Installation
3. Slide antenna securely onto mounting plate.
4. Connect antenna to one end of the SC-240 cable and run to planned location of your booster
5. Place the booster on a at surface or mounted to a wall and connect the remaining end of the SC-240 cable to
booster port marked INSIDE.
IMPORTANT:: FCC 27.5 (d)(4) Statement: Fixed, mobile, and portable (hand-held) stations operating in the 1710-1755 MHz band as well as mobile
and portable stations operating in the 1695-1710 MHz and 1755-1780 MHz bands are limited to 1 watt EIRP.
Place the Booster
To install the booster to a wall, select a location that is near a working AC outlet. Use the supplied screws or
appropriate screws for surface of mounting location and drill through screw tab holes on booster (see “Booster
Diagram” on page 10) and mount the booster to a wall.
Next, connect the outside antenna and booster by connecting the open end of the 50 ft. cable leading from the
outside antenna to the port of the booster marked “OUTSIDE”.
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 section.
Step 5: Congure Gain Settings If Needed
Place a call in the room where the inside antenna is located to conrm that your phone is receiving a boosted signal.
Note: Bars are not always a reliable measure of signal. The best way to conrm 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 specic 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 11 do not resolve the issue.
It is best to avoid turning the gain dial below 40 dB as this could cause aected 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 most eective.
• If using an omni outside antenna, upgrade to a directional yagi antenna that can be aimed toward your closest
tower.
