BELL:
sound is first activated by passing the reed switch trigger. After the bell has rung a few times,
it may be triggered off by passing the reed switch over the magnet again. The bell will turn off at the
end of a ring.
GENERAL OPERATING INFORMATION:
VOLUME ADJUSTMENT:
should be set as desired for your application. Please remember that the
amplifier can produce more power than a small speaker can handle and that the sound will be
louder if the speaker is properly enclosed and baffled. If you are using batteries, the louder the
volume the shorter the battery life.
NOTCH ADJUSTMENT: this control adjusts the sensitivity range for the brake release to occur. Full
clockwise will produce a brake release at approximately 1.5 volts to the track / motor. Rotate the
control CCW to increase the voltage required. Gauge 1 and other operators using higher motor
voltages will probably want to set this control full CCW.
NOTE: The speaker impedance should be kept near or above 8
ohms, therefore four 8 ohm speakers in a series/parallel
configuration is acceptable since it yields 8 ohms total
impedance. If you care to use two 8 ohm speakers you must
place them in SERIES.
