the signal, the different bracelets.
17. What happens when my child puts the transmitter in his mouth?
The Moby Kid has been tested for the following chemicals:
– Cadmium, EN112 – Dimtyl fumarate – Saliva and sweat simulant, DIN 53160 – Plasticizer migration, DIN EN 71-9 – Plasticizer law, EPA M 1625 – Solvent migration, DIN EN 71-9 – Monomer migration, DIN EN 71-9 – Metal migration, DIN EN 71-3 – R OHS – PAK, ZEK 01-08. In summary it can be stated that the product is “free” of plasticizers and PAHs, where “free” refers to limit values, which means in concrete terms that the measured values ​​are below the limit values.
18. How loud is the alarm?
Maximum allowed are 110db. Our set uses for the alarm maximum 100 db in order to have some more buffer to the limit.
19. Can it be ruled out that there will be no child labor or human rights violations in the production of the Moby Kids?
Child labor can be excluded as the company that produces the product is certified BSCI (
20. What maximum salt concentration can the bracelet be exposed to?
The device is seawater suitable. It was tested in seawater. The seawater has an average salinity of 3.5% by weight.
21. Which protection class does the device conform to? IP XX?
The whale is 3 bar water resistant which means that it can withstand water pressure up to 30 meters. The bar specification can not be converted directly into IP classes. The closest would be the IP X8 class.
22. Are there any long-term or long-term experiences with this device that are representative?
Real long-term tests are not available. But last year we sold 8000 pieces of this device and only 3 complained. They claimed that the Moby battery was empty. But apparently there are often failures with the batteries, as far as the durability is concerned. That’s why there is usually no guarantee for batteries. In summary, it can be said that there is no problem with this device.
23. Why are there different codes and what are they for?
There are two different radio frequencies in the Moby Kid, so that two nearby devices do not interfere with each other. Short explanation for a repeat order: If the included red whale (transmitter) is used and a second whale (transmitter) wants to be bought, the customer orders either a blue or a green whale (transmitter). All used whales (transmitters) must have the same code, but different colors! To do this, the customer must read the code from the back of the existing whale or the CODE attached to the receiver and indicate this CODE (either 01 or 02) when ordering.
