4-2 Viking VM600 Mobile Radio Operating Manual
General Operation
If the Radio ID feature is enabled, the radio will display the Radio ID alias in place of the
Self Test message during startup. Radio ID identifies the personality file used to program
the radio, the service area for which the radio is programmed, or functional grouping for
which the radio is programmed. The Radio ID alias display will be included with the
Radio Info display items in both button/scroll and menu modes. If disabled, the Radio ID
menu mode will display a blank line.
Note In dual control configurations (front mount radio with remote control unit), the power
switch at either control point can be OFF for power to turn OFF.
4.1.1.1 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 5.6), 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 5.3 on page 25), 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 mobiles with Viking Series Remote Control Heads. The
minimum volume setting has no effect on the volume of a pre-ES Series model remote
control head using an internal speaker whether it is attached to a pre-ES Series or an
Viking Series mobile radio.
4.1.1.2 Standard and Soft Power Down
To turn power off, press the ON-OFF/Volume knob.
A soft feature can be programmed to prevent radio power from being turned off by
accidentally pressing the on-off/volume knob. If the user presses the ON-OFF/Volume
knob, “POWERDOWN” will be displayed. 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.
