Serial and Infrared Communications Problems

If a modem doesn't work properly, in Windows Help use the modem
troubleshooter.
If you cannot make a serial connection at high speed (115 K baud), try
changing the Power Management setting in the
Utility to "Moderate" (from "Maximum"): In the SCU, open the Power
menu, select Power Controls, and set CPU Power Management to
Moderate.
For an infrared connection, start Infrared Monitor before you connect. In
Control Panel, double-click Infrared.
If an infrared data connection doesn't work, make sure you're using the
COM4 port (the "virtual" or "simulated" IR port). For printing, use the
LPT3 port instead (as the virtual port), unless you are using an HP
Deskjet 600C or 680C.
If an infrared connection does not work, try disabling it and then re-
enabling it. To do this, open OmniBook Tools and select the
Communications tab. Select Start, Infrared and the Options tab. Clear
the box for Enable Infrared Communications On: (port). Click Apply. Put
a checkmark back in the first box, then click OK.
For an MS-DOS program using an infrared connection, run the program
in an MS-DOS Prompt window instead of in MS-DOS mode.
Try re-aligning the two devices to align their infrared ports. Make sure
the two devices are no more than 1 meter apart.
Check the settings in your communications software and in the
OmniBook's IR Monitor. IrDA must be enabled.

Parallel Port Problems

If a parallel device will not work correctly, its bus speed might be too
slow for the OmniBook. You can decrease the OmniBook's bus speed to
33 MHz by holding down the FN key and pressing the minus key. (To
restore the normal speed, press FN and the plus key simultaneously.)

Sound Problems

Check the configuration of the sound card driver. I/O addresses and
interrupt values (IRQs) are listed in the Getting Started manual.
Check the playback or recording sound levels, channels, and muting—
double-click the speaker symbol in the taskbar.
If the volume keeps reverting to old settings
The hot-key volume and mute controls (FN+UP ARROW,
FN+DOWN ARROW, FN+SPACEBAR) are effective for the duration of
the current audio file only. Use the Windows volume controls to effect a
change permanently.
