Problem Resolution
Signal booster has no
power
Verify that the switch on the power supply is turned on and red 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 to receive an RMA at:
1-888-365-6283 or [e-mail], or go to www.surecall.com during business hours to chat with a
representative.
After installing your
signal booster system,
you have no signal or
reception.
Be sure your signal booster’s dB gain is turned up to full power on each dial.
Verify that cable connections are tightly tted to the booster and antenna.
Try further separating the antennas.
Remember: Bars are not always a reliable measure of signal. The best way to conrm signal coverage is the ability
to place and hold a call.
LED Color LED Resolution
Yellow Solid Indicates that that frequency band is not being used. After a period of time, if there’s no activity, that band
will go into sleep mode. Light is o while band is active. This is part of normal operation.
Yellow Flashing Indicates that the Automatic Gain Control (AGC) is self-adjusting. This is part of normal operation.
Red Flashing Indicates that the booster is receiving too much signal which could cause the aected band to automatically
turn o. When this happens:
1. For kits using an OMNI outside antenna, relocate the outside antenna to a location where the signal is
weaker.
2. For kits using a YAGI outside antenna, turn the antenna in short increments away from the signal
source.
3. Increase the separation between antennas (additional vertical separation works best).
4. Add an inline attenuator to the cable coming into the outside port of the booster.
5. Though not desirable as amplication will not be optimum, turn down the dB gain on the dial until the
light goes OFF or ashes yellow.
Red Solid The frequency band is o.
If a red light has been ashing for an extended time due to too much signal, that frequency band will display
a solid red light indicating that the circuitry for that frequency band has been turned o.
This can also happen when the gain dial for that frequency band has been turned all the way down.
Yellow/Red Alternately
Flashing
Self-oscillation has been prevented.
First, try increasing the separation between the inside and outside antennas. If your booster kit uses two
directional antennas (example: outside Yagi antenna and inside panel antenna), ensure that they are facing
away from one another.
If condition continues, lower the dB gain setting in small increments until the light turns o or ashes yellow.
