5. Troubleshooting
Before contacting your service dealer, please make sure you refer to the following guide. If
the QUAD BAND OTA does not work normally after completing the following troubleshooting
tips, please contact your local dealer or service center.
Case 1) LED indicator is not normal
Problem Check Point Solution
Critical POR LED is red Power supply out of range
- Confirm AC 85 - 264V common use power and
power cable.
TD LED is red Tamper detected
- Check the status of the BDA equipment.
BTF LED is red Built-in test failure
- Check which alarm occurred through the WEB
GUI Alarm status.
- UL Out-of-band emissions, DL Spurious
emissions, DL Interferer power exceeded, DL
Low isolation, Over temperature
- Case 2) Problem solving by Alarm indicator.
RMF LED is red Replaceable module failure
- select BDA’s alarm LED is red
- reset BDA’s power
- BDA’s alarm LED is still red,

Technical Support
OSC LED is red Oscillation detected
- Check Donor/Server ant. Isolation and if the
value of Gain is less than +5dB, adjust the
location of antenna to secure isolation.
SD LED is red Shutdown
- Check the S/D reason using WEB GUI.
- If the Manual HPA is Off, turn it back On.
- If Overpower S/D occurred and Manual Gain is
setting up, control the Gain setting.
- If Overpower S/D occurred and the ALC is On,
set up the ALC Level 1 to 3dB low. Fix the
ALC Level if it is normal after monitoring for so
long. (It can be possible to occur if Input
Power change is extreme.)
Minor DCF LED is orange Donor Circuitry failure
- DL Donor Power too high
- After checking the DL input Power, adjust the
location of the antenna or install the external
antenna to the permitted range if it is over the
permitted level
DPL LED is orange Donor power too low
- DL Donor Power too low
-.If the DL input Power is too low, adjust the
location of the antenna to be at a high input
value.
CCF LED is orange Coverage Circuitry failure
- UL Power at coverage high, DL VSWR
- If the DPL LED is normal but the CCF LED is
not normal, reduce the UL Gain. (If ALC is On, it
can reduce the UL Gain by controlling the Gain
Offset.)
