Programming a Hybrid System A Hybrid system is simply a Type I system with some blocks designated as Type II blocks. To program a Hybrid system, follow the steps listed in Programming a Fleet Map in the previous section. However, if you want a block to be Type II, select Size Code S-0. When you begin searching a trunking bank with a Hybrid Fleet Map, you will see both types of system IDs. That is, Type II IDs usually appear as an even number without a dash; Type I IDs appear as a three or four digit number, followed by a hyphen, followed by a one or two digit number. See page 61 for more information. 12345678 910BANK TRUNK 12345678 910BANK TRUNK 53
Care and Maintenance General Use Turn the scanner off before disconnecting the power or replacing the batteries. Always write down the programmed frequencies in the event of memory loss. If memory is lost, simply reprogram each channel. The display shows 000.000in all channels when there has been a memory loss. Always press each button firmly until you hear the entry tone for that key entry. Location Do not use the scanner in high-moisture environments such as the kitchen or bathroom. Avoid placing the unit in direct sunlight or near heating elements or vents. If the scanner receives strong interference or electrical noise, move it or its antenna away from the source of the noise. If possible, a higher elevation, may provide better reception. Also try changing the height or angle of the antenna. Cleaning Disconnect the power to the unit before cleaning. Clean the outside of the scanner with a mild detergent. To prevent scratches, do not use abrasive cleaners or solvents. Be careful not to rub the LCD window. Do not use excessive amounts of water. 54
Repairs Do not attempt any repair. The scanner contains no user serviceable parts. Contact the Uniden Customer Service Center or take it to a qualified repair technician. Birdies All radios can receive “birdies” (undesired signals). If your scanner stops during Scan mode and no sound is heard, it may be receiving a birdie. Birdies are internally generated signals inherent in the electronics of the receiver. Press Oto lockout the channel, and then press Sto resume scanning. 55
Troubleshooting If yourBC 235XLTis not performing properly, try the following steps. Problem Suggestion Scanner won’t work. 1. Check the connections at both ends of the AC Adapter. 2. Turn on the wall switch of your room. You could be using an outlet controlled by the wall switch. 3. Move the AC Adapter to another wall outlet or replace the battery pack. Improper reception. 1. Check the antenna connection or move and reposition the antenna. 2. Move the scanner. 3. You may be in a remote area which could require an optional multi-band antenna. Check with your dealer or local electronics store. Scan won’t stop. 1. Adjust squelch threshold - refer to page 15, Setting the Squelch. 2. Check the antenna connection. 3. Check to see if many of the channels are locked out. If so, the scanner has less chance of finding an active channel. 4. Review each channel’s frequency to see if it is still stored in memory and is correct. 5. It’s possible that none of the programmed frequencies are currently active. Scan won’t start. 1. Press the Skey again. 2. Adjust the SQUELCHcontrol. 3. Check to see if all channels are locked out. Weather Scan won’t work. 1. Adjust squelch threshold - refer to page 15, Setting the Squelch. 2. Check the antenna. 56
If you experience difficulty while inTrunkTracker™mode, try the following steps. Problem Suggestion Scanner won’t track the trunked system.1.
