(1) Batterien und Akkus
Besitzer von Altgeräten haben Altbatterien und Altakkumulatoren, die nicht vom Altgerät umschlossen sind, im Regelfall vor der Abgabe an einer
Erfassungsstelle von diesem zu trennen. Dies gilt nicht, soweit die Altgeräte bei öffentlich-rechtlichen Entsorgungsträgern abgegeben und dort zum
Zwecke der Vorbereitung zur Wiederverwendung von anderen Altgeräten separiert werden.

b) Der Nutzer ist zur Rückgabe gebrauchter Batterien gesetzlich verpflichtet.
(2) Getrennte Erfassung von Altgeräten
Elektro- und Elektronikgeräte, die zu Abfall geworden sind, werden als Altgeräte bezeichnet. Besitzer von Altgeräten haben diese einer vom

und Rückgabesysteme.
(3) Möglichkeiten der Rückgabe von Altgeräten
Besitzer von Altgeräten aus privaten Haushalten können diese bei den Sammelstellen der öffentlich-rechtlichen Entsorgungsträger oder bei den von
Herstellern oder Vertreibern im Sinne des ElektroG eingerichteten Rücknahmestellen abgeben. Ein Onlineverzeichnis der Sammel- und
Rücknahmestellen finden Sie hier:

6.1 RF Safety 射频辐射安全（注：TX 产品适用）(Note: TX products are applicable)
RF energy, which when used improperly, can cause biological damage. Please refer to the following websites for more information on what RF
energy exposure is and how to control your exposure to assure compliance with established RF exposure limits: http://www.who.int/en/
For users who wish to further reduce their exposure, some effective measures to reduce RF exposure include:
➢ Reduce the amount of time spent using your wireless device.
➢ Use a speakerphone, earpiece, headset, or other hands-free accessory to reduce proximity to the head (and thus head exposure). While wired
earpieces may conduct some energy to the head and wireless earpieces also emit a small amount of RF energy, both wired and wireless
earpieces remove the greatest source of RF energy (handheld device) from proximity to the head and thus can greatly reduce total exposure to
the head.
➢ Increase the distance between wireless devices and your body.
6.2 免证发射机专用 Dedicated to license-free transmitter
This radio is designed for and classified as “General population/uncontrolled use”. General population/uncontrolled environments are defined as
locations where there is exposure of individuals who have no knowledge or control of RF exposure level.
7.1 Electromagnetic Interference/Compatibility 提醒无线电干扰（电子产品适用）
Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed, or otherwise configured for
electromagnetic compatibility. During transmissions, your radio generates RF energy that can possibly cause interference with other devices or
systems. To avoid such interference, turn off the radio in areas where signs are posted to do so, such as hospitals or healthcare facilities.
9.1 Protect your ears 保护听力
• Use the lowest volume necessary to do your job. Turn up the volume only if you are in noisy surroundings.
• Limit the amount of time you use headsets or earpieces at high volume.
• When using the radio without a headset or earpiece, do not place the radio's speaker directly against your ear.
• Use carefully with the earphone maybe possible excessive sound pressure from earphones and headphones can cause hearing loss.
CAUTION: Exposure to loud noises from any source for extended periods of time may temporarily or permanently affect your hearing. The louder the
radio's volume, the less time is required before your hearing could be affected. Hearing damage from loud noise is sometimes undetectable at first
and can have a cumulative effect.
10.1 Batteries Safety 电池安全使用警示语,
•WARNING: KEEP NEW OR OLD USED BATTERIES OUT OF REACH OF CHILDREN.电池放置到儿童接触不到的地方
•In the event of a battery leaking, do not allow the liquid to come into contact with the skin or eyes. If contact has been made, wash the affected area
with copious amounts of water and seek medical advice immediately. 如果电池泄漏，请不要让液体接触皮肤或眼睛。如果有接触，用大量的水冲洗
受影响的区域，并立即寻求医疗建议。
•If a radio or a battery has been submerged in water, please dry and clean it before use. Do not dry the radio or battery with an appliance or heat
source, such as a hair dryer or microwave oven. If the radio has been submersed in a corrosive substance (e.g. saltwater), rinse the radio and battery
in fresh water, then dry them.如果收音机或电池已浸入水中，请在使用前将其擦干并清洗干净。请勿用吹风机或微波炉等器具或热源吹干收音机或电
池。如果收音机已浸泡在腐蚀性物质(例如盐水)中，请在淡水中冲洗收音机和电池，然后将其干燥。
10.3 电池可由普通用户更换的警示语，
•Turn off your radio before removing or installing a battery. Store spare batteries securely. Dispose of used batteries immediately and safely.在拆卸或
安装电池之前，请先关闭对讲机。请妥善保管备用电池。立即安全地处置用过的电池。
•Batteries should be removed from the appliance when not being used for long periods of time (months). The batteries should be enclosed in special
protective packaging (such as sealed plastic bags or variants) which should be retained to protect them from condensation during the time they are
warming to ambient temperature.长时间(数月)不使用时，应将电池从设备中取出。电池应封装在特殊的保护包装中(如密封的塑料袋或变体)，以防止
