Active brake
Active brake (AB) is a feature, which if activated, will stop the
motor after each shot (in semi-automatic mode) or when the
trigger is released (in full auto). This prevents the spring from
staying compressed and in case of replicas with high rate of
fire, eliminates possible double shot problem. On the other
hand, activation of the active brake always leads to increased
wear of motor brushes, as well as its faster heating. We
advise to turn AB off during the game if it is not necessary,
and to turn it on just to fire one shot in semiautomatic mode
at the end of the day, so that the spring remains
uncompressed during storage. Also, with AB deactivated the
piston will stop closer to the rear position, so the next shot
will be fired quicker.
In order to turn AB on or off, press and hold button on the
device for ca. 2 seconds. One long sound signal will mean that
AB has been turned on, three short signals will mean it is
disabled.

Li-Po protection
Batteries should never be discharged below certain level.
Perun AB has a low battery voltage warning feature for
lithium-polymer batteries (Li-Po). If activated, after the
battery has been discharged to a dangerously low level Perun
AB will signal that by short sound signals recurring every 30
seconds. Battery’s nominal voltage will be detected
automatically. To activate low battery voltage warning, press
and hold the button on the device.
Keep holding the button for ca. 4 seconds until second sound
signals are heard. First signals will be for the AB, as described
above, second will be for Li-Po protection. One long sound
signal will mean that protection is on, three short signals will
mean it is off. AB setting will be changed after this, so you will
have to restore previous AB setting.
