3-4 Viking Portable 600 Radio Operating Manual
General Operation
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 Portable radios.
The relative volume level can be determined by the position of the index on the volume
knob or by a reference signal as follows:
• If a key press tone is enabled, a short tone sounds when a key is pressed. Tones and
audio can differ depending on how it is programmed.
• If a conventional channel is selected and the Monitor option button or menu parameter
is programmed, pressing that button unsquelches the receiver and either voice or
background noise is heard (see Section 5.2). If a SmartNet/SmartZone or P25 Trunking
channel is selected, the receiver cannot be manually unsquelched.
3.2 Clock
The Viking Portable Clock feature allows the user to display and set the date and time in
the desired format on the radio screen. This feature uses the hardware clock so that updates
do not impact radio timing.
On the radio, you can activate the “Set Time” feature, allowing you to do the following:
• Set time format (AM, PM, 24HR)
• Set time (hour, minute)
• Set date format (YMD, MDY, DMY)
• Set date (year, month, day)
You can use the up/down buttons on the front of the radio to modify the fields. F2 (Menu)
advances the cursor and F1 (Clear) backs up the cursor.
You can also activate the “View Time” feature, displaying the month, day, year, and the
time, including seconds. Since this feature can be used as a timer, it does not timeout after
a period of time to return to normal zone/channel display. However, press any button to
exit the feature.
