The device is designed to be mounted in a zone of limited access, which is inaccessible to the operator. All related devices must meet the requirements of EN 60950-1 standard. NTP server 1 and NTP Server 2 let the user select which NTP server (s) will be used to re-synchronize time. Low Power mode functionality was implemented to firmware from FMB.03.28.02.Rev.00. This functionality only works on devices that supports battery. It can only be active if device sleep mode is configured as Deep Sleep or Online Sleep. In other cases, low power mode is not allowed. CAUTION: RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS. LLS calibration - in this section you can calculate calibration values of Analog LLS sensors for AVL server - create a polynomial which is needed to convert sensor values to liters:

Engine RPM - if RPM from OBD II or CAN is higher than 0 - ignition is ON; if RPM from OBD II or CAN is equal to 0 - ignition is OFF; From 03.25.14 firmware the new time synchronization works by waiting a minute on startup to acquire fix and consequently synchronizes the time via GNSS. Periodic Wakeup – if value is greater than zero, device while being in Deep Sleep or Online Deep Sleep, will wake up after defined period for beacon collection. This is mainly should be used when Bluetooth is disabled in sleep.

The nominal voltage is +12 V DC. The allowed voltage range is +6..+30V DC. Ignition status is used in power management and the following functionalities: Eco/Green Driving, Excessive Idling, Fuel Consumption, Over Speeding, Towing Detection and Trip. Accelerometer - after the button is pressed, the device starts to capture accelerometer values for 1 second. Main calculations of separate HDOP/PDOP values of GPS, GLONASS, Galileo and BeiDou are made by GNSS modem. GNSS Modem already outputs average of HDOP/PDOP from 4 GNSS systems (Used satellites) with a formula below.

Do not disassemble the device. If the device is damaged, the power supply cables are not isolated or the isolation is damaged, DO NOT touch the device before unplugging the power supply. Calculated HDOP/PDOP value according to above parameters - (1.60 + 1.60 + 0 + 0) / 4 = 0.8 coefficient.Improved simultaneous DNS requests issue (DNS fails if requesting at same time). Do not affects FM3/FM4 with ext modem
