| L1 |
The LED L1 (Red colour) reflects the battery and
charger state:
- Continuously ON: charge process completed or interrupted
- 2 flashes: high current charging
- 1 flash: trickle charging
The LEDs flash briefly every 3-4 seconds.
The charge process is halted:
- When the CLARINET is running a profile
- When the battery is fully charged
- During CLARINET initialization (about 30s after power-on,
or loader op.)
Normal operating states is "continuously ON".
When the LED is continuously OFF it means the battery is flat

ID
(Coding wheel) |
Several Clarinet modules connected to the PC must
have a different ID's (from 1 to 7), set by the coding wheel.
After changing the value selected on the coding wheel the Clarinet
Loader must be executed. |

The Clarinet-Book detects if a suitable cable is connected
to one of the HD60 sockets:
- If so, only the relevant LED is turned on
- Otherwise, the 4 LEDs are all turned on.
An 'Error cable' message is displayed in the event file.

| Unit Power |
The Clarinet module connected
to the PC can be powered by :
- A set of batteries normally placed inside the module.
- The USB connection to the PC (or a HUB device).
- An external power supply unit.
When the CLARINET is only powered by USB
(bus-powered device), it is only trickle charged.
As the NiMH batteries can be deteriorated by overcharging,
a full charge process is only done if the battery is detected
low at initialization. To force a full-charge process, select
0 on the coding wheel and connect the external power adapter.
|
| Startup |
THe CLARINET is started up when
power is detected on USB bus during the PC power-on sequence,
or when a USB connector is plugged in.
The CLARINET automatically shuts-down when USB is suspended
(PC powered off, or USB disconnected) after a short delay:
- 30 s if the device has been configured via USB
- 3 ' if the device is unconfigured, to give time for the
PC to boot
If CLARINET is shutdown with the ON button, the USB cable
must be unplugged-plugged to restart it.
