GRATING SPECTROPHOTOMETER OPERATION MANUAL Please read this manual carefully before use the spectrophotometer. Safety Instructions Please read carefully and strictly abide by the following provisions to avoid accidental injury or harm. The company shall not be liable for any loss arising from the use of the instrument in violation of this manual. Battery 1. This instrument uses built-in battery which can not be replaced with other batteries, in case of damage to the instrument or other malfunctions. 2. Do not dismantle, squeeze, strike and heat the battery, and do not put the battery in the fire or high temperature environment, otherwise the battery will explode and cause fire. 3. When the instrument is fully charged and not in use, cut off the external power supply to prevent electric shock and instrument damage. 4. If the instrument is not used for a long time, charge the instrument every two weeks, or the internal battery may be damaged and the instrument cannot be used again. 5. For the first three times of charging, it is better to get fully charged and then use it out before next charging. External power 1. When external power supply is required, please use the standard power adapter of the instrument, or it may shorten the battery life or even cause electric shock to damage the instrument or cause fire. 2. If the instrument is not used for a long time, the external power should be cut off to prevent burning the instrument Grating Spectrophotometer and causing fire. Instrument 1. Do not use the instrument in a place with flammable gas (gasoline, etc.), as this may cause a fire. 2. Do not dismantle the instrument privately, or it will be damaged. And if dust and metal foreign objects may enter the instrument, it may cause short circuit, generate electric shock, and damage to the instrument, even cause fire. 3. If the instrument emits peculiar smell like burning when using it, it should be stopped immediately and sent to the maintenance point for testing and maintenance. 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.

Standalone SAR test exclusion considerations Unless specifically requi red 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 correspondi ng SAR Exclusion Thres hold condition, listed below, is satisfied. 2.2 Limits 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 nd distance are rounded to the nearest mW and mm before calculation 17 The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 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 3 EUT RF Exposure GFSK Channel Maximum Peak Conducted Output Power (dBm) Tune up tolerance (dBm) Maximum tune-up Power Calculated value Exclusion threshold (dBm) (mW) Lowest (2402MHz) 2.543 2±1 3 1.995 0.618 3.0 Middle (2440MHz) 2.357 2±1 3 1.995 0.623 Highest (2480MHz) 2.362 2±1 3 1.995 0.628 Conclusion: the calculated value ≤3.0, SAR is exempted.
