Forclaz WT Trek 900

Our walkie-talkies are compatible with all types of rechargeable NimH 1.2V AAA batteries. In case of an emergency, you can also use 1.5V alkaline batteries, but be careful not to mix the two types of batteries and never try to recharge alkaline batteries in your walkie-talkie. This could cause damage and is not taken into account in our commercial guarantee (abnormal use of the product).

The BGB 500, WT TREK 500 and 900 walkie-talkies are rechargeable by USB. They recharge for batteries when they are connected to a USB power supply via the cable provided. You can therefore connect them to any charger (Car, Solar Panel, Computer, etc...) as long as this charger is USB compatible.

The power port of our following walkie-talkies:- ONCHANNEL 510 (ref: 8335339)- BGB 500 (ref: 8494241)- WT TREK 500 (ref: 8560563)- WT TREK 900 (ref: 8560564)are using MicroUSB standard. You can therefore use your own cable to recharge as long as it is MicroUSB comptatible.

Basically, when a subchannel is selected, a radio signal is added to the communication as long as you are transmitting. Any walkie-talkie listening to the same channel AND the same subchannel can then hear and communicate with you.

These acronyms correspond to two coding techniques for communication subchannels.- In CTCSS, the key is Analog (inaudible sound signal) and offers 38 combinations- In DCS, the key is digital (binary signal) and offers 83 combinationsThese are therefore two categories of perfectly independent subchannels.

As explained above, no. Indeed, in DCS, the walkie-talkie are not able to communicate with a CTCSS coding key and vice versa.

Walkie-talkies are so-called "free" radio transmitter / receiver devices. The frequencies are therefore standardized and numbered in Channels and subchannels). If you use a channel (from 1 to 8 for the WT TREK 500 or from 1 to 16 for the WT TREK 900, you can listen and communicate with other people.

When no sub-channel is programmed, your walkie-talkie does not try to decode the key of users who have selected a sub-channel (DCS or CTCSS). You are therefore able to listen to any user of the same channel, whatever its subchannel.Please note: as you do not have an activated sub-channel, you cannot speak to them.

The use of your walkie-talkies is regulated, you are free to use them in all countries of the European Union but also in Russia, Morocco, Tunisia, Turkey, Ukraine, Great Britain and Singapore. You are not allowed to use them in other countries.

Your walkie-talkies are PMR446 (Private Mobile Radio). They transmit on the 446Mhz frequency band. The use of this frequency band is free and usable without any license or authorization.

No, it is not possible to have several walkie-talkies transmitting simultaneously on the same frequency. The technology is called "Half Duplex", when you start a communication, the walkie-talkie uses the frequency to transmit the message and blocks its use by other devices. It is then necessary to wait for the end of the communication and the release of the frequency to be able to answer it.However, it is possible to have several transmitters simultaneously on different frequencies.

To simplify the use of the DCS and CTCSS subchannels, some manufacturers have "added" the 38 CTCSS subchannels (see explanation above) and the 83 DCS codes, which gives 121 subchannel keys.When this is the case, it must be considered that channels 1 to 38 correspond to a subchannel 1 to 38 in CTCSS and that channels 39 to 121 correspond to channels 1 to 83 in DCS.Ex: channel 105 of this type of Walkie-Talkie corresponds to the DCS subchannel n ° 67 of your DECATHLON walkie-talkie.
