3.9 Channel scanning
Scanning is an extension to the dual watch functionality, by which it is possible to watch
multiple channels. It is possible to scan:
• All channels in a sequence
• A number of selected channels in a sequence organized into individual 3 scan tables
- Scan table A, B and C.
The scan type can be selected from the Scanning menu (3). The DW indicator is lit as well
(because the priority channel 16 by default is included in any scan table).
During the scan “SC” is shown in the upper display.
If an active signal is found on a channel different from channel 16 the radio remains on that
channel for 4 seconds (but still respecting dual watch requirements), where after scanning is
resumed. The telephone display is displaying the active channel.
If an active signal is found on channel 16, the VHF is locked on channel 16 until the signal
disappears, where after scanning is resumed. The telephone display is displaying the active
channel (16).
While the active scanning window is visible, scanning can be terminated by:
• Lifting the handset off the hook
• Pressing ´16´ - Channel 16 is used as working channel
• Pressing DISTRESS – Initiates DSC distress
• Pressing – Working channel is used as before scanning was entered
(regardless of carrier state).
• Pressing Replay - Message is replayed
• Pressing any numeric key - Normal channel entry
If scanning is terminated while no active signal was found, the VHF will receive on the
working channel (as it was before scanning was initiated).
If scanning is terminated (handset hook-off) while an active signal is received, the VHF will
operate on this channel after termination.
3.10 Creating scan tables
The scanning tables are user configurable. Creating or editing a scanning table by organizing
a subset of channels (e.g. Table A) for scanning is done by selecting the Edit Scan Table A
entry (3.5.1).
Private channels (non-numeric identifiers – P, F or L) can be part of a channel table. The
number of channels in a scan table is limited to 16.
3 scan tables (A,B & C) can be defined for each enabled channel mode.
Scanning tables are stored during the power-down sequence.
