Viking Mobile Radio Operating Manual
General Operation
Note
In dual control configurations, the power switch at either control point can be OFF for
power to turn OFF.
3.1.1.1
Setting Volume Level
The relative volume setting can be determined using a reference tone as follows:
• If the key press tones are enabled (see Section 4.6) and if so programmed, a short tone
sounds when an option switch is pressed or the Select switch is pressed or rotated.
• If a conventional channel is selected, take the microphone off-hook and if someone is
talking, voice may be heard. If the MON (Monitor) option switch is programmed (see
Section 5.2), pressing it unsquelches the radio and either voice or background noise is
heard. If a SMARTNET/SmartZone or P25 trunked channel is selected, the radio cannot
be manually unsquelched.
The minimum volume level that the volume control can select can be programmed. This
can be used to prevent missed messages caused by unintentionally turning the volume
down too far. Relative levels of 0-255 can be set in steps of 1 (“0” sets the lowest
minimum volume).
Note
This setting is applicable to Viking mobile radios with Viking Remote Control Heads
.
3.1.1.2
Unprogrammed Tones
The Viking mobile radio can be programmed so that it will not play a tone in the following
cases:
• Unprogrammed button pressed.
• Unprogrammed toggle switch activated.
• Switched to an unprogrammed channel.
3.1.1.3
Standard and Soft Power Down
To turn power off, press the ON-OFF/Volume knob.
A Soft Power Down feature can be programmed to prevent radio power from being turned
off by accidentally pressing the on-off/volume knob. The display message portion of the
display stops updating. The user is able to receive, transmit, and use function buttons, but
the display message will not change. If the channel is changed the Zone/Channel
indication will update.
The user can power the radio completely down by pressing the option button programmed
for this purpose (F2, F6, or Select button).
