Introduction

Congratulations on your purchase of the ClearCell + Plus Cellular Signal

Booster. Designed to improve and enhance cellular telephone performance,

the Signal Booster will attract and strengthen cellular signals in homes

with little or no service. As a result, you will experience fewer dropped

and miss calls, less audio breakup while talking, and an increase in your

phone’s battery life between charges.

With only two major components—the Patch Antenna and the Base

Amplier--the Cellular Signal Booster is easy to install and requires no

attic, outdoor, or roof access. Tools are necessary only if you want to

wall-mount the Booster Base. RANGE and SIGNAL indicators on the Base

Amplier’s display will aid you in the installation process and ensure the

Cellular Signal Booster reaches and maintains optimal performance.

The following pages provide further information on how the ClearCell +

Plus Cellular Signal Booster functions, as well as a detailed guide to its

proper installation and use.

IMPORTANT NOTE: It is critical that you perform the Site Evaluation

before you proceed any further. This evaluation determines if you have a

minimum signal level from your Cellular Service Provider, which is required

for the Cellular Signal Booster to function properly. If you have virtually

no signal and cannot place a phone call from anywhere in your home, the

Cellular Signal Booster cannot solve your problem.

Site Evaluation It is critical to pre-evaluate the home in which you are planning to install the ClearCell + Plus Cellular Signal Booster. This is to determine whether or not an adequate signal from your cellular telephone carrier’s system base station is reaching your home, which is necessary to allow the Cellular Signal Booster to do its job. The evaluation involves a simple 2-step process and your cellular handset. Using your handset, walk around the home in which you plan to install the product.

Installation and Setup Overview The following is an overview of the installation process. To ensure the product’s best operation, we highly recommend following the “Detailed Installation Procedure” on page 12. 1. Find the strongest signal near a window a window in your home with your own cellular handset’s signal bars. 2. Attach the included Patch Antenna approximately 12 inches from the top of the window with the strongest signal. 3.

How Does It Work? The Problem If you have poor cellular service within your home—if you frequently have no service and repeatedly experience dropped and missed calls— it could be because the walls in your home are disrupting the cellular signals traveling to and from your cellular handset.
PAGE 7
The Solution How Does the Cellular Signal Booster Work? The Cellular Signal Booster has two antennas, one that links to your cellular carrier’s system base station (Patch Antenna), and another that links to the cellular telephone handset within your home (Service Antenna.) Between these two antennas are two directional amplifiers that boost both cellular carrier system base station signals and your cellular telephone handset signals (Fig. 3.) Patch Antenna Service Antenna Carrier Base Station Amp.
PAGE 8
To install the Cellular Signal Booster System properly, the Patch Antenna should be mounted on the window in your home closest to your cellular carrier’s system base station. Since windows have little to no signal degradation, the Patch Antenna can receive cellular signals and route them into your home through a Radio Frequency Coaxial Cable that leads to the Base Amplifier.
PAGE 9
Note that because the amplifiers in the Cellular Signal Booster’s input and output ports are tuned to the same frequency, oscillation (feedback) between the Patch and Service Antennas can occur if they are placed too close together (Fig. 5.) The effect is similar to that of a microphone that is held too close to its output speaker; you will hear a loud whistling (oscillation) noise.
PAGE 10
The circuitry that reduces amplification levels and shuts down the system is known as Automatic Gain Control (AGC.) Fig. 6 shows both the feedback loop and additional circuitry used to avoid problems with feedback/ oscillation.
PAGE 11
Note, however, that if the AGC activates and reduces the amplification level of the Cellular Signal Booster amplifiers, the Cellular Signal Booster system will not perform at its peak because the output signals emitted by the antennas will be weaker reducing the signal levels received by both your handset and the Carrier Base Station. It is possible to control the level of AGC deployed by making sure the Patch and Service Antennas are installed at a sufficient distance apart.

Detailed Installation Procedure 1. As was done during the Site Evaluation earlier, using your cellular handset, find the window that gives you the strongest signal as indicated by the bars on your handset. 2. Attach the rectangular Patch Antenna to the mounting bracket by sliding it on the square post at the end of the bracket (Figs. 8 and 9.) Loosen the Adjustment Nut and make sure you have the latch in the Open position. The ClearCell + Plus label faces away from the Bracket (Fig. 10.
PAGE 13
3. Clean the inside of the window at the location you will be mounting the Patch Antenna, preferably about 12 inches from the top. Use a cleaning liquid that does not leave residue, such as rubbing alcohol. 4. With the locking latch in the open position (Fig. 9) press the clear suction cup against the clean glass and lock the latch into place as shown (Fig. 11.) The Patch Antenna will be loose on the bracket, but it will be tightened in a later step. Latch Closed Figure 11 5.

7. The unit will initialize itself in approximately 5 seconds. The blinking CHECKING indicator will disappear when it is okay to proceed. 8. Once the initialization process is completed, adjust the Patch Antenna direction such that it yields the maximum number of bars on the SIGNAL meter shown in the circle below (Fig. 13.) Then tighten the Adjustment Nut to lock the antenna in that position. This process tunes the antenna for the best possible link with your carrier’s base station.
PAGE 15
10. Connect the small Service Antenna to the Cellular Signal Booster Base as shown below (Fig. 14.) Figure 14 11. Orient the Service Antenna upward and the Base Amplifier in one of the two positions shown below. Fig. 15 is the proper orientation for a wall-mounted unit, Fig. 16 for tabletop placement.
PAGE 16
12. Connect the AC Adapter to the Base Amplifier and plug it into an AC outlet in the location where you plan to install the Base Amplifier. 13. Once the unit has initialized itself (as in Step 8) adjust the position of the Base Amplifier to achieve the highest number of concentric bars in the RANGE indicator, circled below (Fig. 17.) The RANGE indicator shows the size of the area the Cellular Signal Booster will cover in your home. The more bars showing, the better the coverage and performance.
PAGE 17
15. Periodically monitor the LCD indicators to ensure the installation remains stable. If any of the indicators experiences a drastic reduction in bars, inspect the complete installation and correct any problems. Note: Over time your Cellular Carrier may have system outages, will add, or modify a Base Stations in your area. This may cause a change in the performance of your Cellular Signal Booster System.

17. After the wall-mounting bracket is installed, simply slide the Base Amplifier over the hooks as shown below (Figs.

Troubleshooting Symptom No power light Possible Solution Make Sure AC Adapter is plugged into working AC outlet. Make sure AC Adapter plug is fully seated into repeater base. The ALARM can only be turned off by disconnecting the power and reconnecting Cannot turn off ALARM Mode it after you have adjusted the antenna distances. ALARM comes on when tuning the Patch Antenna The small Service Antenna must be disconnected during the tuning of the Patch Antenna.

Troubleshooting - Continued Symptom Possible Solution A plus or minus one bar change is normal. Environmental conditions and changes in your home (objects being moved or people movement) can change these levels. If the change is more drastic: 1) Something has changed in your installation. Inspect the Antennas The RANGE and/or SIGNAL and correct any changes. See step Indicators have changed 15 of the Detailed Installation their number of bars. Procedure.
