Viking Portable 600 Radio Operating Manual 3-13
General Operation
• If the radio has Soft Power Down mode enabled and the radio gets inhibited, the radio
will ignore the Soft Power Down settings and power off normally.
• Downloading a codeplug with Armada will uninhibit a radio
• Inhibit is a global setting so you can inhibit a radio with one method and uninhibit it
using another.
3.8 Setting Squelch
The user can program a menu item, or function button, for squelch adjust. While on a
conventional analog channel without emergency or scan active, the user can select the
programmed button or menu item for squelch adjust. The current squelch setting will
show on the display. Using the up and down buttons on the portable radio, the user can
adjust the squelch setting to a desired level from -7 to +7. Increasing the value towards +7
causes the squelch to open sooner for weaker signals while decreasing towards -7 has the
opposite effects. Pressing the select button will store the new squelch setting and return
the user to the main display.
The squelch level is preset and may not require readjustment. However, if the squelch
threshold needs to be changed on a conventional analog channel, it can be changed in the
same way as though using keypad programming if available. The squelch level is preset
during alignment. If the keypad programming feature is available (see Section 5.14), the
squelch threshold can be changed by the user on each conventional analog channel.
Note The Keypad Programming feature is available to Federal Government users only.
3.9 Transmit Disable
Transmitting can be disabled on each conventional, SmartNet, SmartZone, and P25
Trunking 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. This is
programmed for each radio.
