Dual Watch - Vertex Standard VX-5500 Operating Manual

Channel Scan ( SCN )
The Scanning feature is used to monitor multiple signals programmed into the trans-
ceiver. While scanning, the transceiver will check each channel for the presence of a
signal, and will stop on a channel if a signal is present.
To activate scanning:
¦ Press the assigned PF button of the "Scan" momentarily to activate scanning.
¦ The scanner will search the channels, looking for active ones; it will pause each
time it finds a channel on which someone is speaking.
To stop scanning
¦ Press the assigned PF button of the "Scan".
¦ Operation will revert to the channel to which the CHANNEL selector knob is set.
Note: Your dealer may have programmed your radio to stay on one of the
following channels if you press the PTT switch during scanning pause:
r Current channel ("Talk Back")
r "Last Busy" channel
r "Priority" channel
r "Home" channel
r "Scan Start" channel

Dual Watch

The Dual Watch feature is similar to the Scan feature, except that only two channels
are monitored:
r The current operating channel; and
r The "Priority" channel.
To activate Dual Watch:
 Press the assigned PF button of the "Dual Watch".
 The scanner will search the two channels; it will pause each time it finds a chan-
nel on which someone is speaking.
To stop Dual Watch:
 Press the assigned PF button of the "Dual Watch".
 Operation will revert to the channel to which the CHANNEL selector knob is set.
Call/Reset
When this feature is programmed and a selective call has been received, momentari-
ly press the assigned PF button of the "Call/Reset" to reset the flashing indicator
and mute the receiver, otherwise press the assigned PF button of the "Call/Reset"
to sent your radio's identification code (ANI) to the dispatcher.
Noise Blanker ( NB )
Because local noise can be particularly troublesome in the VHF Low-Band fre-
quency spectrum, the Low-Band version of the VX-5500 includes a Noise Blanker
feature, which may be toggled on and off by pressing the assigned PF button of the
"Noise Blanker" for the appropriate length of time.
