Clear Call amplifies signals from the nearest base station and re-transmits them at higher power level. Clear Call provides service at 700MHz LTE, 850MHz Cellular, 1900MHz PCS and 2100MHz AWS frequencies without any additional setup or configuration. Clear Call User Guide Clear Call User Guide Clear Call User Guide Splitter and several internal antennas may be required in some spaces where signal improvement is required for large houses or buildings. For example, in spaces where signal improvement is required, the signal from Clear Call can be divided into two or more signals using splitter (sold separately) and connected to an internal antenna (sold separately). These optional components can amplify the signal into the required space.

If technician is required to conduct repairs due to major alarm, repeater should first be powered off, and then technician should prepare the proper measurement equipment before trying to fix the problem. In most cases of major repairs, GST will simply replace the unit and conduct repairs at the appropriate facility. Simple Troubleshooting Method 1) Check LED status at rear of module

- Green LED on: Normal operation with maximum allowable gain.

- Red LED on: Shutdown by oscillation condition or over output. 2) Check external and internal connectors to ensure that all connections are tightly secure. 3) If user thinks there is a serious problem, call after sales team for over-the-phone technical support. 913-469-6699. Clear Call User Guide ALC (Auto Level Control) ALC maintains limit of the output power in order to protect bad influence to the Base Station. AGC (Auto Gain Control) The Signal Booster checks isolation between inside and outside antennas once a day. AGC sets up downlink and uplink gain value automatically depending on the input power level. ASD (Auto Shutdown) There are two cases when ASD works. 1) Outside antenna and Inside antenna are not isolated enough from each other. So in order to protect the Signal Booster from damage, it will automatically shutdown at this frequency. 2) Uplink Signal coming from the outside antenna to Base Station is too strong and may cause troubles to carriers network, so the Signal Booster will shutdown at this frequency.

These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. FCC Part 15.21 statement the user's authority to operate this equipment. Any changes or modifications not expressly approved by the party responsible for compliance could void RF Exposure Statement The antenna(s) must be installed such that a minimum separation distance of at least UL : 170cm, DL :

20cm is maintained between the radiator (antenna) and all persons at all times. This device must not be co-

located or operating in conjunction with any other antenna or transmitter. Use of unauthorized antennas, cables, and/or coupling devices not conforming with ERP/EIRP and/or indoor-only restrictions is prohibited. Clear Call User Guide RSS-GEN, Sec. 7.1.2 (transmitters) Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum

(or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformment la rglementation dIndustrie Canada, le prsent metteur radio peut fonctionneravec une antenne dun type et dun gain maximal (ou infrieur) approuv pour lmetteur par Industrie Canada. Dans le but de rduire les risques de brouillage radiolectrique lintention desautres utilisateurs, il faut choisir le type dantenne et son gain de sorte que la puissance isotroperayonne quivalente (p.i.r.e.) ne dpassepas lintensit ncessaire ltablissement dune communication satisfaisante. RSS-GEN, Sec. 7.1.2 (detachable antennas) This radio transmitter (identify the device by certification number, or model number if Category II) has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. Le prsent metteur radio (identi_er le dispositif par son numro de certi_cation ou son numro de modle sil fait partie du matriel de catgorie I) a t approuv par Industrie Canada pour fonctionner avec les types dantenne numrs ci-dessous et ayant un gain admissible maximal et limpdance requise pour chaque type dantenne.

Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Clear Call User Guide If the Signal Booster is not in use for 5 minutes, it will reduce gain until a signal is detected. If a detected signal is too high in a frequency band, or if the Signal Booster detects an oscillation, the Signal Booster will automatically turn the power of on that band. For a detected oscillation the Signal Booster will automatically resume normal operation after a minimum of 1 minute. After 5 minute such automatic restarts, any problematic bands are permanently shut off until the Signal Booster has been manually restarted by momentarily removing power from the Signal Booster. Noise power, gain, and linearity are maintained by the Signal Boosters microprocessor. The detailed information was included in the Operational description.
