Sidetone
The sidetone is available on the headphone output during transmission.
•
The sidetone volume depends on to the intercom volume adjustment.
•
Squelch Operation
The squelch (muting) circuit suppresses signals with strong signal noise.
•
There are two kinds of squelch methods implemented, carrier- and noise-squelch.
•
o
The carrier-squelch depends on the signal strength and is adjustable in
configuration setup.
o
The noise-squelch depends on the noise level and is adjustable in the user menu.
Memory Channels
You can can store 99+9 frequencies.
•
o
The user can give a defined text label to each stored frequency.
The last recently used 9 (active) frequencies are stored automatically as "LAST"
o
channels.
Scan Mode
The scan mode is a dual watch function.
•
o
The device monitors frequencies on two different channels, active & preset
frequency at the same time.
o
The signal of the active frequency is always audible it has priority at all times.
Illumination
•
The illumination of LCD and keys is controlled from the front panel with the user menu or
externally with the dimming input lines.
If external dimming is selected, the illumination curve (brightness to voltage relation) is
•
adjustable in the configuration setup.
LOW BATT Indication
The transceiver monitors the power supply voltage.
•
o
If the power supply voltage is less than the adjusted threshold, the display shows
the message "LOW BATT".
o
If the power supply voltage decreases further, an emergency operation mode
starts.
Emergency Operation
If the power supply voltage is < 10.25 V, the device continues operation with decreased
•
performance.
•
If the power supply voltage is < 9.0 V, the device turns off automatically.
Built-In Tests
Power-On Built-In Test
After power-on, the device starts a self-test (PBIT).
•
The display shows the message "WAIT" and the software versions of the control
o
head and the chassis module.
o
If there is an error the display shows the message "FAILURE, push any key".
o
If there is no error the transceiver changes to the last active mode before power
off.
Continuous Built-In Test
•
During normal operation, a self-test (CBIT) permanently examine the correct operation of
the device.
o
The display shows an error message, if there is an error during CBIT.
