Radio time DSC logs
are sorted
with wrong
time stamp
or radio
time is
incorrect A wrong radio time indication should occur
only if GPS position source is not connected
or providing correct time data. A valid GPS
time signal will update the UTC time used for
time stamping the DSC logs.
If a GPS/position source is not connected to
the VHF radio and hence position and time is
entered manually, you must enter the "radio
time" also manually, at least after power up.
This will ensure correct time stamping of the
DSC logs.
The UTC time is the suggested time to be
entered when prompted for entering position
and time manually (every four hours).
DSC
Channel

transmissi
on delayed The transmission of a DSC call which is not of

incoming DSC call. As soon as this decoding
process has finalized the transmission will
take place.

of the handset.
Device
failure If any of the checks and tests described in this
section do not assist in resolving the
difficulties experienced in the operation
and/or performance of the VHF installation, a
fault may have developed in the VHF radio
itself.
When contacting an authorized Thrane &
Thrane representative be sure to provide as
much information as possible describing the
observed behavior - also including the type of
the VHF radio, its serial number, and software
release version (both found in the setup
menu Controller Setup).
