Charging Instructions

·The lithium-ion battery is not charged at the factory, please charge the radio at an
ambient temperature of 5 to 40℃ before using it.
·After purchase or long term storage (more than two months), the first charge of the
battery will not bring it to its full capacity. After charging/discharging the battery twice
or three times, it will reach its normal charging effect and battery capacity.
·Before charging, please turn off the power of the radio with battery. It is strictly
forbidden to use the radio while it is charging, as this may interfere with the normal
charging of the battery and cause accidental danger.
·After the battery has been fully charged, remove it from the charging cradle. Don't
shorten the life of the battery by overcharging it for a long period of time. Don't
recharge the battery when the battery energy (electricity) is not fully used up.
Otherwise, it will cause the memory effect of the battery and damage the charging
effect.
·If the normal usage time cannot be reached after fully charged, it means that the
battery life has expired and should be replaced or a new one purchased.

Charging Operations

Place the radio into the built-in desktop charger for charging. During the charging
process, the battery indicator on the screen will indicate the level with the battery
voltage until the battery is fully charged.
