Motorola V810
Speakerphone with V810 feature instructions
WHEN CONNECTED---push the o.k.. button for 1 second and it will prompt you with a request for use of speaker phone. Softkey Left (top left) is for yes and Softkey Right (top right) is for no. To go back to regular phone to ear placement just push the o.k.. button again. That's it.
With the proper volume setting and adequate distance, your caller will not even know they are on speaker phone. This particular feature of the V810 is top notch and one of my favorites.
Keep in mind that battery usage increases dramatically with speaker phone use since it requires extra juice to power the external speaker. Hope this helps.
