4-10 Viking VM600 Mobile Radio Operating Manual
General Operation
A “Favorites” button in the Viking VM600 allows the user to add channels to the Favorite
Zone. If The Favorite Zone is enabled, the user has the ability to change the channels that
are in his favorites list, as follows:
1 Select the zone / channel to be placed into Favorites, using the zone/channel selectors.
2 Press the “Favorites” button (the radio remembers the current zone/channel).
3 Turn the Selector knob to the location (1-16) where you want to store this favorite. The
radio will automatically start at the first unprogrammed channel and if all channels are
programmed, the radio will start at Channel 1.
4 To store the new channel to the favorites list, press the Select button. The radio will
remain on the channel that was just added to the Favorites list.
5 To exit without saving, press the programmed Favorite button (the button you pressed
to enter this mode).
6 Upon exit, the radio will remain on the channel that was just added to the Favorites list.
4.1.7 Setting Squelch Control
This radio does not have a squelch control. The squelch level is preset and usually does not
require readjustment. However, if the squelch threshold needs to be changed on a
conventional analog channel, it can be changed using keypad programming if available
(see Section 5.17 on page 36).
Note The Keypad programming feature is available to Federal Government users only.
4.1.8 Transmit Disable
Transmitting can be disabled on each conventional, SMARTNET, SmartZone, and P25
Trunked channel so that the channel is monitor-only. When transmitting is attempted on a
receive-only channel, “RX ONLY” is displayed and an error tone sounds.
4.1.9 Operation At Extended Range
When approaching the limits of radio range, the other party may not be able to hear your
transmissions and there may be an increase in background noise when messages are
received. You may still be out of range even though you can hear a message. The reason
for this is that the signal you are receiving is usually transmitted at a higher power level
than the one transmitted by your radio. Communication may be improved by moving to
higher ground or away from shielding objects such as tall buildings or hills.
