POSSIBLE CAUSE
• The call sign of the destination repeater is
wrong.
• There is no repeater list in your radio.
, the DR
• The call sign has not been correctly received.
, the re-
• When a received signal is weak, or a signal
is received during scanning, the call sign may
not be received correctly. In that case, "--------"
appears and error beeps sound, and a reply
call cannot be made.
• MY call sign has not been registered on a D-
STAR repeater.
• "External GPS" is selected in the GPS Set
item on the Menu screen, but an external
GPS receiver is not connected.
• "OFF" or "Manual" is selected in the GPS Set
item on the Menu screen.
• A GPS signal was not received.
• While receiving through the internet, some
packets may be lost due to network error
(poor data throughput performance).
• While in the DV mode, an FM signal is re-
ceived.
SOLUTION
• Correctly set the destination repeater call sign. —
• Reload the repeater list using the CS-51PLUS
on the CD or from a mi-
cloning software
croSD backup card.
• Enter the Repeater list data directly into the
transceiver.
• Try it again, after the transceiver has correctly
received the call sign.
• Register your own call sign (MY) on a gateway
repeater, or confirm the registration of the call
sign.
• Connect an external GPS receiver.
• Select either "Internal GPS" or "External GPS"
in the GPS Set item on the Menu screen.
• Move until the GPS signal is received.
• Wait a while, and try it again.
When the transceiver receives corrupted
data, and misidentifies it is as Packet Loss, "L"
is displayed, even if it is a Local area call.
• Use a different operating frequency until there
are no FM signals on the original frequency.
