Radio Wide Features
Home Zone and Home Channel cannot be set to “Selected” simultaneously. The same 
applies for Home Zone 2 and Home Channel 2. If Home or Home 2 is set to “Selected,” 
then Home Channel or Home Channel 2, respectively, will populate with channels 1 to 
256.

Power Output Select
Each conventional channel, SMARTNET/SmartZone, and P25 Trunking system can be 
programmed for High, Low, or Switchable transmit power. If Switchable power is 
programmed on the channel or system, the Hi/Lo Power option switch can then be used to 
select high or low transmitter power. All models support switchable power. The low 
power level is typically 15 watts and the rated power output level of the radio at the high 
power level is typically 25 - 30 watts, depending on frequency band.
Pressing the Hi/Lo Power switch toggles the power setting. The new level is flashed in the 
display when this switch is pressed as “HI POWER” or “LOW POWER”. If selectable 
power is not permitted on the current channel or system, the fixed power level is flashed 
and no power change occurs. The selected power level is permanent until it is manually 
changed again. The power levels are set at the factory or when the radio is tuned using the 
Viking Tune™ software.

Alert Tone Select
The various alert tones that sound are described in Section 9.1. These tones can be enabled 
and disabled if the TONE option switch is programmed. To turn all tones OFF, press this 
switch and “TONE OFF” is displayed. Then to turn all tones on again, press it and “TONE 
ON” is displayed. If this switch is not programmed, tones are fixed in the ON or OFF 
condition by programming. Alert tones can be disabled depending on programming. If the 
Surveillance mode is programmed (see following), tones are totally disabled.
The Alert Tone volume can be adjusted relative to the volume control setting. This is done 
by programming and also by the user if the Alert Tone Volume option switch is 
programmed. Relative levels of –170 to +170 can be set with “0” the default setting. The 
range is divided into the number of volume ticks set in “Volume Ticks”. For example, if 
“Volume Ticks” is 10, the tone adjustment on the radio will go from 1 to 10. A minus 
value decreases the tone volume and a plus value increases it. The user adjusted level 
permanently overrides the programmed level if applicable.
