Uniden UBC780XLT manual

Enter Lock - This is the term used for locking the keypad. This prevents accidental re-programming of channels and talkgroups entered into memory. The default setting is off.

When ENTER LOCK is enabled, the following functions will be disable:

•Enter or modify the Channel frequency

•Enter or modify the Tone information

•Enter or modify the Trunking ID. ( this can be modified through the menu screen.)

I-Call- Most communications within a trunked system are group calls where one unit (such as a dispatcher) communicates with all the units within her group (all the patrol vehicles on the east side of town, for example). The units within this group comprise what is typically known as a talkgroup. There are some communications which are direct unit-to-unit conversations where one individual converses with another individual. The call is initiated by a radio and is directed to another single radio. Within the system, no one outside of these two users hears the conversation. This call is referred to as I-Call.

Key Beep - This is another term for the tone you hear as a keypad acknowledgement beep. The default setting is on. If you have turned the Key Beep off, you now have a silent keypad. You will not hear a tone each time you press a key.

PC Control - This term is associated with the ability to program frequencies and other useful information via a computer by means of the Uniden national database or third party software. You can change the transfer speed on the scanner needed to be compatible with your PC. (See page 55)

Scan List - When you designate a bank to be a trunking bank, your scanner sets up 10 Scan Lists, which are simply list of your favourite IDs. Each list can contain up to 10 IDs, so you can store a total of 100 IDs for each trunk bank. These lists are designed to help you organise the trunking system users into categories.

Screen mask - Screen Mask reduces the amount of information that appears on the display. Alpha tags that you have set for a channel along with a few function icons will appear only on the display. This mode is particularly useful in public safety vehicles where that are already overloaded with information. Screen Mask does not work in Search mode.

Status Bit - This term refers to Motorola Type II systems. There is a method by which special types of communications utilise unique talk group numbers. For example, if all emergency calls are set to occur on a specific talk group number then you will not miss the transmission even if you have not programmed all the talk group numbers. With the Status Bit on and you have programmed the unique number, then you don’t have to worry what the rest of the groups numbers are. The topic of interest will be picked up.

Talkgroup - A group of users within a trunked system that communicate with one another.
