911 Dispatcher Practice Test

Which code indicates that a unit is unable to copy information?

1. 10-1

2. 10-2

3. 10-3

4. 10-4

The correct answer is: 10-2

The correct code indicating that a unit is unable to copy information is 10-1. This code is commonly used in law enforcement and emergency communication to signal that the receiver is having difficulty understanding the transmission. It is meant to alert other units that there may be a communication barrier, whether due to a weak signal, interference, or other factors impacting clarity. Understanding the 10-codes is crucial for effective radio communication among dispatchers and units in the field, as they provide a concise way to convey complex messages quickly and clearly. In this case, a unit responding with 10-1 informs the dispatcher to either repeat the message or attempt to send the information again under better conditions.
