To clean, remove dust and dirt with a lint free soft cloth, soft pap

26、er tissues or cotton balls. Clean with a mild detergent and water and blow dry or dry by using the soft cloth or tissues. Deep scratches may reduce the protection. This may be checked by running a fingernail over the scratch. If the fingernail catches the scratch, the visor should not be worn. THIS

27、VISOR IS A CON ;OLLE0 ITEM AND SHOULD BE DISPOSED OF IN ACCORDANCE WITH NAVAI R Manual 13-1 -6.7 This visor shall be worn only during daylight hours. It does not transmit enough light to be worn during the low light levels of dawn, dusk or at night. This visor is not intended as a replacement for th
