Motorola GP338 explosion-proof walkie-talkies:

切勿在任何危险大气中使用未经防爆检测机构认证的对讲机,否则极易引起爆炸或火灾。 Do not use walkie-talkies that are not certified by the explosion-proof detection agency in any dangerous atmosphere, otherwise it will easily cause explosion or fire.

到物理损坏(例如外壳摔坏),也不可以在危险大气中使用,否则易引起爆炸或火灾。 ● Even if the product is certified for explosion-proof detection structure, if it is physically damaged (such as the casing is broken), it cannot be used in dangerous atmosphere, otherwise it may cause explosion or fire.

● Do not replace batteries and other accessories in hazardous environments. Contact with sparks during disassembly may cause explosion or fire.

● Even if the product is certified by the explosion-proof testing agency, the accessory connector must not be exposed when used in a hazardous atmosphere. When the accessory connector is not needed, it should be covered with a dust cover.

● Do not disassemble the product certified by the explosion-proof testing agency by any means.

● Modify the intercom opportunity to change the original design structure of the intercom hardware. Only the original manufacturer of the product can be retrofitted within the scope approved by the explosion-proof detection structure. Unauthorized modification will invalidate this product's explosion-proof certification.
