UNIT WILL NOT POWER UP ON BATTERIES
Verify batteries (quantity 4, size AA) are fresh and that they are
placed in the battery holder in the correct direction, matching the
polarity shown on the battery holder, and that they are properly
seated. For Intrinsically Safe approved units the batteries are
required to be DURACELL MN1500 type.
If fresh batteries are installed and properly seated into the battery
holder and does not solve the problem, consult the factory.
To isolate the battery circuit, power the unit via the USB cable
powered from either the power supply or the port of a PC or
power supply. Continue on to the following section if the unit still
won’t power up:
UNIT WILL NOT POWER UP VIA USB CONNECTOR
WALL SUPPLY
Ensure that the wall supply is inserted all the way into the wall
socket
Verify that that the AC wall socket is of the proper AC voltage for
the wall supply
Verify that the wall supply is working properly by trying another
wall supply if available or power another USB device.
USB PORT
Plug the PTE-2 into the USB port of a PC. If the unit fails to power
up either the USB port is faulty, the cable is bad, or the HHC has
failed. Consult the factory.
UNIT WILL NOT COMMUNICATE TO A PC via USB cable
Ensure the connector being used to connect to the HHC is a
“Micro B” connector and that the connector used to connect to
the PC port is a standard USB “A” connector.
Ensure both connectors are firmly seated into their respective
female sockets at the HHC and the PC
When plugging the HHC into the PC listen for the “enumeration”
sound coming from the PC , if there isn’t an enumeration sound
either the PC port is faulty or there is a failure inside the HHC. Try
another USB port on the PC, if using a PC with both front and
rear USB ports try both the front and the rear ports
Look for the USB trident icon on the HHC display, if it is there
then the USB system has been properly enumerated
If communication to the PC is still faulty refer to the manual for
the proper set up of all drivers and software on the PC.
If issues still persist, consult the factory
