Users Manual

Product Appearance Description Note Key1~9 During the performance (left hand on top and right hand on bottom), fingers touch each key separately, and the desired note can be achieved by touching the key according to the fingering (refer to the fingering chart). Note Key 2 (Semicircle key) This note key 2 (semicircle key) is a flat key at any time except when the note key 1 and the note key 3 are pressed at the same time. Users can turn it off in the settings menu if they are not used to it. Chord Keys The EWI-S2 has a major third and major fifth chord function. When the user touches this key during the performance, the desired major third or major fifth chord will be played. Up/Down Semitone Keys Pressing this key during performance will raise/lower a semitone. Vibrato Key When playing, touch this key to produce a vibrato effect. The depth and rate of the vibrato can be set according to your own requirements in the settings. Switch Key +/- The +/- two keys are the sounds selection keys, each short press will increase or decrease to change a sound, and long press will quickly increase or decrease. In the MIDI output mode, it is used as a MIDI channel switch, and when using the user sound bank, it is used as a quick switch sound key. Encoder This encoder is a multi-function setting knob button. Rotate this knob alone in the playing state to switch timbres, hold down the octave center 0 button and rotate this knob to transpose. In the playing state, press and hold for three seconds to enter the setting interface of various parameters. Rotate this knob to select setting items. Press and hold the octave center button and click this button to return to the previous step. Octave Keys The EWI-S2 is designed with a total of seven octaves. When playing, the left thumb presses the center button for a center octave, presses the +1 button for one octave higher, and simultaneously presses the +1 button and +2 button for two octaves higher. Pressing +2 alone is three octaves higher, pressing -1 down is one octave lower, pressing -1 and -2 is two octaves lower, and pressing -2 alone is three octaves lower. Portamento Key Press this key during performance to produce a portamento effect Skill Key Touching this Key with your right thumb during performance will change the Voice to another technique Voice of the currently playing Voice (Instrument).

MIDI DIN Output This jack is a standard MIDI 5-pin output jack, you can use this jack to connect other MIDI devices with a MIDI 5-pin cable to perform. USB MIDI/Charging Jack You can charge the instrument through this jack,also as a firmware upgrade and USB-MIDI output. Power Switch This button is the power switch of the instrument. Press it up and down to switch it. Built-in Speaker The instrument has built-in speakers, allowing you to play solo without an external amplifier. FCC Statement 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 and can radiate radio frequency energy and, if not installed and used in accordance with the 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. Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to operate this equipment. 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.

Exposure category : General population/uncontrolled environment EUT Type : Production Unit Device Type : Portable Device 2. Evaluation method and Limit According to KDB447498 D01 General RF Exposure Guidance v06 Section 4.3.1 Standalone SAR test exclusion considerations: “Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition, listed below, is satisfied. These test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions.22 The minimum test separation distance is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander (see 5) of section 4.1). To qualify for SAR test exclusion, the test separation distances applied must be fully explained and justified by the operating configurations and exposure conditions of the transmitter and applicable host platform requirements, typically in the SAR measurement or SAR analysis report, according to the required published RF exposure KDB procedures. When no other RF exposure testing or reporting is required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for the SAR test exclusion. When required, the device specific conditions described in the other published RF exposure KDB procedures must be satisfied before applying these SAR test exclusion provisions; for example, handheld PTT two-way radios, handsets, laptops & tablets etc.“ [(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 Page 2 of 4 FCC ID: 2A84YEWI-S2 Shenzhen LCS Compliance Testing Laboratory Ltd.

When the minimum test separation distance is < 5 mm, a distance of 5 mm according to f) in section 4.1 is applied to determine SAR test exclusion. When one of the following test exclusion conditions is satisfied for all combinations of simultaneous transmission configurations, further equipment approval is not required to incorporate transmitter modules in host devices that operate in the mixed mobile and portable host platform exposure conditions. The grantee is responsible for documenting this according to Class I permissive change requirements. Antennas that qualify for standalone SAR test exclusion must apply the estimated standalone SAR to determine simultaneous transmission test exclusion. a) The [∑ of (the highest measured or estimated SAR for each standalone antenna configuration, adjusted for maximum tune-up tolerance) / 1.6 W/kg] + [∑ of MPE ratios] is ≤ 1.0. b)The SAR to peak location separation ratios of all simultaneously transmitting antenna pairs operating in portable device exposure conditions are all ≤ 0.04, and the [∑ of MPE ratios] is ≤ 1.0. 3.
