Volume Control
The dial controls the level of volume the handset and headset receive. The volume dial provides up to 15 decibels of volume before the CLARITY POWER button is activated. Once the CLARITY POWER button is pressed, the C4205 will provide up to 50 decibels of amplification.
Tone Switch
Adjusting the TONE switch allows you to customize your hearing experience. Since we all have different hearing preferences we suggest exploring each setting to find the one most comfortable for you.
Handset Ringer
Set the switch marked Ringer OFF/VIBE/ON located on the side of the handset. When VIBE is selected the handset will ring and vibrate when receiving an in- coming call. The ringer switch must be set to ON or VIBE for the handset to ring.
NOTE: If both handset and base ringers are set to OFF, the visual ringer will flash to indicate there is an incoming call.
