Possible use of Hitachi cordless tool batteries (sold separately)
The UR 18DSL can be used with a sliding-fit type battery (14.4 or 18 V) or a plug-in type battery (9.6, 12,
14.4 or 18 V) (only 18 V batteries for use in North America).

Highly sensitive large ferrite bar antenna 160-mm long overall for
AM radio
The UR 18DSL incorporates a large ferrite bar
antenna with overall length of 160 mm for the
highly sensitive reception of AM radio waves.
About the sensitivity of AM radio reception
(1) The table below lists the AM radio reception sensitivity measured with a special instrument. Lower
values indicate higher sensitivity.

(2) The table below lists the results of an overall evaluation of AM radio reception status. For evaluation,
three items (existence of interference, degree of noise, and radio disturbance) were examined by
listening, and the evaluated radios were graded in terms of five levels.

=> The reception sensitivity data of the UR 18DSL is slightly inferior to that of product M. However, the
evaluation results based on listening confirm that actual reception performance of the UR 18DSL is
equivalent to that of product M.
