1. OPERATIONS
1.1. General Operation
To prepare the unit for operation:
1) Review the control module in Figure 1.1-1 below.
2) Set the POWER switch to OFF by moving switch away from the operator.
3) Set the VOLUME to the lowest setting by turning knob counter clockwise.
4) Connect the microphone cable.
5) Turn the POWER switch to ON by moving switch towards the operator.
6) Turn the VOLUME control up to the desired level by turning the knob clockwise.
The Control Module is now ready to transmit recorded or live voice messages.

1.2. HyperSpike®Operating Modes
The AHDi gives the operator the ability to broadcast messages and tones. The message or tone is
selected from the control module by pressing the CHANNEL button. The channel selected is
shown in the numeric display on the control module. Figure 1.2-1 below defines the HyperSpike®
operating mode.

1.3. Microphone Operations
The dynamic microphone responds to the volume level of the voice. The louder the operator
speaks, the louder the microphone output will be. The microphone will override all pre-recorded
messages and the alert tone.
To broadcast a message using the microphone, press the CHANNEL selector button on the
control module until the display reads 0. Place the microphone close to your mouth. A good rule of
thumb is to have the rubber spacer against your top lip. Press the microphone PTT and speak
directly into the microphone, firmly and clearly. To increase the volume of the message, turn the
VOLUME knob clockwise.
CAUTION:
Audio feedback may occur when using a live microphone,
resulting in equipment damage.
Always operate the microphone directly behind the AHDi

1.4. Selecting the Alert Tone
The AHDi alert tone is used to get attention, provide warnings,
etc. To broadcast the alert tone, press the CHANNEL selector
button on the control module until the display reads 1. Press the
TRIGGER button as shown in Figure 1.4-1. To increase the
volume of the message, turn the VOLUME knob clockwise. The
alert tone will broadcast as long as the TRIGGER button is
depressed.
1.5. Selecting a Pre-Recorded Message
To select a pre-recorded message, press the CHANNEL selector on the control module until the
display reads a number between 2-9. Each press of the CHANNEL button will index the display to the
next message in the rotation of messages.
Once your desired message is selected, hold down the TRIGGER button to broadcast. To increase the
broadcast volume, turn the VOLUME knob clockwise. The message will broadcast as long as the
TRIGGER button is depressed.
1.6. Disable Ring
The AHDi is configured with a DISABLE ring or kill
switch. See Figure 1.6-1. When the DISABLE ring is
pulled out from the control module, the disable switch
is activated to quickly terminate power to the AHDi
speaker thus immediately preventing all audio
messages & alert tones from being broadcast. As a
safety precaution, the DISABLE ring may be tethered
to the operator for use during crowd control scenarios.
When the DISABLE ring is pulled out from the control
module, the numeric display will show rotating bars to indicate the disengagement. To reactivate,
simply reinsert the DISABLE ring into the control module. The power will be restored to the
speakers and the unit will operate as normal.
1.7. Charging the Battery
When the display shows a blinking “L”, the AHDi NiMH battery packs needs re-charging. Before
charging the AHDi, ensure that the POWER switch is in the OFF position. Using the battery
charger supplied with the AHDi, connect the Amphenol connector to the control module battery
connector shown in Figure 1.7-1. Connect the two-prong connector to a power outlet with a
voltage between 100 – 240 VAC. The AHDi battery pack will automatically begin charging.
The charger is equipped with an LED charging indicator. Figure 1.7-2 provides guidance on the
charging status of the AHDi battery pack.

1.8. Loading Pre-Recorded Messages
Up to eight custom pre-recorded messages can be up-loaded to the AHDi. The pre-recorded
messages are stored on a standard SD memory card which is located inside the control module.
Custom messages can be created and stored on the AHDi removable SD card.
Once a custom message has been created, the following directions provide steps needed to load
the new message to the AHDi.
1) Using a Phillips screwdriver, remove the cover of the
control module by removing the four Phillips screws
as shown in Figure 1.8-1.
2) Referring to Figure 1.8-2, locate and remove the SD
card from its holder by carefully sliding the SD card
from its holder.
3) Insert the SD card into any SD slot in a Windows-
based computer that is already powered up.
4) Left-click on the START icon (usually located in the
bottom left corner of the computer screen) then left-
click on COMPUTER.
5) Double left-click on the SD card icon to open window.
6) Left-click on the START icon again and then left-click on COMPUTER.
7) Locate the custom message where it was stored.
NOTE: Messages to be loaded into the AHDi must be a .wav file and named
“wave” using the following format:
waveN.wav where N= any number from 2-9
Each number will correspond to the number displayed on the control module
NOTE: If using a replacement SD memory card, do not use the mini-SD cards
with adapters. Using a mini-SD card with adapter will increase the risk of the
pre-recorded messages not playing properly.

8) Right-click on the message. Drag and drop the message to the SD card window.
9) Repeat steps 6-8 to load multiple messages.
10) Insert SD card back into the card holder in the control module. Figure 1.8-3 shows the proper
orientation of the SD card.
11) Replace cover and re-insert screws. Hand-tighten screws.

2. TROUBLESHOOTING
Malfunctions that might occur during operation of the equipment are as follows:
2.1. No Sound from Microphone
1) Ensure the microphone connector is making a secure connection to the control module.
2) Ensure speaker connector is securely connected to the control module.
3) Ensure channel 0 is displayed on the control module display and the VOLUME knob is set
above the minimum level.
4) Verify the speaker is functional by:
a. Select CHANNEL 1 to broadcast the Alert Tone.
b. At a low volume setting, press the TRIGGER switch and confirm the Alert Tone is
being emitted.
c. If the Alert Tone can be heard, the microphone needs to be replaced.
d. If Alert Tone is not emitted, the AHDi is not functioning and needs to be repaired.
See Section 3.0 for service information.
2.2. Pre-Recorded Messages not Broadcasting
1) Ensure the CHANNEL selector is set on a channel from 2-9.
2) If using custom messages, ensure that the pre-recorded messages are a .wav format.
a. Using a Phillips screwdriver, remove the cover of the control module by removing
the four Phillips screws as shown in Figure 1.8-1.
b. Referring to Figure 1.8-2, locate and remove the SD card from its holder by carefully
sliding the SD card.
c. Insert the SD card into a computer and verify the file extensions of the pre-recorded
messages are .wav and are labeled according to Section 1.8.
d. Re-insert the SD card into its holder, ensuring the card is secure. See Figure 1.8-3
SD Card Orientation.
e. Replace the control module cover.
3) Verify the SD memory card is securely inserted into the SD holder:
a. Using a Phillips screwdriver, remove the cover of the control module by removing
the four Phillips screws as shown in 1.8-1.
b. Referring to 1.8-2, locate and remove the SD card from its holder by carefully sliding
the SD card.
c. Re-insert the SD card into its holder, ensuring the card is secure. See Figure 1.8-3
SD Card Orientation.
d. Replace the control module cover.
e. If the pre-recorded message still does not play, either the SD card or the AHDi is not
functioning correctly.
f. To determine if the SD card is bad, load a new pre-recorded message on a new SD
card following the steps outlined in Section 1.8.
5) If the pre-recorded message still is not emitted from the AHDi, the unit is not functioning
and needs repair. See Section 3.0 for service information.
