2ACGI-TX900BP900MHz digital bodypack transmitter

1. ON/OFF: Main power control. 2. LED Display: Blue indicates power on; Red indicates battery is charging. 3. SET - (Microphone Gain): Press to adjust the microphone gain between 0-9, (0 is the lowest setting and 9 is the highest setting). The factory default setting is 3, therefore every time the ON/OFF (1) is cycled, the transmitter will default back to 3. Note: The “LOCK” (4) needs to be in the “UNLOCK” mode. 4. LOCK: Press for three seconds until the lock icon disappears from the display to enter into the Programming Mode. Press it again for three seconds to return to the Lock Mode. 5. ˂(Low Pass Filter): Increasing the filter setting decreases unwanted high frequencies while maintaining an acceptable audio range; this is adjustable from 1-8. The display area will go blank once it is scrolled past 8, which indicates the filter is off. Note: The default setting is OFF. Note: “LOCK” (4) needs to be in the “UNLOCK” mode. 6. ˃(Channel): Use to scroll through the available channels, 1-12. Note: The “LOCK” (4) needs to be in the “UNLOCK” mode. 7. USB: Charging port 8. Mic-In/Line-In: The mono 3.5mm jack accepts wired microphones or audio devices that have a line-level output, this includes MP3 players, IPODS and CD players. 900MHz DIGITAL BODYPACK TRANSMITTER Model Number ARG-TX900BP QUICK USER GUIDE 1. The ARG-TX900BP has a lithium battery pack installed. Before initial use, you will need to charge the battery. When fully indicating the battery is charged and ready for use. The charging cycle is approximately 3 ½ hours andthe transmitter can operate for up to 20 hours in between charging cycles. The battery level is displayed on the bat tery level indicator located on the LCD display. Note:Battery removal must be done by a factory trained professional. 2. Insert the included microphone into the Microphone-Input Jack located on the side of the transmitter. 3. Turn the power switch to “ON” position and the LCD backlight will appear. 4. Adjust the channel number to match the channelnumber on the receiver. Note:When using two transmitters simultaneously, bothmust be set to different channels. Note:The transmitter must be in the “UNLOCKED” mode. 5. Adjust the Microphone Gain setting and the Low Pass Filter setting, if needed. Note:The transmitter must be in the “UNLOCKED” mode. 6. Maintain line-of-site operation with the speaker, if possible. Note:The transmitter and speaker should be as close as possible to each other, but no closer than three feet. 7. When finished using, slide the “ON/OFF” switch to the “OFF” position. Note:For extended periods of storage, make sure to fully charge the battery before storing. charged, the red charge LED indicator will shut off This device complies with Part 15 of the FCC Rules. 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help.

FCC ID: 2ACGI-TX900BP RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where f(GHz) is the RF channel transmit frequency in GHz Power and distance are rounded to the nearest mW and mm before calculation The result is rounded to one decimal place for comparison Worse case is as below: Frequency (GHz) Distance (mm) Power (dBm) Power (mW) Cal. Density (mW/mm) Exclusion Threshold (mW/mm) 0.904 5 7 5.01 0.95 ≤3.0 0.916 5 7 5.01 0.96 ≤3.0 0.926 5 7 5.01 0.96 ≤3.0 Then, as a result, SAR evaluation is not required
