Question about Sony SPP A940 Cordless Phone (SPP-A940)

1 Answer

In Use LED flashing constantly

Recently moved: set up phone and plugged in power, set handset on base and the "Charging" LED lights up (as expected) and "IN USE" LED flashes constantly. Normally, the "IN USE" LED flashes four times when the handset is replaced. There is no dialtone, no indication from the handset that there is any power. The battery contacts are all clean.

Re: In Use LED flashing constantly

Your phone may have lost registration to the base. 1) Try disconnecting the power to the base and then re-connecting the power with the cordless phone in the base. Give it a few seconds, then see if it works. 2) Try removing the battery, wait 10 seconds, re-install the battery and set the phone in the charger.

How do I rescue my BT Freestyle 750 from being stuck "Searching" and remedies that are "Not Possible"?

Have you tried removing the batteries and letting the internal power decay for an hour or so - in other words try to get them to forget what they were. Then replace batteries and try again. I guess you've consulted the user manual, is there a reset button hole anywhere on the base unit? The sort you stick a pin into.

Gigaset a420 has stopped making or receiving calls

You mean unplugged it from the power outlet or the RG45 wall jack? OK so if the battery is fine and you unplugged the power from the source, then the issue is with either the cord itself or the charging unit. Just because the little red light comes on does not mean it is working properly. Put a multi-meter on the charging tabs to double check for continuity. Sometimes and as weird as this sounds, it just takes unplugging a nearly spent power pack/inverter to finish the job so to speak. If you unplugged it from the RG45 then you need to look at the pins in the RG45 wall jack to see if you inadvertently bent one out of shape.Phone won't work if there's no signal. Wish I could help more. Good luck with that issue.

Hand set out of range disply is on. How do I reset.

here are some tips from my manual for out of range problems
hope they help
• Only one handset can be used to make or answer a call anytime.
If another handset attempt to do so, the screen will display OTHER
HANDSET ON and then OR OUT OF RANGE. You might press PHONE
or SPEAKER again until no other handset is using the line. Use the call
transfer feature to transfer a call to another system handset
or use the speakerphone feature so multiple members of your
house can be on an active call at the same time.
• Move the cordless handset closer to the base. You might have moved
out of range.
• Ensure that the base is powered up.
• Place the cordless handset in base cradle for 1 minute to allow the
cordless handset and base to resynchronize channels.
• If the cordless handset is in its base and the charging light does not
come on, refer to the charge light is off in troubleshooting guide.
• Reset the base. Unplug the unit’s electrical power. Wait for 15 seconds
then plug it back in. Allow up to one minute for the cordless handset
and base to reset.
• Other electronic products can cause interference with your cordless
phone. Try installing your phone as far away from these types of elec
tronic devices as possible: wireless routers, radios, radio towers, page
towers, cell phones, intercoms, room monitors, televisions, personal
computers, kitchen appliances and cordless phones.

Bought phone EX18560 Series yesterday. floolowed instructions to charge. Today I came home from work, plugged in telephone jack. phone will not turn on. Attempted to re-register (4X's). Led flashes....

I have two older (2002) model cordless Uniden phones that require the handsets to return to their original factory bases. If they have rested on another Uniden base, even of the same model, there is no dialup tone. Replace to the original base and you should be back in service.

How do I add an extension handset to my current config?

IF it was a used handset it was likely registered to another base. I just switched bases (1line to a 2 line base). I had to "deregister" the handsets from the old base. I am not sure if you can deregister if the old base is not present? With the old base plugged into power I hit the "function key" at the bottom left of the handset and scrolled down to initial settings. Under registration is "deregistration". I selected that and it put the handset back to its default out of the box. Then simply hit the mute button on the New base and OK on the handset. Worked for all 5 of my old handsets.

Hope this helps

Base unit light blinking GE 27831

I had the same problem. Once I read the owners manual I found the charge light blinks to indicate that you have voicemail waiting to be retrieved via telecom provider. Much to my surprise I have a voicemail account I never requested.

Another mystery solved - I now know why I missed so many messages.

Vtech phones loosing connection to base

You are pretty close to the solution. The problem is the charge detection in the handset. All handsets on a cordless phone detect the battery level with an hexadecimal value in the memory. Each hex value equal a volt value of the battery. EX: 3.5v = 9B
3.6v = 9C 3.7v =9D etc... The problem is the hex value in your defective handset are all mess up. So 9B is not 3.5v anymore. Then your handset could last 1hr after foul charge or doesn't alert you before the phone goes dead due to low BAtt.
