==GPS Sleep mode==
{{{model|FM36YX}}} is able to go to GPS sleep mode if such mode is enabled.<br/>Sleep mode timeout starts counting when device is in STOP mode. After timeout is reached and all conditions for GPS sleep mode are met, device goes to sleep mode. While in GPS sleep mode, {{{model|FM36YX}}} turns GPS module off and is still making new periodic records. As a result power usage decreases, in turn saving vehicle battery.<br/>{{{model|FM36YX}}} will enter GPS sleep mode if ALL of these conditions are met:
{{{model|FM36YX}}} is able to go to GPS sleep mode if such mode is enabled.<br/> Sleep mode timeout starts counting when device is in STOP mode. After timeout is reached and all conditions for GPS sleep mode are met, device goes to sleep mode. While in GPS sleep mode, {{{model|FM36YX}}} sets GNSS receiver to sleep mode and it isn’t making periodic records (only event records is being recorded with last known coordinate and sent to AVL server). As a result power usage decreases allowing saving vehicle battery.

* {{{model|FM36YX}}} has to be configured to work in GPS Sleep mode and sleep timeout is reached;

While in deep sleep mode, {{{model|FM36YX}}} sets GNSS receiver to sleep mode and turns off GSM/GPRS module (it is not possible to wake up device via SMS). Despite records with last known coordinate being saved and sent to AVL server (GSM/GPRS module is turned on to send data and then it is turned off), power usage is decreased to save vehicle's battery. Note, that power saving depends on two configurable parameters: send period and minimum record saving period in "X on Stop Mode". When records are sent successfully in deep sleep mode, open link timeout counter will be skipped and {{{model|FM36YX}}} will enter deep sleep mode immediately.<br/>Because a lot of functions are disabled in deep sleep mode 13 I/O elements are disabled from records that are generated in this mode: GSM Signal, GNSS Status, GNSS PDOP, GNSS HDOP, Speed, GSM CellID, GSM Area Code, Fuel rate GPS, Active GSM Operator, Trip Odometer, Total Odometer, Fuel Used GPS and ICCID.
While in deep sleep mode, {{{model|FM36YX}}} sets GNSS receiver to sleep mode and turns off GSM/GPRS/3G module (it is not possible to wake up device via SMS). Despite records with last known coordinate being saved and sent to AVL server (GSM/GPRS/3G module is turned on to send data and after that it is turned off again), power usage is decreased to save vehicle’s battery. Note, that power saving depends on two configurable parameters: send period and min. record saving period.
