© 2010, GS Teletech, Inc.  Version 0.2  May 2010 RF Configuration Menu FAQ’s • What is the relationship between AGC (Auto Gain Control) and ALC (Auto Limit Control)? ALC is for custom installations, and AGC is automatically used when AGS is turned on which is for normal installations. If the repeater is having difficulties with isolation check, or if you wantto “power down” the repeater ALC should be manually set. Attenuation may also be addedfor reducing power levels. ALC also provides optional U/L and D/L settings. - The relationship between AGC and ALC is that they both will control the output power, but in different ways. AGC will take priority over ALC, meaning if AGC is on, ALC cannot be used. - If you want to use the ALC function, AGC should be turned off. - The difference is that ALC will reduce max gain by the set value even if the input signal decreases. AGC will limit the total output power to a set value while still allowing the repeaterto fluctuate to max gain if input signal gets weaker. • What does the Shutdown ON/OFF control? - An internal wave-detection is checking the noise level. If the repeater cannot secure isolation it will go through a process of turning itself off, and turning back on while doing isolation checking. - If it is impossible for the repeater to secure isolation after 30 minutes, the repeater will shut down and stay shutdown. The items that may automatically require the repeater to shut down are: -> VSWR Alarm, Over Power Alarm, and Over Input Alarm • What is Gain Balance Control? - Gain Balance Control will always keep the UL and DL ATT the same while using AGC. GBC should always be left on to prevent damage to BTS while using AGC. - This is used for BTS to cell phone power control. © 2010, GS Teletech, Inc.

Version 0.2  May 2010 RF Configuration Menu • For normal setup, GST recommends using the Auto Gain Setting. • User may configure gain and secure isolation by switching Auto Gain Setting to “ON”. • Click “Apply”. • The default values in various fields will differ with different models of CDMA Repeater. © 2010, GS Teletech, Inc.  Version 0.2  May 2010 RF Configuration Menu • After setting AGS to ON and clicking Apply, the screen below will be displayed while AGS is initializing. • After AGS is completed, click “Click Result”. The equipment will set AGC, Gain Balance and HPA “ON”, and then provide normal service. If automatic setup works you will see the Status page. (ALC “ Off ”) © 2010, GS Teletech, Inc.  Version 0.2  May 2010 AGS Flow Chart © 2010, GS Teletech, Inc.  Version 0.2  May 2010 RF Configuration Menu • If AGS process fails, it is most likely one of 3 issues: -> 1st) too weak input signal, 2nd) too strong input signal, or 3rd) the Donor and Service antennas are too close to each other. To resolve, antenna tuning is required. • In case of 30dBm, if isolation is below Gain +7dB, i.e. 97dBc, this warning will be displayed. © 2010, GS Teletech, Inc. 0 Version 0.2  May 2010 Alarm Configuration Menu • Click Alarm Configuration link. • In case that Report Alarms is OFF, all alarms will be disabled.

RESULTS The power density level at 36 cm is 0.79923 mW/cm², which is below the uncontrolled exposure limit of 1.0 mW/cm² at 1957.5 MHz f or PCS band. Warning: In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, it must also have a minimum distance of 36 cm from the body during normal operation.
