46 Troubleshooting and repair Welch Allyn VSM 300 Series
Update the Monitor
To minimize the possibility of interruption during the update:
• Do not run other applications on the PC during this process.
• Do not disconnect the monitor from the AC power adapter or the computer until
Finished is clicked and Update Monitor has been refreshed.
• Set the Power scheme on the PC to Always On to prevent it from turning off the
monitor or hard disk and going into standby or hibernation mode.
• Make sure the PC and the VSM are connected to a stable power source.
• Do not connect power cords to switched outlets.
• Do not connect power cords where they may be inadvertently disconnected.
If the update does not complete, the VSM reports an E40 error. Reinstalling the software
might result in a recovery.
If the installed software is current:
• Update is grayed out.
• Update Status is “Up to date”.
• Upload Status is blank.
Caution If the update is interrupted, the VSM monitor might be left in an
unusable state.
Caution This upgrade procedure might return monitor user settings to the
factory defaults. To create a record of the current settings, select View Logs,
click Cal & User Logs, and save the current log.
