Green light
– shows normal Status and DA4000SBR is operating normally. No
corrective action necessary.
Green/yellow/orange flickering light
- shows that cellular activity is being transmitted
through the DA4000SBR unit. The light will remain green with low levels of cellular
transmission and change to flickering yellow/orange as transmission increases. The light
may remain green with low levels of transmission.
Solid Red light
– indicates a fault. Turn OFF power switch and proceed with the
following corrective actions:
•
The red light indicates that the inside and outside antennas are located too close to
each other and need to be re-located. A typical installation requires that the inside
and outside antennas have a minimum separation distance of 20 feet and be
separated by an exterior wall. If the inside and outside antennas are not 20 feet
apart or more, relocate the antennas.
•
If the outside and inside antennas are separated by 20’ or more and an exterior
wall. The red light also indicates the use of analog phones.
No light
– indicates missing power to the DA4000SBR unit. Proceed with the following
corrective actions:
•
Verify that the power switch on the DA4000SBR unit is in the ON position.
•
Test for 5VDC power – verify that 5VDC is available on the output plug of P/N
DP255 or DP515. If 5VDC is verified, the DA4000SBR unit may be defective.
See below
o
Test for AC line voltage on the input plug of P/N DP255, 100 to 240VAC
to 5VDC Power Supply. If AC voltage is available and there is no 5VDC
on the output plug. The power supply is defective. See below
o
Test for DC line voltage on the input plug of P/N DP515, 12 VDC to 5
VDC Power Cable. If input voltage is available and there is no 5VDC on
the output plug. The power cable is defective. See below
•
DA4000SBR unit, DP255 or DP515 may be defective. Contact your dealer. The
serial number on the DA4000SBR unit must be available.
e. IN-BUILDING COVERAGE PROBLEMS
If the DA4000SBR unit does not indicate a red light and the coverage area appears to be
smaller than anticipated, one or more of the following may limit the signal strength to the
area.
•
Cell Phone Bars
- The bars on the cell phone do not indicate coverage area. One
bar may be adequate to successfully place and receive calls. Test coverage area by
successfully completing calls while disregarding bar indicator.
•
Physical obstructions degrading the cell signal
– the path of the cell signal is
weakened by objects. Large metal objects block or reflect the signal. Inspect the
coverage area, rearrange any objects in the path of the cell signal or relocate the
indoor antenna.
•
Output Power Control
– The DA4000SBR has an internal output power control
circuit that automatically lowers the power when the inside and outside antenna
are located too close. Verify that inside and outside antennas are located 20’ apart
or more and separated by an exterior wall.
