Only fuses with the required rated current, voltage, and specified type must be used. Do not
repair fuses or short circuit fuse-holders. To do so could cause a shock or fire hazard.
Check for Boot Code Error:
If the H-ADCP gives a steady "beep" when power is applied, the ">" prompt appears on the screen, and a
"X" appears when additional breaks are sent, this may indicate that the boot code has been lost. This can
happen if you abort while downloading new firmware. Try downloading the firmware again.
