Question about Plantronics Calisto Pro Series Cordless Landline/VoIP Phone

5 Answers

Display on handset of Calisto Pro Series D150 is blank

The display on the handset of my phone has suddenly gone blank, so I am unable to see menu information, etc., (including whether the phone is muted or not). It worked correctly yesterday and didn't when I answered a call earlier today.

    The handset has power; the display screen lits up but none of the commands, etc., are displayed. If I click the menu button, I get a series of dark lines and colors that look almost like a huge spreadsheet has been compressed onto the screen (though that obiously isn't the case); nothing is legible and using the up and down arrows cause it to get darker or light, but nothing else ever appears. When I click the END button, it goes blank again.

    Since the phone has power and removing/replacing the battery didn't help, this seems like a logical explanation of the problem. I am replacing the phone.
    Thank you.

Remove the battery from the device for sometime.also clean the socket where the battery is inserted and then reinsert it again and check out.if still the same problem the battery most probably needs replacing.still get it checked by a mechanic it can be internal circuit problem also.

The problem is the LCD display has burned out, has the phone been dropped? in any event you will find it is cheaper to replace the phone than fix it.

Handset display says "Connecting" I can't deregister. How can I get the handset to display "not registered"?


The procedures to deregister are, of course, specific
to each make and model number of cordless phone.
All of them are a LOT more involved than simply
removing the battery.

For some AT&T, VTech, Uniden, & GE model numbers
you might try the following:
=====================================
For many AT&T models it is simple:
1. When the handset says "Connecting..."
enter *331734 [menu]
it will soon (chirp) and display "Not registered"
=====================================
For many VTech models it is a bit more involved:
1. Start by taking off the battery compartment cover.
2. press [menu]
3. scroll up/down to "Settings"
4. enter * 7 8 9 0 #
5. if display reads "Test Base",
scroll to "Test Handset", press [select]
scroll to "next page", press [select]
6. scroll to "Register Clear?", press [select]
7. display asks "Confirm?" or "Register Clear??",
press [select]
8. display reads "Ok" (chirps), press [ off ]

9. UNPLUG THE HANDSET BATTERY
(this is why the cover is off)
10. Wait ~30 seconds, re-connect the battery &
replace the cover
11. display reads "Not Registered"
=====================================
For many Uniden models:
1. Press and hold the [END] and [ # ] keys at the
same time, after a few seconds the display reads
2. "System Reset, Deregister Handset"
3. scroll to "... Base Unavailable"
press [SELECT]
4. Handset (chirps)
press [END]
5. display reads "Not Registered, Place in base..." =====================================
For some GE models:
1. press "program[mute]"
2. scroll to "Handset Setup" press "program[mute]"
3. scroll to "Deregistration" press "program[mute]"
4. scroll to "Yes" press "program[mute]"
5. display reads "Not Registered"

=====================================
Once you have the handset displaying "Not Registered"
you can follow the User's Manual instructions to register
the handset.

The model number for your cordless phone is shown on
a small sticker underneath the battery in the handset --
enter this number at www.manualslib.com to get a free
copy of the User's Manual if you need it.

Good luck!

Led display does not work on my panasonic 5.8Ghz phone KX-TG5632


I just spoke to Panasonic Tech Support about the LED screen being blank. FYI its blank on both my handsets - one which I never even use. He made me do a few button presses, etc but nothing worked. So he tells me I have a "loose connection on the LED" so I must have dropped the phone or something. I said NO, I never dropped the phone, and one of the handsets I never even used - and its happening on that one too. So bottom line you have to take it to a Panasonic repair center at your own expense if its over the one year warranty - for what I personally think is a flaw on their phone design. I think after so much time the LED screen just goes away...since its happening on both handsets, and neither of them were dropped. Its a shame because the phone works fine, but I need the LED screen for the mute button, etc. So my solution for you is to stay away from Panasonic phones and the lame customer support, and go buy a different brand.

