1) Cell phones and life saving whistles
When using a mobile phone to call for help, you should use messages and turn the phone on t to send and receive messages every half hour or an hour, which can greatly save the phone power. When using lifesaving whistle, you ought to comply with the international standard and send a distress signal per minute six loud whistle practices. Besides, you can also obey the international general "SOS" distress turn signals: send again and again with three long signals and three short signals.
2) Clothing and flashlights
You can also use a flashlight and clothing to send a signal to the outside world when there is no lifesaving whistle. Use clothing to send signals to the outside world with the circle similar to "8" in the air, which is also the international standard way of distress. At night, a flashlight should be used to send a signal. Flash for six times because it is the international conventions.
3) The fire
You can find branches or other combustibles in the wild, light a pile or a few, and add some wet branches or grass to the fire to raise a lot of smoke.
4) Put up some logos
To grip rescue workers, we can also use branches, rocks, or clothes to put out signals of "SOS" or "HELP" as large as possible and put something brightly-colored such as bright red in a prominent location.
Experts remind
No matter how you ask for help from the outside world, you should always adhere to the principle that all rescue operations can’t be carried out until the rescue workers reach you.
