Notice
The monitor screen for this unit may exhibit an undesirable
horizontal disturbance if placed in close proximity to other electrical
devices. This permissive loss of performance is specified by the
manufacturer and will not damage the scanner or monitor. Known
solutions to this type of problem are as follows.
1. Rotate the scanner 90 degrees. This will sometimes eliminate
or minimize the effects of the interference.
2. Move the scanner away from the source of the Radio
Frequency Interference.
