RECEIVE – ANALOG CHANNELS

The radio can only receive broadcasts while the Push-To-Talk button is not being pressed. Whether or not you hear these

broadcasts depends upon the squelch settings.

There are three standard squelch modes that can be used when on an Analog channel

Carrier Squelch Lets you hear all broadcasts on your channel strong enough for the radio to detect, and silences noise.

Tone Squelch Uses the QC or DQC “tone squelch” format available on the base radio to screen unwanted calls.

Paging Decode 2-Tone, DTMF or Selcall can be used in conjunction with either carrier or tone squelch to block out all calls

except those sent specifically to your radio. When the unique paging decode sequence programmed into the

radio is decoded, the radio will emit a series of ring tones similar to a telephone.

When receiving a signal with Carrier or Tone Squelch - The display will indicate the Channel Name and “RX”

will appear on the 2

line. The incoming signal will be heard on the radio speaker.

When receiving a signal with a Paging Code - When the base radio decodes an incoming Paging signal it will

emit a “ring” tone similar to a telephone, the display will indicate the Channel Name, and “Call” will appear on

the 2

line. The incoming signal will be heard on the radio speaker.

When a received signal is present that does not carry the correct QC/DQC and/or Paging Code - The display

will indicate the Channel Name and “Busy” will appear on the 2

line. The incoming signal will not be heard on

the radio speaker.

To override QC/DQC and/or Paging Decode and hear all received signals - The base radio can be set to

receive all signals, regardless of QC/DQC and/or Paging Code.

 Press and release the P2 BUTTON until “Monitor” appears on the display.

 The display will indicate the Channel Name and “Mon” will appear on the 2

line. All activity on the

channel’s radio frequency will be heard on the radio speaker.

 If you are unable to activate the Monitor function, the channel has been programmed for Monitor Lockout.

 To disable the Monitor function, press and release the P2 BUTTON until “Monitor Off” appears on the

display.

TRANSMIT – ANALOG CHANNELS

 Normally, you should monitor the channel before transmitting and talk only when the channel is clear. If

“Busy” or “RX” appears on the 2

line of the radio display the radio channel is in use and you should not

transmit until the channel is clear.

 To transmit - hold down the Push-To-Talk button and, with the radio at least 6 inches away, talk into the

microphone. Speak in a normal tone, since talking louder will not improve the listener’s reception.

 The display will indicate the Channel Name and “TX” will appear on the 2

line.

 Keep talk times as short and infrequent as possible to allow others to use the channel.

 Transmitter Time Out - If you hold down the PTT button longer than 60 seconds a low tone followed by a

higher-pitched tone will sound on the radio speaker and the transmitter automatically shuts off. Release the

PTT button to resume normal operation.

QC AND DQC TONE CODES – ANALOG CHANNELS

Tone codes filter out static, noise and reduce unwanted “chatter” on radio channels. When you operate on a frequency with a tone

code, you screen out most interference. This allows you to communicate with less interference and to hear only those users in your

radio group.

IMPORTANT! All radios in the talk group must operate on the same frequency and tone code.
