charges for all the calls made during the month.
The charges for calls depend on the time spent time of the day of the week and distance of the recipient from the caller e.g.

iii)Radio calls

The device used is called a radio telephone. It is commonly used in remote areas where normal telephone services are lacking or where telephone services are available but cannot be conveniently used e.g.
policemen on patrol in different parts of a town
Radio transmission is a one way communication system i.e. only one person can speak at a time. It is therefore necessary for the speaker to say’over’ to signal the recipient that the communication is through so that the recipient can start talking. To end the conversation, the speaker says ‘over and out’
The radio calls are commonly used by the police, game rangers, researchers,foresters, ship owners and hotels situated in remote areas.
