2.6 Scan
With the Scan feature, the radio can detect the communication activities on other
channels and select the channel for staying on according to the scan result. After
you start the scan of the radio via the programmable key or radio menu, the radio
will scan the activities on the preset channels circularly in order. When detecting
some activities that you are interested in on a channel, the radio will pause on that
channel until the Hang Time is up. Then the radio will continue detecting the
channels repeatedly until it quits the Scan mode. Hytera DMR scan supports both
digital channels and analog channels.
The Scan feature shall be activated in the following conditions:
The “Scan List” parameter in “Channel” cannot be set to “None”;
There are at least two channels in the Scan List, or you cannot activate the
feature.
When the conditions above are all fulfilled, you can also select the Auto Scan
feature for a channel, so when you switch the radio to the preset channel, the Auto
Scan will be activated. When scanning, the radio will stay on an active channel for
some time before it scans another channel, so as not to miss the activity detection.
You can set the time for staying (Hang Time) via the CPS.
There are some scan statuses:
Scan: The radio detects the activities on the channels, listed in the Scan List, in
order.
Stay: If there are some communication activities that satisfy the requirements
on staying on a channel, the radio will stay on that channel until the Hang Time
is over. Then it will continue to scan other channels.
Sweep: When the radio stays on a low-priority channel, the priority channel
Sweep Time will alert the radio to detect the high-priority channel. When there
is active signal detected on the priority channel, the radio will jump to it
immediately; in case of no signal detected, the radio will stay on the current
channel.
Suspend: During scanning the analog channels, you can enter or quit this
status by pressing the programmed
Monitor
key or
Squelch Off
key. In this
status, the radio can sweep the priority channels.
Terminate: When the radio receives the special code such as the emergency
code, it will terminate the scan. It will stay in this status and not scan or sweep.
Off Hook: This status occurs only in mobile radio scan. The scan process is
affected if the microphone is off the hook.
