Battery Operation using Alkaline Batteries
1. Remove the battery cover on the back of the unit by sliding the
cover to the OPEN direction.
2. Insert 4 x UM-2 (C size) alkaline batteries into the
battery compartment. Make sure the batteries are inserted with
correct polarity as shown inside the battery compartment.
3. Slide the battery switch to the Alkaline position and then replace
the battery cover.
Important:
When using alkaline batteries, the battery switch must be placed in
the alkaline position. Failure to do so could result serious damage
to the batteries or radio.
4. Decreased of power, distortion and “stuttering sound” are signs
that the batteries may need to be replaced.
5. If the radio is not to be used for any extended period of time,
it is recommended that the batteries should be removed
from the radio. For extended listening, we recommend to
use the supplied AC power adapter or otherwise the
rechargeable batteries.
