The battery may be charged by either connecting the NAV SD USB connector to the wall socket charger,
or to a powered USB port using the USB cable. USB connector can be found on the right side of the NAV
SD (see gure

).
1.1 Charging the Battery
Flymaster NAV SD has an advanced battery power management system, which gives the pilot accurate
information about the battery state, as well as the charging time and battery remaining time.
To charge the Flymaster NAV SD battery you may use the wall charger, the USB cable, or the car charger.
Original Flymaster accessories are recommended in order to avoid damage to the power management
system.
The Flymaster NAV SD has 2 charging modes, namely, Quick Charge and Slow charge. The charging
mode choice is automatic and based on the power source. Quick charge mode is activated when charging
with the wall charger or the car charger, while Slow Charge mode is activated when a USB cable connected
to a PC or MAC is used.
Charging, and battery status information is shown on both the power up screen and the Shutdown menu.
When the Flymaster NAV SD is connected to a power supply (wall charger or via USB cable), even with
the unit o, the instrument will show if it is being Slow or Fast charged. The time remaining to full charge
is also shown. This may not appear immediately when a power source is connected, since the instrument
requires some time to calculate the remaining charge time. A Slow charge is ok for topping up the battery
but not for fully charging. Use the wall or car charger to fully charge the instrument.
Note: The instrument will not charge when it is turned on and connected to a PC. The
instrument must be turned o in order to charge the battery using the PC USB port . This
behavior is deliberate to prevent overwhelming competition organizer's download hubs.
Note: Charging the instrument with high ambient temperatures should be avoided. Such
action can cause the battery to overheat and aect battery health.
1.2 NAV SD Keys
Four keys are used to interact with NAV SD (see Figure
1.2

ENTER key - S2, UP key - S3, and DOWN - S4. Each key has 2 functions depending whether the device
is in ight mode or in menu mode. Additionally the MENU key is used to power-up the NAV SD when it
is switched o.
