Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey a should be less than the compliance level in each frequency range b. Interference may occur in the vicinity of equipment marked with the following symbol: NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. a: Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the FC162 is used exceeds the applicable RF compliance level above, the FC162 should be observed to verify normal operation. If abnormal performance is observed, additional measures may 11 Automatic Fundus Camera USER MANUAL be necessary, such as reorienting or relocating theFC162. b: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. Recommended separation distances between portable and mobile RF communications equipment and the FC162 The FC162 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the FC162 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the FC162 as recommended below, according to the maximum output power of the communications equipment. Rated maximum Separation distance according to frequency of transmitter/m output power of 150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz transmitter W d=1.2 P d=1.2 P d=2.3 P 0.01 0.12 0.12 0.23 0.1 0.38 0.38 0.73 1 1.2 1.2 2.3 10 3.8 3.8 7.3 100 12 12 23 For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.

Maintenance shall be carried out every 2 months according to the method prescribed in Section 3.2-3.4. FC162 is a sophisticated optical device, so be sure to handle it with care. 3.1 Cleaning 1. Cleaning the outer surface of the lens: If the outer surface of the lens is exposed to the air or in a non-clean environment for a long time, and the surface of the lens is dusty. Gently wipe it with soft cotton moistened with anhydrous alcohol, or use a special lens cleaner and cleaning cloth. Note: When the device is not in use, please cover the lens cap to avoid dust on the lens surface. 2. Clean the screen: If dust sticks to the screen, gently wipe it with soft cotton moistened with anhydrous alcohol, or use a special screen cleaner and cleaning cloth. Note: Do not wipe with hard objects. 3. Clean plastic parts: To clean plastic parts such as the device surface, use a soft cloth dipped in soluble detergent or water to clean the dirt, and then wipe it with medical alcohol. Note: Do not use any abrasive cleaning agents, as it may damage the surface. 4. Clean the eye patch: The eye patch is a component that comes in frequent contact with the patient. Cleaning and disinfection should be performed before each patient is examined. Clean the dirt with a soft cloth dampened with a soluble cleaner or water, then wipe with medical alcohol. Note: Since the eye patch is made of silicone, please do not wipe it with any corrosive cleaning agents, so as not to damage it. 3.2 Maintenance The automatic fundus camera should be used in a relatively clean environment. The main parts that need to be cleaned are described in Chapter 3.1. In order to ensure the normal use of the fundus camera, it is recommended to perform cleaning operations every 2 months. After cleaning, wait until the device is dry before using it. Because the surface of the lens is coated with an antireflection coating and a reflective film, although the coating is strong enough, frequent wiping tends to cause damage to 25 Automatic Fundus Camera USER MANUAL the film, which affects the optical effect of observation. This cycle is only a suggestion. If the lens has a particularly large amount of dust that has affected the quality of observation, it is recommended to clean it immediately according to the prescribed method. 3.3 Protection After use, place the device in the mobile carrying case to avoid bumps. 3.4 Battery Care 1. After the battery is fully charged, unplug the power cord to avoid overcharging or danger. 2. If the device is to be stored or remain unused for a month or longer, we recommend that you remove the battery after it is fully charged and place it in the portable packing box. 3. Before removing the battery, please ensure that it is fully charged, and recharge the battery every month. 3.5 Product Life Cycle The life cycle of the automatic fundus camera is 5 years. 26 Automatic Fundus Camera USER MANUAL Troubleshooting If a fault occurs, please check it according to the following table for guidance.
