Multi-Channel Monitoring
The scanner can check multiple tone combination for channels that have the same settings for frequency,
Modulation and Attenuator.
For example, the scanner can check tone combination from CH 1 to CH3 at the same time when you
program the scanner with the following settings.
Frequency (MHz)
Modulation
Attenuator Tone A (Hz)
Tone B (Hz)
CH 1
137.0000
Auto*(NFM)
Off
1000.0
2000.0
CH 2
137.0000
Auto*(NFM)
Off
2200.0
3200.0
CH 3
137.0000
NFM
Off
1500.0
2500.0
CH 4
137.0000
NFM
On
1800.0
2800.0
CH 5
137.0000
FM
Off
2000.0
3000.0
CH 6
138.0000
Auto*(NFM)
Off
1000.0
2000.0
*Modulation setting "Auto" follows the initialization of Band Coverage. However, when modulation of the
frequency in
Band Coverage
is not FM or NFM, it is forced to FM. And
͞
Auto

is compared as NFM or FM
with other channel
͛
s setting.
*The scanner detects the Tone on the channel that its number is the smallest if you set the same tone in
multiple channels.
While Tone-Out Standby Mode for Multi-Channel Monitoring, the scanner switches the channel display
every 2 seconds. But the scanner checks all Tones for Multi-Channels simultaneously.
When one of the tone combinations is detected, it goes to Tone-Out Hold Mode.
