Below are some guidelines for optimizing comfort of usage and avoiding injury. 1. Put the keyboard and monitor in front of you, and place the mouse within easy reach. 2. Have your elbow next to your side and adjust the height of the table and chair to make the mouse and keyboard placed below your elbow. 3. Have your feet well supported and your shoulders relaxed. 4. Taking frequent short breaks can help ease the tiredness from using the keyboard for a long time. 5. Do not sit in the same position all day operating the keyboard and mouse. Leave the seat, do some exercise for arms and shoulders, and relax your wrists, neck and legs. 6. Beware of discomfort; when you experience body conditions like pain, numbness, or tingling in hands, wrists, arms, shoulders, neck and legs, please consult qualified health professionals. Caution • Do not disassemble the device or operate the device under abnormal conditions. • Do not submerge the device in water. • If the device RGB lights could not be lightened up, please re-plug in the USB. • If the device could not be functional, or there was thermal abnormal situation, please re-plug in the USB. 5 English • If you still encounter problems after going through the corrective measures, please contact your dealer or an authorized service center for assistance. • For more information regarding the PREDATOR accessories, please visit the PREDATOR website at www.acer.com/predator Environment Temperature: • Operating: 0 °C to 40 °C • Non-operating: -20 °C to 60 °C Humidity (non-condensing): • Operating: 10% to 85% • Non-operating: 10% to 95% Manufacturer address Acer Inc. 8F, 88, Sec. 1, Xintai 5th Rd.

Applicable Standards FCC Part 2(Section 2.1093) FCC KDB 447498 D04 Interim General RF Exposure Guidance v01 2. Exposure Evaluation of Portable or Mobile Devices Human exposure to RF emissions from portable devices (47 CFR §2.1093), as defined by the FCC, must be evaluated with respect to the FCC-adopted limits for SAR. Evaluation of mobile devices, as defined by the FCC, may also be performed with respect to SAR limits, but in such cases it is usually simpler and more cost-effective to evaluate compliance with respect to field strength or power density limits. For certain devices that are designed to be used in both mobile and portable configurations similar to those described in 47 CFR §2.1091(d)(4), such as certain desktop phones and wireless modem modules, compliance for mobile configurations is also satisfied when the same device is evaluated for SAR compliance in portable configurations. The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 300 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. Page 3 of 3 Report No. ESTE-R2510021 3. Evaluation Results For 2.4G SRD Field strength = 78.71dBuV/m@3m P={ [10 (78.71/20) /10 6 *3] 2 /30 }*1000mW = 0.022mW< 2.72mW 1. Limited= 3060*(0.5/20)^(- (where f is in GHz); 2. We choose 2.480GHz to calculate limit as lower frequency will have higher limits. End of Test Report
