Binatone 1910 flashing not registered to base


Registration:
Instructions if you need to register handsets to the base:
You can register additional handsets to have up to five handsets per base unit, with each handset's number (1 to 5) shown on its display.
1. Press and hold <PAGE> on the base station for more than five seconds to put the base station into registration mode. (Note: there is no feedback to know it is in reg mode.) It will stay in registration mode for about 1 minute. So complete following sequence within this time. (It helps if handset is kept very near to the base during this).
2. Press <MENU> and <UP/DOWN> on the handset to select REGISTRATION.
3. Press <OK> and you are requested to enter the 4-digit system PIN.
4. Enter the 4-digit system PIN.
5. Press <OK> to confirm, and the display will show SEARCHING. If the handset registration is successful, you will hear a confirmation tone and the <antenna icon> will stop flashing. This may take a short while. The handset will automatically be allocated the next available handset number. This handset number is shown in the handset display in standby mode. If thehandset registration is unsuccessful, the <antenna icon> will still flash and the display will return to ' REGISTER', so you will need to repeat registration process.

Answering machine on light keeps flashing but does not turn on unit


The headset(s) and the base station need to be re-sync.

Check the bottom contacts (base and headset) and let them sync (3+ minutes) OVER-NIGHT if the headset are low on battery.

This will sync the security code.

Cordless phone system does not record caller IDs


I can only tell you that I had similar problems with my Uniden system. My solution, after much frustration, was to buy a $25 AT&T answering machine and add it to the system. I then turned off the Uniden recording capability and for the last two years have been very happy. I use Firefox which has an extension (found as an add-on) called PriceBlink. Once I brought up the web page describing the answering machine, PriceBlink notified me that the best price was, not amazingly, was in Amazon dot com. PriceBlink also shows the price for S&H. If you use Chrome there is a similar extension whose name I have forgotten, but it is equally effective. I won't use IEx, so if you're looking for a best price and not using Firefox or Chrome I can't tell you how to find a best price, but just google "Telephone Answering Machine" (with the quotation marks) and see what's there. There aren't a lot of them - they're a dying breed. I've given up on Uniden. One of the satellite phones stopped working after about 18 months. I don't buy extended warranties, so that one was trashed.

CL code


My phone was also flashing CL and the 0, after a power outage. After I set the date and time it was fixed. Press the flash button on the handset and use the caller ID buttons to set AM or PM; use the numbers to input the correct time. Then press #. Repeat for setting the day and press # again.

Other products that use the 5.8GHz band can interfere with the use of this phone. These products or equipments include: radio towers, page towers, cellular Phones, other 5.8GHz cordless phones, intercoms, or monitors. If any of these are in the area, they may interfere with the performance of the phone. Try relocating the phone.

Video displays, Televisions or Personal Computers can cause
interference on the phone if it is plugged in electrically with one of this equipment (typically on a power strip or extension cord). Please relocate the phone to an AC outlet without any other major appliance plugged in.
You can also relocate the base to another room.

Relocate the phone out of the kitchen area. Appliances may cause interference.

If the charge light does not remain on, clean the handset and base charging contacts using a pencil eraser. If it comes on after cleaning the contacts, you may need to charge the unit for 10 hours.

Make sure that the AC power cord is securely plugged into the base. If unsuccessful, plug the unit into a different known working outlet or turn on the switch on the power strip.
