Battery Indicator
After switching the device on the battery charge status is indicated by a sequence of short beeps:
5x Beep means that the battery is charged 95% or more.
4x Beep means that the battery is charged 75% or more.
3x Beep means that the battery is charged 55% or more.
2x Beep means that the battery is charged 35% or more.
1x Beep means that the battery is charged 15% or more.
When the battery is less than 15% charged you will hear a constant beep for one second after
switching the device on.
After indicating the battery charge XC Tracer Mini V
’s GPS now searches for a fix. A
beep-beep-
beeeeeep indicates that the device is now ready for flight.
Energy Management
Normally the energy of the solar cell is sufficient to power the XC Tracer Mini V and to charge the
lithium polymer battery during a flight. However, it is possible that due to unfavourable conditions
such as mounting the vario in the pilot's shadow, low sun position, cloudy sky etc., not enough
energy is supplied by the solar cell to operate the variometer and charge the battery at the same
time. In this case, the battery may slowly discharge during the flight. During the next flight it can be
different again and the energy is sufficient to operate the vario and recharge the battery at the
same time. After landing the vario should be switched off immediately to save energy.
Should it ever be necessary you can charge XC Tracer Mini V using an USB-C cable. It takes
approximately 3 hours to fully charge the battery so it's best to leave it charging overnight.
WARNING: attempting to charge your XC Tracer Mini V by placing it in hot sunshine when not flying
may result in it overheating and damaging the battery any other components!
WARNING: If necessary, charge the battery with the USB cable on the PC or on a 5V charger. Only
a 5V connection / charger may be used, do not use Fast Charge / Quick Charge / Super Charge
/ Turbo Power or whatever. If a voltage higher than 5V is used while charging, the electronics will
be destroyed.
We accept no responsibility for damage which occurs when not using the correct voltage for
charging!
Automatic Switch-Off
The automatic switch off is disabled on XC Tracer Mini V. The vario will run as long as the voltage of
the battery does not drop below 3.3V. (NB. The log file is written to the SD card before the device
turns off.
So you will always to have to switch off the vario yourself after landing!
