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)
CH 1 137.0000
CH 2 137.0000
CH 3 137.0000
CH 4 137.0000
CH 5 137.0000
CH 6 138.0000
*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.
