JEM Radio II
Operation Guide
Channel Entry
A channel entry consists of entering 6 digits. The first 3 are the AAR TX channel and the second
three are the AAR RX channel. The default RAN of 01 (Freq, 67.0Hz) will automatically be used
on digital channels when the channel is changed. If a different RAN code is required, it can be
entered using the RAN button where the first 2 digits is the TX ran code and the second is the
RX ran code.
Shortcuts
If only 3 digits are entered, it will be assumed that the RX channel should be the same as the TX
channel and the new channel will automatically be selected after the timeout period or the
CHAN button is hit.
If a non default RAN code is required, the RAN button can be hit immediately after the 3
rd
digit
instead of the CHAN button. This will confirm the channel entry just like hitting the CHAN
button but will also automatically prompt for the new RAN codes.
Text Messages
A text message that is received either from an NXDN packet or from the network will be scrolled
across the display once, after which MSG will blink in bottom right corner of display.
If a text message is received before a previous message is finished scrolling, the new message
will begin scrolling immediately and the previous message will be saved. Messages will be saved
in non-volatile memory.
There is an option in the GENERAL menu to replay any of the last 10 text messages received.
The SCROLL MSG option number is set to ‘1’ by default which is the last message received.
Simply selecting the SCROLL MSG option and then hitting the MENU button will play the last
message. Changing the message number allows selecting older messages with ‘10’ being the
oldest. Selecting ‘0’ will play all 10 messages.
Any message received by the radio when in menu mode will be stored and displayed once menu
mode is exited.
After a message is received, the text “MSG” will be displayed every second until the user
acknowledges it by hitting any button.