Uniden TRU888 5.8 Digital Phone Display no longer lights up


I purchased this model phone as a refurb item and also had display blanking out issues. Mine related to a problem with the battery, which new batteries fixed. Try swapping the batteries between handsets and see if the fault moves to the other handset, which will prove if it is a battery problem. Otherwise, it would seem to be an internal fault in that handset. Try and arrange repair/replacement from the seller.

I know this should be a MUCH more techie answer, but have you tried just asking a nearby Mexican to help you? Just a thought.....

What happens instead?

2. Press the mute/menu OK button to go to the main menu.
3. Press CALLER ID-VOLUME ( 6 or 5) button to scroll to HANDSET SETUP.
4. Press mute/menu OK button to confirm and you may program the following items: Language, Handset Name, Ringer Tone, Ringer Volume, VIP Melody, Key Tone, Set Day/Time, Equalizer, Area Code, Tone/Pulse, Registration, Deregistration and Default Setting.
NOTE: During programming, you may press the END/cancel button at any time to exit the sub-menu and return to the menu.
Language
From the Handset Setup Menu:
1. Press the CALLER ID-VOLUME ( 6 or 5) button to scroll to the SET LANGUAGE sub-menu.
2. Press mute/menu OK button to enter the menu. SET LANGUAGE 1ENG 2FRA 3ESP shows in the display.
3. Use the touch tone pad on the handset to select 1ENG, 2FRA, 3ESP, or use the CALLER ID-VOLUME ( 6 or 5) button to scroll to the desired language. English is the default setting.
4. Press the mute/menu OK button to save your selection. You will hear a confirmation tone and the selected language shows in the display.

Unable to register handset TWX955 Series


I have a TRU9585 Base.

ATT 5840 Base reset code/procedure


document.write(parent.prscreen) Try this to get it working. Relocate the handset(s) closer to the main base.

Check for any lights on the base including charge, intercom, and channel lights (if applicable to the model).

Re-cradle the handset on the base for 15 seconds. Lift the handset and press 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.

Try to de-register the handsets by following the steps below:

1. Using the soft keys on the base located below the base screen, press MENU
2. Press the down arrow once until BASE SETTINGS is highlighted.
3. Press the OK soft key.
4. On the base, press MUTE 3 times and FLASH twice. This will

2. Using the soft keys on the base located below the base screen, press MENU.
3. Use the up or down arrow keys to select DISPLAY BASE ID.
4. Press OK. The base screen will display the 15-digit Base ID

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.

I would assume this could have been a product that was returned to the company that you purchased it from. Follow these instructions. 1. 1. Disconnect power from the base by pulling the plug out of the back of the unit. 2. Press and hold the Page button and while holding the Page button reconnect the power. 3. Continue to hold the Page button until the charge/in use light flashes rapidly. 4. Release the Page button. 5. Press and release the page button on the base once. All handsets are de-registered and HANDSET NEEDS REGISTRATION shows in the display. Then From the Handset Setup Menu: 1. Press the caller ID-volume ( 6 or 5) button to scroll to the REGISTRATION sub-menu. 2. Press the mute/program button to enter the menu. REGISTRATION 1YES 42NO - - -shows in the display. The default setting is 2NO. 3. Use the touch-tone pad to select 1 for YES or 2 for NO. Or use the caller ID-volume ( 6 or 5) button to scroll to 1YES or 2NO. 4. If you select YES, press the mute/program button. HOLD BASE PAGE FOR 5 SECONDS, THEN PRESS HANDSET PROGRAM shows in the display. (Your handset should be held near the base during registration process.) 5. Press and hold the page button on the base unit until the charge/in use indicator flashes. Press the handset mute/program button. REGISTERING shows in the display. HANDSET X REGISTERED shows in the handset display, where X is the handset number. You may now rename your handset. (Refer to Step 3 & 4 of Handset Name Section) NOTE: IF you are re-registering the handset through the handset menu; to rename your handset you must go to the Handset Name Section and start from the beginning step. I understand that you have tried the registation process. Sometimes with electronics, you have to start from ground 0, before it will work correct again. If there are further questions or comments, please post here. Please rate this solutn through fix-it. Thank you
