Powering The Radio - PERFECTPRO UBOX 500R Operating Instruction

Powering the radio

Battery operation
Installing the batteries: first turn battery cover fixture
anti-clockwise to loosen and open the battery cover.
NOTE
Before you insert the batteries, if you use nonrechargeable
batteries, make sure the NiMH / Alkaline switch which located
inside the battery compartment is switched to Alkaline
position. If you use rechargeable batteries, make sure to
switch NiMH / Alkaline switch to NiMH position.
Insert 6 x AA size (AM-3) battery into the compartment.
Ensure the batteries are inserted in accordance with the diagram
shown. Close the battery cover and fasten the fixture by turning
clockwise. If the radio is not to be used for any extended period of
time, it is recommended that the batteries are removed from the
radio. Reduced power, distortion and a stuttering sound or "Battery
Low" showing on the display are all signs that the batteries need
replacing or recharging. (see below information on "charging the
batteries").
When playing on (rechargeable) batteries the output power is less
compared to the output power when playing on AC mains power.
Because of this the sound can be somewhat distorted at the
highest volume settings.
