FIND OUTSIDE LOCATION WITH STRONGEST SIGNAL

Using your phone, identify the outside location with the strongest signal. This is generally found on the side facing your nearest cell tower and as high as possible. Capturing the strongest possible signal with your outside antenna will provide the best resulting coverage.

Bars are not always a reliable measure of the signal. The best way to confirm signal coverage is the ability to place and hold a call. Putting your phone in Field Test mode will also indicate what level of decibels (dB) your phone is receiving. For dB measurements, use the methods below. Note that dB measurements appear as a negative where a number closer to 0 indicates a better signal (-120 dB indicates no service, while -50 dB would be considered an excellent signal).

Apple iPhones: Dial 3001#12345# and press Call. A dB number will appear in the top-left corner.
Android devices: download the app “Network Signal Info” in the Google Play store.

Before installation, ensure there will be adequate separation between the planned locations of the outside antenna and booster (at least 25 ft.).

INSTALL THE OUTSIDE ANTENNA

Once you have located the area of the strongest signal, mount the antenna to a pole or pipe (not included) at the highest possible elevation. The directional Yagi antenna works best when facing the direction of your carrier’s cellular tower. To find the location of your carrier’s closest cell tower goes to www.cellreception.com.

To install the outside antenna, assemble the u-bolt, bracket, nuts, and washers as shown in the illustration. Keep the connections loose enough to allow the antenna to rotate until the optimum direction is found.

Note: The outside antenna may be installed on a variety of surfaces. Ensure that the mounting area has at least a 24-inch radius clear of obstructions and other radiating elements and orient the antenna with the drip hole at the bottom.
Once the outside antenna is secured, connect one end of the provided 50 ft. coax cable to the antenna and tighten the connection.

Note: Avoid placing either component (booster or outside antenna) near windows where possible as it increases the potential for oscillation.

PLACE THE BOOSTER

Place the Flare DB+ signal booster in a central location where cellular reception is needed, at least 25 feet from the outside antenna and close to an AC outlet. When placing the booster, note that further separation between the booster and outside antenna will increase booster performance.
Route the cable from the outside antenna to the booster location and tighten the connection.

CONNECT TO POWER

Once the booster and the outside antenna are connected, connect the power cord to the Flare DB+ booster and plug it into a 110V AC power outlet.
Place a call in the room where the booster is located to confirm that your phone is receiving a boosted signal.

LED Indicators
NOTE: Normal operation is indicated by LEDs that are OFF -or- YELLOW Flashing. Only the presence of RED LEDs indicates potential need for adjustments. Note that power cycling the booster after each adjustment may be necessary.

LED
Position| LED
Condition| Indication
---|---|---
Right or
Left| OFF| The booster is operating normally
Left| Yellow
Flashing| Automatic Gain Control (AGC) is self-adjusting. This is part of a normal operation.
Right| Yellow
Flashing| Indicates Automatic Gain Control (AGC) is active and the booster is self-adjusting. This is part of normal operation and, whether intermittent or ongoing, does not require action.
Left| Red
Flashing| The booster is receiving too strong of a signal which may cause one or more of the supported frequency bands to shut off. Unaffected frequency bands will not be impacted, however, and continue to receive enhanced signals.
If this happens but your signal is still improved: It is possible that the impacted frequency bands are not used by your carrier and thus, no action is needed. If this happens and your signal has not improved, consider the following options:
• Relocate the outside antenna to a location where the signal is weaker
• Adjust the angle of the Yagi antenna by rotating it in small increments away from the cell tower until Red flashing stops.
Right| Red & Yellow
AlternatelyFlashing| One or more of the supported frequency bands have shut off. Unaffected frequency bands will not be impacted, however, and continue to receive enhanced signals.
If this happens and service quality has not improved, consider the following options:
• Try increasing antenna isolation by adding vertical distance between the outside antenna and Flare booster.
• Ensure the Yagi antenna is not aimed in the direction of the Flare booster.
• Check for sources of interference such as cellular modems or hotspots. Added separation from the Flare booster may be needed.
Keep in mind, identifying the setup that yields the best possible results for your environment will come from testing — balancing between the elimination of interference while receiving the best possible signal.

If you Want to Improve Coverage

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 the outside antenna.
Optimize the angle of your outside antenna by testing at small incremental rotations.

Troubleshooting

Problem	Resolution

Signal booster has no
power| Connect the power supply to an alternate power source.
Verify that the power source is not controlled by a switch that has removed power from the outlet. If the POWER LED ( ) on the signal booster is OFF, contact tech support at: 1-888-365-6283 or support@surecall.com
After completing the installation, indoor signal coverage has not improved| (1) Verify that all cable connections are tightly fitted.
(2) Try further separating the booster and antenna.
(3) Verify that there is a usable signal where the outside antenna is placed.
Remember: Bars are not always a reliable measure of the signal. The best way to confirm the signal
coverage is the ability to place and hold a call.
