CHAPTER 7
Siren
The robot siren is operated by remote control from the Radio Control Transmitter. The siren
circuitry is located on the main circuit board. See the Main Circuit Board diagram, in the
Appendix, for the location of the siren volume, mode select and oscillation frequency adjust.
The
volume of the siren
is controlled by a trim pot on the main board. Turning the pot
clockwise will increase the volume of the siren. Turn the pot counterclockwise to decrease
volume. Three different sirens are available. Choose the siren you want by moving the jumper
located on the
siren mode select
. To control the oscillating speed, adjust the
siren frequency
trim pot
in the siren circuit. The siren mode select is set to the common siren for your robot. If
the siren mode select is changed, the siren frequency will very likely need to be adjusted.
NOTE:
The volume and oscillation are preset at the factory and do not need to be adjusted
unless you want a different volume level or oscillation speed.
