Coverage/Range
The maximum range depends on terrain condition and is obtained during use in an open space. The only limitation to
maximum possible range are environmental factors such as blockage caused by trees, buildings, or other obstructions.
Inside a car or a metallic constructions, the range can be reduced. Normally the coverage in the city, with buildings or
other obstructions is about 1 or 2 Km. In open space but with obstructions like trees, leaves or houses the maximum
possible range is about 4-8 Km. In open space, without obstructions and in sight, like for example in mountain, the
coverage can be more than 12Km.
Battery recharge
Charging the Battery Pack
The Li-ion battery pack is not charged at the factory; please charge it before use. Charging the battery pack for the first
time after purchase or extended storage (more than 2 months) may not bring the battery pack to its normal maximum
operating capacity. Best operation will require fully charging/ discharging the battery two or three times before the
operating capacity will reach its best performance. The battery pack life may be depleted when it’s operating time
decreases even though it has been fully and correctly charged. If this is the case, replace the battery pack.
Charger Supplied
Please use the specified charger provided by Pofung. Other models may cause explosion and personal injury. After
installing the battery pack, and if the radio displays low battery with a voice prompt, please charge the battery.

a. Do not short the battery terminals or throw the battery into a fire. Never attempt to remove the casing from the battery
pack, as Pofung cannot be held responsible for any accident caused by modifying the battery.

℃
(40˚F - 105˚F) while charging the battery. Charging outside this
range may not fully charge the battery.
c. Please turn off the radio before inserting it into the charger. It may otherwise interfere with correct charging.
d. To avoid interfering with the charging cycle, please do not cut off the power or remove the battery during charging until
the green light is on.
e. Do not recharge the battery pack if it is fully charged. This may shorten the life of the battery pack or damage the
battery pack.
