BC346XT Search for...


To determine whether the information on this page applies to your scanner, see the tags at the bottom of the page.

Use this menu to start a search, to change the options for the three different types of searches, and program the 3 search keys.

Service Search

Start a search of one of the 11 preset service bands. Choose from Public Safety, News, HAM Radio, Marine, Railroad, Air, CB Radio, FRS/GMRS/MURS, Racing, FM Broadcast, or Special .

Edit Service

This menu lets you change the default settings for the 11 preset service bands. Select the service you want to edit from the list, then set the following options:

Set Delay Time

Set the number of seconds the scanner should wait after a transmission stops before moving on to the next channel. Select 0, 1, 2 (default), 5, 10, or 30 seconds.

To have scanner leave the channel after a designated number of seconds whether the transmission stops or not, select one of the negative values. Choose -10 seconds to have the scanner leave the channel after 10 seconds even if the transmission is still going on; choose -5 seconds or -2 seconds to have the scanner leave after 5 seconds or 2 seconds, respectively.

Set Attenuator

Turn on attenuation to reduce the signal strength by 20 dB. You can turn on attentuation for individual frequencies and channels or for entire sites. If you turn on attenuation for a site, all frequencies within that site will be attenuated.

Custom Search

Start a search of the 10 custom search ranges.

Edit Custom

This menu lets you program the ten custom search ranges. Select the custom search you want to edit from the list, then set the following options:

Edit Name

Enter a name or edit the existing one. Names can be 16 characters long, and they can contain upper and lower case letters, punctuation, and spaces. Turn the SELECT-VOLUME-SQUELCH knob on the handheld scanners or the SCROLL / FUNCTION knob on mobile scanners to choose the character you want, then press 6 (right cursor) to move the cursor to the next character.

Edit Srch Limit

Change the range of frequencies covered by this custom search. The scanner prompts you to input the lower frequency limit and then the upper frequency limit.

Set Delay Time

Set the number of seconds the scanner should wait after a transmission stops before moving on to the next channel. Select 0, 1, 2 (default), 5, 10, or 30 seconds.

To have scanner leave the channel after a designated number of seconds whether the transmission stops or not, select one of the negative values. Choose -10 seconds to have the scanner leave the channel after 10 seconds even if the transmission is still going on; choose -5 seconds or -2 seconds to have the scanner leave after 5 seconds or 2 seconds, respectively.

Set Modulation

Select what type of modulation the scanner should use for this frequency or channel. (Only the modulation types available for this frequency or channel are displayed.)

Auto The scanner uses the default modulation type for this frequency's band.
AM The scanner treats the frequency as an AM band.
NFM The scanner treats the frequency as a Narrowband FM band.
FM The scanner treats the frequency as an FM band.
WFM The scanner treats the frequency as a Wideband FM band.
FMB The scanner treats the frequency as an FM broadcast band.

Set Attenuator

Turn on attenuation to reduce the signal strength by 20 dB. You can turn on attentuation for individual frequencies and channels or for entire sites. If you turn on attenuation for a site, all frequencies within that site will be attenuated.

Set Step

Select the number of kHz between each channel. Choose 5.0, 6.25, 7.5, 8.33, 10.0, 12.5, 15.0, 20.0, 25.0, 50.0 or 100.0 kHz. Select Auto to use the default step for this band.

Set C-Ch Only

If you set C-Ch Only Mode to On, the scanner will only search for control channel data. If it detects such data it will stop on the control channel and display channel activity for the found system. For Motorola systems, it will try to follow voice channel traffic using the Motorola Band Plan you select in the next setting. It will also display the name of the found system if the system's ID matches a known system.

Set MOT BandPlan

If this custom search is a Motorola system, you need to select a band plan, just like you do when you program a Motorola system for scanning. See Edit Band Plan for more information.

Search and Store

Search a stored system and save the frequency information of any active channels.

Set Search Key

The scanner has three one-touch search keys (number keys 1 , 2 , and 3 ) that you can assign to any saved search range.

  1. Select the search key you want to program ( Search Key 1 through Search Key 3 ).
  2. Select the search range you want to assign to this key. The search range can be a service search, a custom search, a tone-out search, or a band scope search.
  3. Press YES to confirm the selection.

Once you assign a search range to a key, you can start the search just by pressing and holding the appropriate key.
