Setting the Modulation Mode

2:SCAN OPTION → 1:CONVENTIONAL → Channel No. → 7:MODE

Radio transmissions are modulated in several different ways. The BC796D is able to demodulate the most common transmission types. Your scanner has the most common modulation mode preset for each band, so you seldom have to change this option. However there are occasional services that use a modulation mode that is not standard for that band.

1:AM

Amplitude Modulation

2:FM

Frequency Modulation

3:WFM

Wideband FM

4:NFM

Narrowband FM

Setting Priority Channels

You can set one conventional channel in each bank as a priority channel. When you turn on the Priority Scan option (see “Priority Scanning”), the scanner automatically checks these channels every 2 seconds to see if there is activity. If there is, the scanner immediately switches to the priority channel.

Notes: • The scanner does not check priority channels in locked-out banks.

•The scanner does not check priority channels if the channel is locked out.

By default, the first channel of each bank is set as priority. To change the priority channel:

1.Manually select the channel you want to set as priority.

2.Press and hold PRI for 2 seconds. The scanner beeps and the new priority assignment is made.

Note: To program priority talkgroup ID’s for trunk scanning, see “Setting Priority Talkgroups.”
