No long distance

Several things can go wrong. Do they need to dial an extension to access an outside line? Make sure they know this. Also, make certain to remove any area code in the menu settings. The phone could be trying to make a call, yet it dial the area code each time and screws up the PBX, so no outside line. There are more possibilities, but they require on site tests.

1. Remove the AC adapter plug from the back of the base unit (not from the wall); leave tel cord connected.

2. While holding down the "set code" button under the cassette lid, plug the ac adapter back into the base. The screen will then display some numbers (110) etc.

3. Hold down the HANDSET keys 1 and 2 simultaneously and then press the speaker button on top within 20 seconds.

4. Press any 3 digits on the handset i.e. 1-2-3.

5. After hearing a BEEP from the handset and base, press 2 on the handset. The base should then say "twenty-five", and the handsets will beep, confirming the new security code is enabled. Press talk or speaker on handset to confirm communication.

6. The time/day stamp and remote access code will be cleared.

7. Best to do this with the answering mach turned off.

8. Restart this procedure if anything goes wrong (may hear a series of error beeps).

I saved my manual and in it I had a fax Casio sent me with these instructions (i had this prob a few times years ago). Good luck!

We have a phillips se155 phone with answering machine, but when anyone tries to leave a message it says there is no more room. However I have deleted all messages on it. I would be glad of any advice because I have lost the booklet that came with the phones.

Well technically it's not on thier end. Let's remember that a fax uses a normal home style phone line.
So ask yourself these questions.
#1 Do I have long distance service on this phone line?
#2 If I do have long distance service do I need to do any kind of special dialing sequence to access long distance? Like a 9 or an 8 or any other number before dialing outside of your local area.
In some cases( businesses usually) a special code needs to be entered after dailling the number.
Most fax machines have a hansdset on them. Do this simple test. Lift the handset and dial a known long distance number and listen to what the operator message says. If all else fails call your phone company and ask them if this line has long distance capability.

I unplugged the base unit and took a battery out of the handset. I then put the battery back in the handset and replugged the base unit. This corrected the problem.

Check the phone line with a regular phone.

Unplug the AC adapter from the main base unit and take out the battery from the handset. Leave it unplugged for 15 seconds. Plug the handset battery in and re-cradle the handset. Plug back the AC adapter in and wait for 15 seconds.

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

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.

The solution for the base (not the handset) is to press and hold for 2 seconds the "Skip" button (it's marked with ">>").
