Li- ion Battery Pack Precautions
● Do not short the battery terminals or dispose of the battery by fire. Never
attempt to remove the casing from the battery pack.
● Keep the charging temperature always between 5℃ and 40℃.
● Do not use the transceiver while charging the battery pack. We recomme-
nd you switch the transceiver power OFF while charging is taking place.
● Do not recharge the battery pack if it is already fully charged. Doing so
may cause the life of the battery pack to shorten or the battery pack may be
damaged.
● Use the battery pack only for its intended purpose. Never use any charger or
battery pack that is damaged.
● Do not short-circuit the battery. Accidental short-circuiting can occur when
a metallic object such as a coin, clip, or pen causes direct connection of the
positive (+) and negative (-) terminals of the battery. This might happen, for
example, when you carry a spare battery pack in your pocket or purse.
Short-circuiting the terminals may damage the battery or the connecting
object.

Charging the Battery Pack

The battery pack is not charged at the factory, please charge it before use.
Initially charging the battery pack after purchase or extended storage (greater
than 2 months) will not bring the battery pack to its normal operating capacity.
After two or three complete charge and discharge cycles. The full performance
of battery will be achieved.
