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 30’ apart
or more and separated by an exterior wall.
•
Cabling
– examine coaxial cable run and verify that the cable is not kinked,
coiled or damaged. Re-locate cable to avoid kinks or coils. If supplied 50’ cable is
damaged contact your dealer. The serial number on the DA4000SBR unit must be
available.
f. COAXIAL CABLE RECOMMENDATIONS
The DA4000SBR system includes 50’ of Digital Antenna’s
TM
ULTRA low
loss cable and connectors for easy installation. If the installed application requires more
than the supplied cable,
TM
DA340 ULTRA low loss 25’ extension cable
and 75’ replacement cable are available. Only Digital antenna cable can be used to
complete the installation. Unauthorized cable usage can be detected and voids the
warranty.
