The manual channel’s frequency is displayed in place of the alphanumeric identifier for preset channels. Once the
manual channel is selected, press the EDIT button to edit the channel information. The C-5000 automatically stores
the manual channel information on power down.
Using the Direct/Repeat Feature
The C-5000 supports both direct and repeat modes of operation. Any preset channel that has identical transmit and
receive frequencies is considered a direct channel. If the transmit and receive frequencies are different, the C-5000
considers the channel a repeater channel. Repeater channels can be temporarily changed into direct channels by
pressing the DIR button. This will temporarily copy the receive frequency into the transmit frequency. The direct
mode indicator will light. The following illustration shows radio 1 in direct mode.

Receiving/Transmitting
Receiving
The C-5000 is constantly monitoring its radios for reception. When a signal is received, the C-5000 will light the
receive indicator for the receiving radio, and route the audio to the operator’s headset (Assuming the associated
intercom switch is selected). The following illustration depicts Radio #1 receiving.
