Dear Tzippyz, Probably the mic is disconected or misplaced. If you have the right tools try opening the phone and have a look.

The Motorola H700 has Bluetooth v1.2 which is backward compatible with v1.1. The headset works with both Hands-free and Headset profiles and is easy to pair with devices running various operating systems and software. We tested the headset with the Motorola SLVR, Palm Treo 650, the Nokia 9500, the Cingular 8125 and the Cingular 2125, and the headset paired with all devices with ease. To pair the Motorola, turn off the headset first then hold the Call button until the LED ring turns purple, quickly open the boom so that the LED stays solid purple, the headset is now in pairing mode. Use your mobile phone to discover and pair with the headset using “0000” as the default pass code. Call handling between the phone and the headset transferred smoothly and the headset will play notification or a ring tone when a call comes in. When working with the Treo 650, the H700 has an uncomfortably long delay in notifying an incoming call. It starts to ring after the Treo 650 has already ringed 2-3 times. The connection between the phone and the headset is solid. When we paired the Treo 650 to both the Motorola H700 and the Parrot 322 car kit, we can pick up calls on either one and the Motorola H700 worked reliably in this set up.

Hope I helped Dr Reed

Go to systems "Phone" and make sure that TTY/TTD mode is not turned on. This can cause the phone to have the symptoms you describe.

Palm treo 650 phone

Greetings to all. I have just purchased a palm treo 650. It was unlocked so I was told, but it was not a GSM, It was a CDMA, My carrier is T Mobile and I dont know what I could to Make It Work, as t mobile has a sim card and this treo 650 does not. Is there any thing I could do to solve this problem?

No speaker no sound on my treo

I had to have my Treo swapped once already because of a problem with the headset jack. The same problem is happening now - the phone always thinks the headset is plugged in (even when it isn't). That results in phone ringing (unless on virbate / silent mode) but no audio through the speaker in the back, and no speakphone icon appearing.

Given the symptoms you describe I would go to your service provider and (hopefully) get support under warranty - very likely hardware related.

Lost speaker on my Treo 650

This problem usually occurs when the headset jack is busted. If there is sound through the headset but none when you plug it out, then a busted or faulty headset jack is definitely the culprit.

LG HBM-730 Won't Connect to Treo 650

Actually it's a Treo 680. Finally took the battery out of the phone. That seemed to clear everything so that I pair the bluetooth with no problem.

Palm treo 650

The 650 seems to have a delicate headphone/mic jack. Dropping the phone, even gently, seems mess up that jack. I returned my first treo 650 as defective, and got a new one. The same thing happened to my new 650 after I simply compressed the phone in my breast coat pocket by holding my mail against my chest.

I can't get a new one because the replacement treo comes with no warranty of any kind. :(

My advice would be to find a PDA/phone repair service to repair the jack or diagnose the problem if it turns out not to be the jack.

Treo 600 can't hear without headset

Try blowing hard on the spot where the headset plugs in. I have this same issue on my treo and a good burst of air will at times bring back the speaker/microphone.
