Note
•
If the HI-PRO 2 unit is connected to the PC via a USB hub, the hub must
be self-powered (have a separate power supply). This is to ensure that the USB
hub can deliver enough current for proper operation of the HI-PRO 2 unit.
3.3 Starting up HI-PRO 2
When the HI-PRO 2 Installation CD is installed, HI-PRO 2 powers on as soon as the
unit is connected to the PC and the PC is powered ON.
During power-up, the LEDs next to the connectors on the front panel will flash
once indicating that a brief self-test is in progress.
When the self-test is completed, only the power LED will light. If only the left LED
flashes, the self-test has failed and you should try powering on again. Should the
unit fail again, contact your local distributor.
The HI-PRO 2 connector LEDs will also light up when a hearing instrument is being
programmed, indicating which side is active.
The LED above the text ‘PC Com’ lights up to indicate communication with the PC.
Caution
•
Do not attempt to connect or disconnect a hearing instrument
while the connector LED is active! The LED indicates that the connector is act-
ive, and this might damage the hearing instrument.
Caution
• Even though the hearing instrument connectors on the front of the
HI-PRO 2 are galvanically insulated from the PC and mains earth, it is still pos-
sible to release an electrostatic discharge (ESD) to a connected hearing instru-
ment, and through the HI-PRO 2 to earth. An electrostatic discharge can be
very uncomfortable for the client because it feels like a minor "electric shock",
and can even produce loud pulses of noise. Cases of electrical damage to hear-
ing instruments have been reported. It is recommended to install the unit in
an environment that minimizes the amount of static electricity. For example,
anti-static carpeting is recommended.
3.4 Disconnecting HI-PRO 2 from the PC
HI-PRO 2 automatically powers off together with the PC, but if you wish to power
off the HI-PRO without powering off the PC, you can disconnect the USB cable from
