WARNING: Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12 inches) to any part of the 658, including cables specified by
the manufacturer. Otherwise, degradation of the performance of this equipment could result.

Electromagnetic environment
level
Portable and mobile RF communications equip-
ment should be used no closer to any part of the
SYSTEM, including cables, than the recom-
mended separation distance calculated from the
equation applicable to the frequency of the trans-
mitter.
Recommended separation distance
Where P is the maximum output power rating of the
transmitter in watts(W) according to the transmitter
manufacturer and d is the recommended separa-
tion distance in metres (m).
Field strengths from fixed RF transmitters, as de-
termined by an electromagnetic site survey, should
be less than the compliance level in each frequency
range.
Interference may occur in the vicinity of equipment
marked with the following symbol:

Do you have a question about the ADC Adscope 658 and is the answer not in the manual?
Questions and answers
Not keeping a charge, I have received a new charging cord about a year ago, starting to not keep a charge. please help
The ADC Adscope 658 may not be keeping a charge due to a poor battery connection or a faulty battery. If the battery is properly connected and still does not charge, it likely needs to be replaced.
