Tip: The SOS function


Safety is an essential factor to be taken into account when engaging in outdoor sports which sometimes present us with difficult or even extreme and hostile conditions. The phone has become an additional safety device for quickly calling for help.

CROSSCALL has decided to equip its TREKKER-M1 smartphone with a user-definable button that will provide access to an SOS* function.

It enables you:

  • To send a predefined emergency message or GPS coordinates to one or more contacts chosen in advance. To enter your GPS position, a real time-saver for the rescue services.
  • To make an emergency call to one or more contacts chosen in advance.
  • To cause the flash behind the device to blink, for rapid location.
  • To put your phone into loudspeaker mode, if you are unable to hold your phone for any length of time for instance.
  • To be located via the networks and to record the emergency call.

Follow the manual!

*The SOS function must not under any circumstances be regarded as an equivalent alternative to emergency calls to the authorities.

All the explanations have been provided with the CROSSCALL TREKKER-M1.


  • Go to «Settings» on your CROSSCALL.
  • Click on «Buttons» then in the «Programmable Button» section, select«SOS» pressing on the activate icon.
  • Accept the «Terms and Conditions».
  • You are then offered several options for managing your emergency call: «Recipient(s) of the emergency SMS» or «Recipient(s) of the emergency call».
  • In both cases: click on the 3 points at the top right corner of the screen. Select «Add an item». You will then be asked to enter the recipient’s number and the content of the SMS. Under the option «Add a contact» you can choose any person(s) you want to contact in the event of an emergency.
  • Under «Settings», you can also choose several options: «Location via networks», «flashing LED» in order to be located quickly, the «loudspeaker» mode and «Recording of the call».

CROSSCALL provides you with some additional advice for better managing your emergency call after protecting the victim(s):

  • Call the relevant rescue services: 112 or 15 (EMERGENCY MEDICAL SERVICES), 18 (FIRE BRIGADE), 17 (LAW ENFORCEMENT). If you dial the wrong number, your alert message will be repeated to the appropriate service.**
  • The emergency services will know nothing at all about the actual situation; they will ask you questions to get a better idea of what is wrong. Try to be as precise as possible. Speak calmly and clearly, ideally giving details in this order:
  1. Who you are.
  2. Explain where you are and how the accident site can be reached.
  3. State the nature of the accident.
  4. Describe the number and apparent state of the victims.
  5. Describe what you have witnessed, if possible: the number of victims, their sex and approximate age, their apparent state (bleeding, speaking, breathing …), their position (standing, sitting, lying on their back…), any movements they are able to make.
  • State whether there are any ongoing risks.
  • Do not be the first to hang up. Always wait for the emergency services to give you instructions.

Finally, you can also get first aid training from many emergency bodies, the Red Cross being the most well known.

**You can also enter the ski area number if you are on holiday engaging in winter sports or your local PGHM (High Mountain Police) details if you are going up into the mountains.
