To override DMR Squelch Type and hear all received signals
 The base radio can be set to receive all DMR signals, regardless of Squelch and ID programming.
 Press and release the P2 Button until “Monitor” appears on the display.
 The display will indicate the Channel and “Mon” will appear on the 2
nd
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 – DMR CHANNELS
Normally, you should monitor the channel before transmitting and talk only when the channel is clear. If “Busy”
appears on the 2
nd
line of the display the radio channel is in use and you should not transmit.
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 radio will transmit the Primary TX Contact code programmed into the channel. This will normally be a
Group call type contained in the DMR Contacts list.
 When transmitting the DMR Primary TX Contact name will appear on the 1
st
line of the display and TX will
appear on the 2
nd
line.
 Keep talk times as short and infrequent as possible to allow others to use the channel.
P1 BUTTON – DMR CHANNELS
The P1 button is used to select DMR Contacts that can be used to communicate with other radio talk groups, or with an individual
user. The RBS-Series radio can be programmed with 48 Individual or Group Contacts. Any number of the 48 Analog contacts can
be assigned to the P1 button on a per-channel basis.
 Press and release the P1 BUTTON until the desired DMR Contact appears on the display.
 With the DMR Contact name showing on the display, press the PTT button and the radio transmits with the
selected DMR Contact code.
 Upon release of the PTT button, the radio will continue to operate on the selected DMR Contact for 10
seconds to allow a response from the Group or Individual.
 If there is no response and the PTT button is not pressed within 10 seconds, the radio reverts back to the
programmed channel operation.
 This feature is only available on DMR channels.
