5-6 Viking Mobile Radio Operating Manual
Conventional Mode Features
When the Call Guard code is changed using this feature, it remains selected even if other
channels are selected. However, if radio power is cycled or a talk-around channel is
selected, the normal codes are reselected. When scanning, the selected code also applies to
all scanned channels. Each channel can also be programmed to always ignore the code
selected from this list and use the default code instead.
If both analog and digital (Project 25) channels can be selected or scanned, the CTCSS/
DCS code for the selected position is used for analog channels and the NAC code for the
selected position is used for P25 channels. If a channel is programmed for mixed mode
operation, the selective squelch type (analog or digital) programmed for the transmit mode
determines the selective squelch type used.
Note Call Guard codes may be permanently reprogrammed by keypad programming (see
Section 5.14).
Proceed as follows to select a code using the Squelch Select List option switch:
1 Press the Squelch Select List option switch and then rotate the Select switch to select
the desired position. The display indicates “SQ xx” where, “xx” is the selected code
from 1-255. The code number and actual code are alternately displayed (NACs are
displayed in hexadecimal).
2 To select the displayed code and return to the normal display, press the Squelch Select
List (Squelch Code Select) switch again.
3 To check which code is selected, press the Squelch Select List option switch once to
display the current selection and then again to return to normal operation.
4 To return to the normal selective squelch codes, select “DEFAULT” in this mode. As
previously described, the normal codes are also automatically reselected whenever
radio power is cycled or a talk-around channel is selected.
5.5 Penalty Timer
A penalty timer may be programmed on conventional systems to prevent transmissions for
the programmed time after the time-out timer disables the transmitter (see Section 4.3).
The penalty timer can be programmed for the same times as the time-out timer, and timing
starts when the PTT switch is released. If the PTT switch is pressed while the timer is
running the timer stops, and continues when the PTT switch is released. When the penalty
timer expires, a beep sounds and the transmitter can then be keyed.
