    • If caller ID isn’t working it’s probably because there is some static or noise on the line. Caller ID signal is very susceptible to noise.

      If only a cordless handset is not showing caller ID but the base unit (and / or other hard wired phones) is showing caller ID correctly then there could be noise or loss of information in the radio signal. I have seen cordless phones that otherwise appear to work OK stop ringing because the radio signal was just poor enough to block the signal telling the handset a call was coming in.

  1. Hi sir,
    My panasonic cordless phone model number KX-TG3521bx is locked and now he want to password for use but i dont know the pasword of my cordless phone .so tell me how can i do for the sulotion of my problem..plz helpe me im very worried about that problem.

  2. calls coming in , I can hear them but they cannot hear me, I have put new batteries in but still no difference?

  3. I got a cordless fone and everytime i charge it it wl.work for 1 day then goes blank and shows recharge.for 7 hrs…have changed batteries given it to the service center both in sharjah and mumbai but nothing helps…havent even used it to its full capacity.

    • What model phone is this? How long are you talking on the phone? Is this just off the charger all day and maybe a few calls or are you taking many calls? Some phones have 2-cell batteries (2.4v) and some have 3 cells (3.6v). The 2-cell batteries do not last as long and tend to suddenly drop out toward the end of their charge where 3-cell batteries will die slowly. Another thing to consider is how far away from the base you are. The radio module uses the most power and if the signal is weak the phone may use more power to boost the radio.

  4. I found wax/play dough stuck under the phone handset charging prongs…..just a little bit. I cleaned it out with dry Q-tips and also wiped out the charging bases and cleaned all handsets also. I changed out the Ni-MH rechargeable batteries to the new eneloop batteries I got after charging fully outside. Hope it works. I will get back to you guys. Otherwise I will just buy the latest phone.

  5. My panasonic phone display is blank after 3 years …
    but i can hear and attend calls
    there is no display ..only back light

    • Sounds like it could be the power adapter. The old heavy brick power adapters almost never break but the new small and light switching adapters fail a lot more often. Sometimes they are dead, sometimes they put out only a little power (maybe lighting up LEDs but not much else) and sometimes they blink on and off.

  6. My panasonic KX-TG7642 M series phone keeps resetting every 20 seconds. The base unit goes blank and starts all over again. I am going mad over this. The phone used to work fine for couple of years. Suddenly one fine day it started resetting. Could you please help?

    • It sounds power related. The power adapter may be bad. Check to see if your charger stand power adapter has the same power output as the base. If it does, try swapping them.
