The red LED goes ON.
The Power LED does not
turn ON.
Yellow/Red Flashing LED
The Alert LEDs continue
to ash.
Your signal booster has
no power.
More antenna separation is needed. If you cannot provide more
antenna separation and the Alert LEDs ash after the initial activation
period, lower the dial above the blinking LED by 5dB (for example,
from 50 to 45) and monitor the bars on your cell phone to see
whether reception improves.
Be sure the AC outlet is working and is not controlled by a wall
switch that can cut power to the outlet.
Oscillation is detected. First try increasing the separation between
the indoor and outdoor antennas. If this doesn’t eliminate oscillation,
lower the dB gain in 5dB increments.
The signal booster shuts down automatically, and then restarts after
60 seconds. Turn down the PCS or Cellular dial that is oscillating to
prevent the signal booster from shutting down automatically.
This may indicate that additional antenna separation is needed.
Verify that the switch on the power supply is turned on and Green
LED is ON.
Connect the power supply to an alternate power source.
Be sure the power source is not controlled by a switch that can
remove power from the outlet.
Check the green POWER LED on the signal booster. If it is OFF,
return the power supply to SureCall. Contact tech support at 1-888-
365-6283 or [e-mail], or go to www.surecall.com and
log on to online support to receive an RMA.
Troubleshooting
Red Flashing LED
Your signal booster restarted
and shut down for 15 minutes,
and is now shut down
permanently.
Signal coming into booster from cellular tower is too strong causing
the booster to automatically shut down. There are two possible
solutions:
1. Add an inline attenuator to the cable coming into the booster
2. Relocate the EZBoost to a location where the signal is weaker.
Each SureCall signal booster is equipped with Auto Shutdown to
prevent cell tower interference. The outside antenna may be close
to a cell tower. Move the outside antenna to a location that provides
sucient distance from the cell tower to prevent the signal booster
from automatically enabling Auto Shutdown. Once away from the
original location.
Problem Resolution
