Pressing the “STO” key once again assigns the Active Frequency to the selected channel number,
regardless of the channel is “FREE” or “USED” indicated.
The transceiver automatically stores the alphanumeric label assigned to the active frequency.
If the frequency has no label attached, ten underscore digits allow the operator to insert a label.
The cursor automatically appears on the first position (see figures below).
By turning the “ROTARY ENCODER” characters can be selected. Selection works in both
directions (example: blank
A
B
C” by turning clockwise and “C
B
A
blank by
turning counter clockwise).
Each press on the “ROTARY ENCODER“ pushes the cursor to the next position.
A short press of the “STO” key stores the label and a long press of the “STO” key clears the
currently edited label.
After storing labels, the transceiver returns back to the previous frequency selection mode
(standard mode / direct tune mode / scan function).
If no action occurs in label editing mode within 7 seconds, the transceiver returns to the previous
frequency selection mode without storing the frequency and label information.
Stored frequencies can be recalled in channel mode (see chapter 3.5.3).
3.9.2
Automatic Storage Function
The transceiver contains storage function, which automatically stores 9 recently selected VHF
frequencies and updates the last channels database during operation in standard mode, direct tune
mode and scan-mode. To use this function the STORE LAST CHANNEL option must be enabled in
installation setup on the MEMORY OPTIONS page.
When changing to a new active frequency, the previous active frequency is stored “LAST” in
memory channel CH1. The frequencies previously located in CH1, CH2 … CH8 are shifted to
memory channels CH2, CH3, … CH9. This algorithm ensures the last 9 used active frequencies
are stored. Last used frequencies “LAST” can be recalled in channel mode (see chapter 3.5.3).
3.10
Auxiliary Audio Input
The transceiver has a dedicated auxiliary audio input e.g. for MP3 player connection.
When auxiliary input is enabled in the installation setup, the auxiliary audio input signal is mixed
with the received signal from antenna (passing squelch) and the intercom signal (when activated).
When intercom works in ISOLATION mode, then auxiliary audio input signal is provided on
headphone 2 output even if radio communication (transmission/receiving) is active.
AUX AUTO MUTE function depends on the AUX INPUT. It is selected via the CONFIGURATION
page in the installation setup. This function automatically mutes the audio signal from the auxiliary
audio input as long as the GT6201 detects (based on squelch evaluation) a RX signal or the user
deactivates the squelch manually. If this function is disabled the signal from the auxiliary audio
input is permanently audible on the audio output, independently of the received signal or the
squelch status.
Automatic aux attenuation functionality is coupled with the auxiliary audio input. The level of the
auxiliary input signal attenuates if intercom is activated by VOX or by /IC discrete input. The
auxiliary input signal reverts to its previous value after intercom deactivation. The attenuation value
can be adjusted within the range from 0 to 40dB.
