ANT button (silver):
Threaded hole on the top side of the receiver is the terminal for the whip antenna. Two threaded
holes on the bottom side of the receiver (35 mm spacing) are for mounting the compass holder.

fully charged,
Charging: Use the N40 charger. The yellow light indicates charging in progress, it goes out at the end
of charging (the charger terminates charging automatically). Keep the receiver charged (i.e. charge it
after the activity) - you lenghten the accumulator lifespan.
Note: when the accumulator is fully charged, the charger does not even start charging. As new
accumulators have higher voltage, you have to discharge it at least by 40% or so. Conclusion:
after the competition connect the charger. If yellow indicator in the connector turns on, let the
receiver being charged, otherwise disconnect the charger and try next time (there is certainly
enough energy for several competitions in the accumulator).
