3-3.1.2 Mode and Function Indications
The following indications may appear in the work area of the LCD display, to indicate the selected
mode or functions that are active.
Indication Meaning
USB
Using upper sideband for transmission and reception
LSB
Using lower sideband for transmission and reception
SQ
Squelch is active: the speaker is turned on only when the radio identifies speech, to
prevent reception noise from being heard
MON
When using ALE, indicates that the speaker is normally off, and is automatically
turned on when the link is established
AGC
Non-standard AGC mode (AGC off, or fast AGC) has been selected
BW
Non-standard bandwidth has been selected (the bandwidth appears next to the BW
indicator, for example, 3.3 (3.3 kHz) in the screen shown above)
NB
Noise blanker is active
CLAR
Clarifier is active (meaning that you selected a frequency deviating from the nominal
channel frequency)
NF
Notch filter is active
IATU
Internal ATU enabled (always needed with whip antenna)
EATU
Dipole antenna, or external ATU (internal ATU disabled)
3-3.1.3 RF Level Indications
Indication Meaning
Strong received signal
Weak received signal
Received RF signal strength indication, displayed when the radio is
in the receive mode. The height provides a relative indication,
which may fluctuate as a result of fading, etc.
– Full transmit power
– Relative transmit power
– Low transmit power
– Reflected power
Transmit bar, appears when the radio is switched to the transmit
mode (for example, when the PTT is pressed). Its length indicates
the maximum radio transmit power in the selected mode (MAX,
HIGH, MED or LO). The triangle height indicates the instantaneous
relative transmit output power, and therefore it fluctuates as a result
of modulation.
The relative reflected power is indicated by the base line: its length
indicates the fraction of power reflected because of antenna VSWR
(the length should be small relative to the total height of the
transmit bar, which is proportional to the forward power)
3-3.1.4 Using the Keypad
Each key is imprinted with a numeral and several letters.
These characters are accessed in clockwise order, as follows:
• A single key press enters the numeral
• Two consecutive key presses enter the first letter
• Three consecutive key presses enter the second letter
• Four consecutive key presses enter the third letter.
• Five consecutive key presses enter the fourth letter.
• To enter a blank space, press
0
twice.
