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.
