Theradio unit will not accept an ID other than these IDs whichare entered from the keypad. If Inter-fleet Call is enabled,block ID setting affects each fleet group. Status MessageUsing a 2-digit number, you can send and receive a Sta-tus message which may be decided in your talk group. EachStatus may be displayed with 16 alphanumeric characters ifprogrammed in the radio. A maximum of 15 received mes-sages can be stored in the stack memory, and it can be re-viewed after reception. If the message memory becomesfull, the oldest one will be erased. The stack memory will becleared by turning radio power off.• Status 80~99 (Special)Status numbers from 80 to 99 are reserved for specialpurposes.

A radio unit can re-ceive a data message regardless of QT/DQT if the receivingunit is not scanning.• DMS Baud RateFFSK data baud rate setting. The same rate must be setas a communication partner.1200bps :Data communication is made in 1200bps. The communi-cation area is much wider than 2400bps. Recommendedfor repeater operation.2400bps :Data communication is made in 2400bps. The communi-cation area is narrower than 1200bps, but it will decreasethe data traffic. Data rate 2400bps may not work prop-erly depending on the repeater’s characteristic.• Inter-Fleet CallInter-fleet calls allow a radio of one fleet number to call aradio with a different fleet number (radio users can manuallydial a unit ID with a different fleet number).• Status/Short/Long Message on Data Group/ChannelStatus/Short/Long Message transmission is madewhether on the Data Group/Channel.• Status/Short/Unit ID Message Serial OutputWhether a received Status/Short message or PTT ID isoutputed or not to serial port.
