If the outside and inside antennas are separated by 20’ or more and an exterior
wall, the red light may be indicating the use of analog phones. Contact Digital
Antenna if you are using an analog phone.
No light
on Repeater
– indicates improper installation and the power supply is stopping
power to the repeater or no power is available. Proceed with the following corrective
actions:
•
Only after all cables and antennas are securely attached, verify that the power
switch on the DA4000MR unit is in the ON position.
•
Unplug the 12VDC power supply from the repeater and the power source. Re-
plug the 12VDC power supply into the power source and test for 5VDC power on
the output plug. 5VDC will only be available if the power supply light is green on
the black box and solid red on the cigarette adapter. 5VDC will not be available at
the plug if the LED on the power supply box is flashing red. The power supply
must be reset by unplugging it from the power source.
•
If the red light continues to flash on the power supply box after reset (unplugging
from power source and plugging back in), the antennas need to be re-located until
the light on the power supply box and repeater remain green. If analog service is
being used, contact Digital Antenna.
e. INTERIOR COVERAGE PROBLEMS
If the DA4000MR 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 DA4000MR 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 at least
20’ apart or more and separated by an exterior wall.
•
Weak Outside Signal
– If the outside signal is very weak, the interior coverage
area will be small. To increase coverage area, use one of Digital Antenna’s high
gain outside and/or inside antennas (pg 15).
•
Cabling
– examine coaxial cable run and verify that the cable is not kinked,
coiled or damaged. Re-locate cable to avoid kinks or coils. The serial number on
the DA4000MR unit must be available.
The repeater system only amplifies existing outside cell signal; it does NOT create a cell
signal. If no outside signal is present, the repeater has no signal to amplify. The outside
antenna should be mounted as high as possible to capture the available cell signal.
