Charging a USB device
The RH4-18V's USB port can also be used to charge USB
devices. The USB port has an output power of 5V / 1A.
To charge a USB device (e.g. iPhone, smartphone or
similar device), just open the USB rubber cover on the
right side of the radio and insert / connect it to the USB
port. After charging has finished, don't forget to remove
/ disconnect the device again and close the USB rubber
cover to prevent moist or dust from entering the radio.
Charge time may vary and in some cases may take longer
to charge than when using the manufacturers charging
unit supplied with the smart phone.
IMPORTANT:
● The USB jack can only provide power for the USB
memory stick only with 1A 5V maximum and most of
iPhone models. However, it does not support external
Hard disk drive and all mobile phones and electronic
device.
● The maximum volume of the output power speaker will
decrease when your USB is charging.
● The charger may not supply power to some USB devices.
● Do not connect power source to USB port. Otherwise
there is risk of fire. The USB port is only intended for
charging lower voltage device. Always close the USB
rubber cover when not charging the lower voltage
device.
● Do not insert a nail, wire, etc. into USB power supply
port. Otherwise a circuit short may cause smoke and
fire.
● Do not connect this USB socket with your PC USB port,
as it is highly possible that it may cause breakdown of
the units.
