Normal/NVG:
Each dimmer channel may be set in one of two modes, Normal and NVG mode, each with their own
brightness levels. If the P139 has been configured with an NVG mode it may be selected by pushing the
appropriate switch on the control panel or external control. The webpage will automatically select Normal
or NVG mode. Only the current mode may be changed.
Restoring Settings: If the dimmer controls have been changed and reverting to a previous version is
required, there are three options. The first is to use the “Restore Previous Settings” control on any of the
settings pages to restore all audio, alert tone and dimmer settings back to a previous version.
The Dimmer Settings page has two controls on each dimmer channel to restore just the dimmer settings
without affecting audio and alert tone settings:
Restore Last Save: Reverts the settings to as they were when configuration mode was started,
or the configuration was last saved in this session.
Restore Defaults: Reverts the settings to their factory defaults.
9.9. Saving and Restoring Configurations
Changes made to ports in the Configuration Web Page are NOT saved permanently unless the user
chooses to save them. If the P139-HD is powered off without saving, changes since the last save will be
lost.
Controls for saving and loading configurations are at the bottom of the Headset Audio Settings and Radio
Audio Settings pages (See bottom of Figure 8).
The Save/Restore controls consist of three boxes:
Active Settings: Shows Date, Time and Comment of the settings currently active.
Save Settings to MMC: Enter a comment in the box and press the Save to MMC button to store
the current settings.
Restore Previous Settings: Select a saved settings file from the drop-down list and press
“Restore” from the MMC card to load the file temporarily.
Once the configuration has been saved, the P139-HD may be powered down and the Ethernet cable
removed.
Note: The new configuration is only copied from the MMC card to the internal memory of the Audio
System when the unit is next powered up. If a new configuration is saved to the MMC card and the card
removed before power is reapplied, the Audio System will not have copied over the new configuration,
and the original configuration will still be installed.
Note: If a previous configuration is restored from the archive, it will not become the current configuration
unless it is saved out again. The audio system always uses the file with the most recent save date.
