Step 4: Connect to Power and Turn On

Connect the AC power cord to the booster and plug into a 110V AC power outlet. Once the booster has been

completely assembled, turn the booster’s power switch to ON.

Note: If the Power LED does not turn ON or the Alert LEDs continue to ash, see the ”Troubleshooting” on page 14

section.

Note: This booster is rated for 5-15V input voltage. DO NOT use the booster with a higher voltage power supply. This can damage the booster, cause personal injury,

and void your warranty.

Step 5: Congure Gain Settings If Needed

Place a call in the room where the inside antenna is located to conrm that your phone is receiving a boosted

signal.

Note: 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.

Booster gain dials or switches should always be at maximum level unless the control light for a specic

frequency band is ashing red or ashing red-yellow. In either case, only reduce gain dials if the recommended

actions found in “LED Indicators” on page 13 do not resolve the issue.

It is best to avoid turning the gain dial below 40 dB as this could cause affected frequency band to stop

amplifying.

IF YOU WANT TO IMPROVE PERFORMANCE

• Identify a location outside that receives a stronger signal and move the outside antenna to that location

(higher is usually better.

• Increase the distance between the booster and outside antenna - vertical separation is better than

horizontal.

• If using an omni outside antenna, upgrade to a directional yagi antenna that can be aimed toward your

closest tower.

Condition

Resolution

OFF This is part of normal operation. Light is off while band is active.

Yellow Solid

This is part of normal operation. Indicates that the frequency band is not being used. After a period of

time, if there’s no activity, that band will go into sleep mode.

Yellow Flashing

This is part of normal operation. Indicates that the Automatic Gain Control (AGC) is self-adjusting.

Red Flashing Indicates that the booster is receiving too much signal which could cause the affected band to

automatically turn off. 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, lower the dB gain setting in small

increments until the light turns off or ashes yellow.

Red Solid The frequency band is off.

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 off.

This can also happen when the gain dial for a frequency band has been turned all the way down.

Yellow/

Red

Alternately

Flashing

Self-oscillation has been detected and to prevent it, one or more of the frequency bands have shut

down.

If this happens: First, try increasing the separation between the inside and outside antennas. If your

booster kit uses 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 off or ashes

yellow.
