Using the Battery

2.1 Precautions
When the battery is out or not used for a long time, please charge it before use.
After two or three charge‐discharge cycles, an ideal battery capacity can be achieved. When the battery is low, please charge or replace it.

Note:
Do not throw the battery into fire.
While charging an attached battery, turn off the transmitter before charging so that it can be fully charged.
Continuous charging shortens the battery life. Disconnect the charging cable when charging is not needed. For example, when the battery is fully charged, disconnect the charger in time. When the ambient temperature is above 35 ℃ or below ‐10, dischargeable capacity may be reduced, which is determined by the physical characteristics of a lithium battery. Please keep the ambient temperature between ‐10 ℃ and 25 ℃.

2.2 Charging the Battery
(1) Plug the power adapter into a required AC power socket.
(2) Connect the magnetic charging cable to the charging port of the product.
Note:  If you use an external microphone, you may connect the charging cable to the port on the microphone, without removing the microphone.
(3) Blue indicator light is on. Charging begins.
(4) After charging for about 4 hours, the blue light is off and the green light on. The battery is fully charged.
(5) Continue charging for 1 to 2 hours, and then disconnect the charging cable. Now the performance of the battery reaches its best.
(6) Remove the power adapter.

Note:
The battery is delivered without being charged. Please charge it before using it for the first time.
Turn off the transmitter before charging.
When the battery is charged for the first time or has been not used for more than 2 months, charge it several times so that it works normally.
To ensure battery capacity, charge the battery once per three months at least.
When the battery capacity is full or above the level triggering a low‐power alarm, do not charge the battery, so as to ensure the lifespan and performance of the battery.
After the transmitter enters a low‐power state, charge the battery fully before powering on again, so as to ensure the lifespan and performance of the battery.
