When the transceiver is switched on, the upper
line of the display shows the current channel or
the frequency. If a valid tone code is received, it is
displayed in the lower right hand corner of the
display. The lower display line shows an S (signal
strength) meter in the form of a horizontal bar.
This is called the normal state.
To activate the second function of a key, press
the H key. The text ‘Select Function'’ will appear.
The second (alternate) function of the next key
pressed is activated. Press H again to return to
the normal state.

1. Select Frequency
The transceiver operates in one of three modes.
Using the G button you may select between VCO
and Memory mode. The third mode is the
Priority Channel which may be switched on and
off with the F key.
VCO mode
In VCO mode any frequency that complies with
the selected step size (4) may be entered using
the number keys on the keypad. Th e transceiver
automatically rounds off the frequency to a valid
entry. For example, of you want to listen at
435.012.500 MHz, at a step size of 12.5 kHz, all
you need to do is enter ‘501’:
435.---.--- →435.0--.--- → 435.012.500
If a step size of 25k Hz is used, entering '501' will
cause the transceiver to round off to 435.000.000.
Memory mode
Starting from VCO mode up to 100 preset
frequencies per bank may be stored in memory,
see Heading 5. These frequencies may be
selected when in Memory mode while it is also
possible to assign names to channel frequencies.
If no frequency has been assigned to the selected
channel the transceiver produces an error beep
and ignores the number entered.
Priority Channel mode
Provided a frequency has been assigned to the
Priority Channel (see Heading 6), this feature
allows you to change to this frequency at the flick
of a switch. The Calling Channel may be instantly
selected by pressing the F key.
2. Select CTCSS tone
It may be undesirable for every transmission to be
heard on a certain frequency. A system called
CTCSS is therefore used to pass only those
transmissions containing a sub-audible tone of a
specific frequency. In the receiver a CTCSS
decoder is used to open the squelch and make
the transmission (speech) audible when a valid
CTCSS tone is detected.
The frequency of the CTCSS tone may be
selected as follows:
Display:
- Press H( Select Function )
- Press 3( TX CT : **)
The lowest frequency is 67.0 Hz, the highest,
250.3 Hz. The quasi-value 'None' is available to
disable CTCSS. Separate CTCSS frequencies
may be used for TX and RX
3. Tone squelch
The squelch may be remain closed until a valid
ZVEI 5-tone code is received. It is also possible to
transmit a ZVEI 5-tone sequence at the start of
every transmission.
Activate:
The tone squelch is activated by pressing the E
key. When receiving, the yellow LED lights. When
transmitting, the symbol 'T' appears behind the
frequency.
Adjust:
The code may be set as follows:
Display:
- Press H( Select Function )
- Press E ( RX: )
Now set the tone for the squelch. The tone code
has to be entered using the number keys. If a
number flashes, this indicates a DTMF tone.
- Press H( TX: )
Now set the tone to be transmitted.
1750 Hz tone burst
A tone burst is transmitted by pres sing the PTT
and Squelch Defeat buttons at the same time.
The frequency of the tone burst may be adjusted
in the Audio menu.
4. Select Step Size
Display:
- Press H( Select Function )
- Press 8( Step size: ** )
The desired step size is selected by pressing the
0 and # keys (← or →). Confirm your selection by
pressing any other key.
5. Store favourite channels
Up to 100 favourite channels per bank may be
pre-set in the transceiver. A channel is stored as
follows:
Display:
- Select VCO mode (43*.***.*** )
- Enter the desired frequency and choose
SHIFT and/or CTCSS if required
- Press H(Select Function )
- Press G(Store in: xx)
- Select a number, if number has an arrow
in front of it, it has been taken for another
frequency. This is replaced.
(Store in: xx)
- Press H
- If desired, give the channel a name.
(Name: )
See Heading 10 for text entry.
- Press H again
- 3 -
See Heading 7 for the name display on/off
function.
6. Storing Priority (PR) Channel
It is very useful, particularly in mobiles, to have a
single button available to retrieve the Priority
Channel. The Priority Channel frequency may be
programmed as follows:
Display:
- Select VCO mode (43*.***.*** )
- Enter the desired frequency and set
SHIFT and/or CTCSS if required
- Press H. ( Select Function )
- Press F. ( Calling Frequency? )
- Press H.
- If desired, give the channel a name
( Name: )
See Heading 10 for text entry.
- Press H again. ( Processing )
See Heading 7 for the name display on/off
function.
7. Name display on/off
Names may be assigned to memory channels.
The displaying of the name may be switched on
and off, as follows:
Display:
- Press H(Select Function )
- Press 6
8. Clear memory channel
Display:
- Select Memory mode (** ****** )
- Select the channel to be cleared
- Press H ( Select Function )
- Press S ( Clear Channel? )
- Press H ( Processing )
9. Clear Priority (PR) Channel
Display:
- Select Prioruty Channel (button F)
(A ****** )
- Press H (Select Function )
- Press F (Clear Calling?)
- Press H ( Processing )
10. Text entry
Text entry using the keys on the keypad is largely
similar to the method used on GSM phones. For
example, the letters A, B and C are 'behind' the
number key '2'. The desired letter or character is
selected by repeatedly pressing a number key.
The B button is used to delete a character. Text
beyond the cursor position will shift back, just as
with the DEL key when using a word processor.
The E button is used to enter a space.
All characters behind the keys on the keypad are
shown in the table below. The up and down arrow
keys C and D may be used to step through a
character group. The cursor may be moved by
pressing the left and right arrow keys F and G.
On completion of text entry, press the H key.
11. Scanning
De transceiver is capable of scanning in Memory
as well as in VFO mode:
To scan all frequencies:
- Switch to VFO mode by pressing the G button
- Press the * button
To scan memory channels:
- Select MEMory mode by pressing the G button
- Press the * button
Press any key to stop scanning. During scanning
the red LED is illuminated.
If the transceiver has halted on a certain channel,
scanning may be resumed by pressing * again.
During scanning indicator F is displayed.
12. Exclude channels from
scanning
It is possible to skip certain memory channels
while scanning.
Display:
- Select MEMory mode (** 43*** )
- Select the relevant channel
- Press H(Select Function )
- Press *
Indicator E shows that the channel is skipped
during scanning.
