The Screecher™ is a bird control (scarring) payload that has been designed for use with our AeroDrone systems. It is powered by a 12V DC source and operates completely independent of the drone. This also allows Screecher to be used on other types of drones as well.

Hardware Overview

Below is a hardware overview diagram that shows all the major components of the Screecher payload.

Hardware Specifications

Size (W x L x H)130 x 110 x 110mm
Weight304g (excl. power cable)
Power Input12V DC

Power Switch

The power switch enables the unit to operate. It is located in the
upper right hand corner of the control panel (as shown below).

Slide the switch to the “ON” position to start the unit and the “OFF” position to turn it off.

CAUTION: Please check the position of the volume dial as having it turned all the way up and switching the unit on may cause pain or damage to your ears
Please leave the unit off for 30 seconds before turning it back on to allow the electronics to completely reset.

The volume dial is located on the upper left-hand side of the control panel (as shown below).

Turning the dial anti-clockwise will reduce sound output level while rotating the dial clockwise will increase the sound output level.

CAUTION: Take care when turning the dial since the unit may be in a temporary inactive state (ie. delay) when the dial is rotated. It could then reactivate at a high sound level causing pain or damage to your ears.

To program your Screecher Bird Control Payload you will need a small blade screwdriver, toothpick, or some other small, rigid object to toggle the switches in the switch array. The switch array is located on the right-hand side of the control panel (on the back of the unit) as shown below.

A switch is ON when switched towards the right-hand side and OFF when towards the left-hand side. This is indicated with “ON”, “OFF” labels underneath the switch array.

Recording Setting Switches

The Recording Setting Switches (shown below) are the first eight switches in the switch array (labeled “1” to “8”). Each switch has a recording number to the right of it that corresponds to a different sound recording.

Mode Setting Switches

The Mode Setting Switches (shown below) set the various modes of operation, such as the amount of time between playing bird distress calls (the “Time-Off”), when the unit will operate (ie. day only, night only or 24 hours, AKA the “Schedule Time”), and whether the unit will operate in the random mode or normal mode.

Switch #Mode or Function
1 and 2Sets the “Time Off” Period
3 and 4Sets the “Schedule Time” Period
5Turns Random Mode ON or OFF

“Time-off” Switches

The two “Time-Off” switches are located just below the recording switches in the switch array. When the unit is set to one of the various Time-Off modes, the unit will delay a number of seconds or minutes between playing the recorded sounds.

PLEASE NOTE: The unit will play all of the selected recordings (either sequentially or non-sequentially, depending on the Random Mode) then it will go into the delay time.

The time the unit stays off depends on the Time-Off and Random Mode settings. If the unit is operating in Random Mode, the unit will delay anywhere from the minimum value to the maximum value for that Time-off setting. If the unit is not in Random Mode, it will only delay for the minimum amount of time.

To set the Time-Off period (or delay interval), use the following settings on switches 1 and 2 in the mode settings section of the switch array.

Schedule Time Switches

The two “Schedule Time” switches are located just under the “Time-Off” switches in the bottom switch array.

  • ‘Night Mode’ – operates the unit at night
  • ‘Day Mode’ – operates the unit during the day.
  • “24-Hour Mode” – operates the unit continuously, regardless of the time of day.
The photocell that senses sunlight and determines the “time-of-day” is susceptible to bright light. Take care not to have bright lights shining towards the unit since this can prevent the unit from operating properly.

To set the time period for the unit to operate set switches 3 and 4 in the Mode Function settings to the following:

Switch 3Switch 4Mode
ONOFFDay Mode
OFFON24-Hour Mode
ONONNight Mode
OR
OFFOFF

Random Mode Switch

The Random Mode Switch is the bottom switch in the switch array. The unit will randomly play the selected recordings in non-sequential order when operating in Random Mode. When the unit is not operating in the Random Mode, the unit will play the selected recordings in a sequential order. Random Mode is recommended to keep birds from adapting to a preset pattern of sounds.

To operate the unit in Random Mode, set switch 5 as follows:

Switch 5Mode
ONRandom Mode ON
OFFRandom Mode OFF

ProblemSolutions
  • Unit is switched ON, but no sound is being emitted.
  • Check power source.
  • Check volume setting.
  • Check at least one recording is set to ON.
  • Check “Schedule Time” setting.
  • Unit is switched ON but plays the same recording over and over.
  • Check recording settings and make sure more than one recording is set to ON.
  • Switch unit OFF for 30 seconds and then switch back ON.
  • Unit is not operating correctly in DAY or NIGHT mode.
  • Double check mode settings.
  • Make sure photocell is not obstructed.
  • Make sure no bright lights pointed at the unit are affecting the photocell.
  • Unit does not function properly when connected to 12V battery.
  • Check battery condition.
  • Check power wire condition.
