Viking Portable 600 Radio Operating Manual

3-3

Settings retained through power cycle of the Viking Portable radios include. 

The volume level is adjusted by the top panel volume control knob or by option buttons 
programmed for the Up/Down volume function. When the buttons are used, the volume 
control function of the knob is disabled (it is still used to switch power). Volume buttons 
may be used instead of the knob, for example, if accidental turning of the volume knob is 
a problem.

When the volume control buttons are used, the number of steps (ticks) required to change 
the volume from the minimum level to maximum level is programmable for 2-50. For 
example, if “20” is programmed, there are 20 adjustment steps from minimum to 
maximum volume. Only one volume control button can be programmed if desired and 
wrap-around then occurs after the maximum or minimum level is selected.

The radio can also be programmed so that volume control is also be disabled by the 
Keypad Lock feature.
