Charging the battery
Always charge batteries with the system-compatible chargers supplied by Funkwerk.
These are optimally suited for the radio set and the battery. Always use the chargers
outside of hazardous areas (explosive atmospheres).
Charging the battery with a FT4 Desktop Charger II / FT4 Desktop
Station
The Desktop Charger II FT4 and Desktop Station FT4 chargers charge both the
battery in the radio set and a spare battery. When the radio set and the spare battery
are connected with the charger at the same time, the battery in the radio set is
charged first. After this, the charging process of the spare battery starts. The char-
ging time for an empty battery is roughly 5 to 8 hours.
