Flashing red light on the 12 VDC power supply (PN DP515)
Model #4KMR-10A includes a new 12vdc power supply with built-in microprocessor controller that automatically stops
power to the repeater (turns the repeater off) in the event of an oscillation (feedback). Please follow troubleshooting
guidelines below.
Please contact Digital Antenna if analog service is being used, the microprocessor 12vdc power
supply can not be used with analog service. Digital Antenna will send you a replacement power supply if analog service is
being used.
The constant red or flashing red light on the power supply indicates the antennas need to be re-
located. The power supply turns off the repeater when an oscillation between antennas is detected.
After the antennas are re-located, reset the power supply by unplugging it from the cigarette lighter and
plug
it back in.
The outside antenna must be centered on the metal portion of the car roof. With a sunroof present, the magnetic mount
antenna should be centered on the metal part of the roof between the sunroof and rear window. Try the inside antenna
attached to the headrest with a rubber or elastic band. Low on the center console may not be the best location for all
vehicles.
During normal operation, the lights on the repeater and the power supply should remain green. Please
contact Digital Antenna if you have tried all above steps and are unable to obtain solid green lights on 12vdc
power supply and repeater.

Troubleshooting Proper Installations:
Even if the antennas are properly separated, a signal bounce could reflect inside the vehicle’s window to the
inside antenna. Walls or large trucks reflect cell signals and may reflect the signal into the vehicle. Once a
signal bounce is detected, the power supply stops power to the repeater. The power supply resets itself
every 90 seconds but will only stay on if the signal reflection is gone. Once the vehicle is moved away from
the wall or truck, the power supply will remain on and the LED will remain green.
The power supply will
reset itself after 90 seconds. After 5 automatic resets, you must manually reset the power supply by unplugging the
cigarette adapter.

The 4KMR-10A system can only be used with a metal roof vehicle; it cannot be used on a convertible or vehicle with a
composite roof structure. Use model DA4000 direct connect amplifier for vehicles with non-metallic roof. Digital Antenna
offers an exchange program to a DA4000 direct connect amplifier within 90 days of 4KMR-10A purchase.
