I hope this thread can provide updated information on the potentially abnormal or problematic sounds that some, many, or all Razr V3's seem to make.

There appear to be two distinct sounds. First, a low toned buzzing or humming sound coming from the keypad area. It seems as though all Razr's make this first sound, though not all Razr users notice it. The sound seems linked to the lighting mechanic(s) for the keypad. So far as I know, Motorola nowhere officially acknowledges this sound, or whether this sound is normal, common, etc.

The second sound is a more high pitched ringing sound coming from the display area. It seems as though not all Razr's make this sound. I have found two units that did not make this sound initially when new, but began to make it within a few days. This second, higher pitched sound is basically constant whenever the display is lit - with a few exceptions, eg, when dialing/sending out a call/number, the high pitched sound stops temporarily, even though the display is still lit. So far as I know, Motorola nowhere officially acknowledges this sound, or whether this sound is normal, common, etc.

Does anyone have any updated information on these sounds? For instance, do the sounds change over time? Do they get louder as the phone gets older? Has anyone seen any piece of writing in which Motorola makes any comment on either of these two sounds? If so, where? If not, does anyone have hypotheses about why not? One hypothesis is that Motorola does not publicly address the issue because not enough people are bothered by the issue for it negatively to lower sales and a written statement about one or two sounds that bother some people but not others might lower future sales.

I still really like my Razr, but I would like it even more if it did not make these sounds. In addition, it might be nice for Motorola to make some comment on the sounds - eg, we should expect them both as characteristics of the phone/design, we should expect one sound but have the phone repaired/adjusted for the other sound, etc.

Does anyone have any updated information on this topic?

I've only had this phone for less than a week and it bothers me that there is that buzzing sound. It feels like there is a slight current going on when I use. It is just weird. I am hoping that it doesn't cause cancer (what else doesn't, right?) or something horrible like that. icon_ermm.gif

I am not sure whether to return the product and get something else. I'm giving it a week to test before I decide. Has anyone tried to contact Motorola about it yet?

I've gotten used to the two sounds, and they don't bother me anymore. My main complaint about the phone is that, although it has an excellent speakphone, I find that the ear-speaker-volume is too low to use in public. But I don't like to chat in public anyway. I find the phone to be pretty rugged/sturdy, as well as light/thin to fit in a pocket.

I believe burnsey is referring to this document I believe to have been released by Cingular regarding Razr V3 "buzzing":


Product Note: Motorola V3 RAZR Keypad And Speaker Noise -All Markets
(COR, DMDR, Indirect Internal/External)
Some users of the Motorola V3 RAZR may hear a hum or a high pitch tone emanating from their device at certain points during use.
(Mon, November 07, 2005)
Issue/Volume number: 1

OVERVIEW

Both of these sounds can occur as part of the normal operation of this device and are NOT an indication of a problem or defect in the unit.



NOTE: No warranty exchanges should be executed for either issue if consistent with those that occur during the normal operation of the device.



CRITICAL, MUST KNOW/MUST DO

With normal use of the device these sounds are commonly heard when:

* (Tone) The phone is held near the ear before making a call. When a call is active the software in the phone changes the frequency of the tone to one at or below the low end of the normal audible range (Please note that persons with sensitive hearing may still be able to hear the tone).
* (Hum) The keypad is held close to the ear (much closer than in normal calling position). It is due to the inherent properties of the electro-luminescent backlights used in the product.



Customer / Embedded Base Resolution:

If a customer requests assistance or an exchange due to the buzz or high pitch tone from a V3:



1. Verify that noise or tone is consistent with normal operation by:

A. Tone in speaker: Verify the tone is eliminated or reduced to a non-distraction level by placing the unit on a call and listening via the earpiece speaker.



B. Keypad “hum”: Listen to the keypad when the backlights are active. Wait until backlight times out. The “hum” should follow action of backlights



If you determine that the sounds are consistent with these known occurrences, NO exchange is warranted.



2. If found to be inconsistent with normal operation, then proceed with standard troubleshooting / exchange processes.



ACCOUNTABILITY/RESPONSIBILITY

Identify customers impacted by this issue and follow appropriate procedures.
