2.5.2 Adjustments
On the side of the PAC45/HUB45R are six adjustment potentiometers.
1. Alert volume (adjusts the level of the internal audio alerts and annunciations
generated by the PAC45)
2. White & Green text backlight level adjust (see §2.5.2.1)
3. Unswitched input 1 volume
4. Unswitched input 2 volume
5. Unswitched input 3 volume
6. Unswitched input 4 volume
2.5.2.1 Green and White lighting adjustment
The #2 potentiometer adjusts the white intensity by default.
The green indication level can be adjusted to match the white level or for user preference. This
should be done before adjusting the white, as setting the green will overwrite the white setting.
1. Hold the ACK and HRTF buttons at the same time until a chime is heard in the headset.
2. Adjust the #2 potentiometer (see §2.5.2, above).
3. Push ACK to exit the green adjust mode, and return to white adjustment.
4. Adjust the white text lighting as desired with #2 potentiometer.
2.5.2.2 Green and White lighting adjustment (Configuration BBGAA)
Units with Configuration BBGAA and above, the dimming has been modified to set a
minimum level:
• By default, adjustments to the pot change the minimum trip point for the dim-
mer input to full bright. The pot permits adjustment from 0V to nominal dimmer
voltage (28V or 5V depending on configuration).
• Long press (3 seconds) of HRTF and ACK on pilot panel will cause the #2 potenti-
ometer to adjust the green level, when in this mode the green LEDs will get
brighter or dimmer.
• Another long press (3 seconds) of HRTF and ACK on pilot panel will adjust the
white level
• Another long press (3 seconds) of HRTF and ACK to exit
• Also, ACK can be pressed at any time to exit (if you want to adjust green but not
white for example)
2.5.3 Logic Switch Options
The PAC45 has several switches accessible through the side of the HUB45 to set specific func-
tions
