In standby mode, you can adjust the ringer volume by using the Volume Control V- or V+ on the right side of the phone. The display will show the current level. For example: Volume 3. You will also hear the audible ringer at each level you select.
Visual Ringer & Shaker Option
Your phone is equipped with a bright LED light that can flash a very bright light when the phone rings. If you have selected the LED light to be ON, it will flash on all volume levels.
Your phone is equipped with a 3.5mm vibrating alert jack for an optional bed shaker (purchased separately) to alert you when the phone is ringing. Simply plug it into the shaker jack and place it between your mattress and box spring or under the cushion of a chair. When the phone rings, the pad will vibrate with each ring of the phone.
