5 Storage and Transport
In order to avoid unwanted radio transmissions and prevent battery depletion, the ALPHA
must be set to sleep mode for storage and transportation.
In sleep mode, the ALPHA will listen on the Gutermann radio every 30 seconds, but not
transmit. The modem will also stay switched off.
In order to enter sleep mode, open the ALPHA, press the button at the top and keep it
pressed for 2 seconds. The LED will confirm entering sleep mode with 5 red flashes.
The ALPHA will enter sleep mode on its own if over the course of two days there is no power
supply connected and no SIM card inserted.
