Please follow these tips before calling the Sansonic
hotline for assistance:
1) Read and review all sections and follow all instructions in this
manual.
2) Before terminating speakers to SPKR1 (J3-Right) + SPKR2 (J4-
Left), verify that all wiring is free from shorts, opens, crosses or
ground problems. Please verify polarity of speaker wiring (+/-).
3) After connecting power supply (J5); verify that LED’s have lit on
the front HB card panels and backplane in J1 and J2 positions for
both HNB-A and HNB-B (Green LED). If there is no power LED
light on HNB-B; verify wiring in the RJ45 to meet EIA-568B per
section 4.7 and 4.8 (power on pins 3+6). If there is no light and AC
power source is confirmed; verify that polarity (+/-) wiring is correct
with Red or Ribbed wire as (+) positive. Use front panel soft button
and IR remote control to cycle power On/Off.
4) If no Override page is heard and input audio sources are not
muted during “master-override” page; verify wiring termination
polarity (+/-) to the MO connector and insure ‘Volt Sens’ POT on
rear is adjusted correctly and front MO-IN ‘orange’ LED lights.
5) If after power and system terminations have been made and no
audio is detected, insure volume gains are adjusted properly and
that all speakers are of the proper impedance and/or have correct
impedance-matching transformers (25V or 70V / see HNB-70V2X
section 5.2) installed.
6) If video signal / picture does not appear at AV projector, please
verify LED’s are “on” (Green) at the HB-V front panel and HB-VR
receiver which includes power and signal (see section 6.3 to 6.6).
Insure all CAT5e/RJ454 terminations meet EIA-568B (section 4.7
and 4.8) and terminations of VGA, S-video and Composite video
are made properly at the AV projector. Finally, insure the AV
Projector and source are transmitting and set to compatible source
and resolution (see section 6.6). NOTE: Image quality such as;
Color, Brightness, Focus, Blurring are most likely adjustments in
the projector, computer and or video source.
7) It the HB-IRRC remote control does not function please check the
AAA batteries (x2) to insure a full charge. Also check to insure
direct sunlight or strong florescent lights are not interfering.
Reminder: The IR remote control will not operate beyond (50) feet.
8) If you continue to experience difficulty, please call Sansonic at
