Last Channel Databa
se
In order to select the new channel number from
LAST
channels database make a counter
clockwise turn on the “ROTARY ENCODER“. The channel number is now highlighted and one of
the nine last used channels is selectable by turning the “ROTARY ENCODER“, either clockwise or
counter clockwise. The mode of channel number selection can be left manually by repeated
pressing of the “ROTARY ENCODER“, or the mode is left automatically after a 5 seconds timeout.
When leaving the
LAST
channels database and the last shown frequency is not stored in one of
the
USER
cannels database, “CH--”will appear on the display.
Accessing the last channels database will be possible if “STORE LAST CHANNEL” is selected on
MEMORY OPTIONS page in the installation setup, otherwise the recently stored VHF frequencies
will not be available.
Note:
If the device operates in
25 kHz mode
,
a selection of an earlier stored 8.33 kHz
channel is not possible. For selection of 8.33
kHz channels, the device must
operate
in 8.33 + 25 kHz mixed mode
.

Scan Mode
In all frequency selection modes;
1. A long press of “↕/SCN” key activates the scan function and changes to STANDARD
MODE if activated from CHANNEL or DIRECT TUNE mode.
2. A short push on the “MDE” key or a long press on “SCN” key terminates scan function.
After leaving scan function, the device will remain in standard mode (chapter 3.5.1).
In scan mode the display shows both the active frequency on the top line and the preset frequency
on the bottom line. The SCAN sign in the display indicates that scan function is active.
If both the active frequency and preset frequency simultaneously detect a signal, the active
frequency takes priority. The preset frequency then inverts and blinks. The arrow sign “►” in front
of the active frequency indicates that this frequency is audible. The figure below shows a sample.
If selected in the installation setup an audio notification “beep” tone becomes audible in addition to
the blinking preset frequency to indicate the presence of an RX signal on the preset frequency.
Reception on Preset Frequency in Scan Mode
If the preset frequency detects a signal while no signal is present on the active frequency, the
transceiver automatically switches over to the preset frequency.
The arrow sign now appears in front of the preset frequency and the signal is audible. The picture
below shows a sample display.
