VoiceStation™ 300 - 8

Clean the VoiceStation™ 300 with a soft, dry cloth.  

Do not use alcohol- or petroleum-based cleaners.

Muffled or “In a Well” 
Reception

► Speak closer to the phone so that 

the microphones pick up your 

speech more accurately.

► Add more sound absorbency to the 

room.

Excessive Noise

► Noisy equipment such as a com-

puter or fan may make it difficult to 

hear the other party.  Both parties 

should turn off noisy equipment.

► Try calling again to see if a differ-

ent line provides a better connec-

tion.

Physical Damage

► If physical damage is severe 

enough that the internal parts 

become visible, disconnect the 

VoiceStation™ 300 immediately.  

► Do not reconnect to the network 

until the VoiceStation™ 300 has 

been repaired.

No Dial Tone

► Check that all connections are cor-

rect and tight.

► Make sure the short cable is con-

nected to a standard analog phone 

line.

► Try a different telephone line.

Phone Does Not Ring

► Adjust the Ringer with the Volume 

up button.

Short Silences, Echoes, or 
Clipped Speech

► Do not move VoiceStation™ 300 

while it is in use.

► Keep your hands away from the 

phone during calls.

► Keep papers, cups, coffee pots, and 

other objects away from the phone.

► At the beginning of a call, allow 

each speaker present to speak in 

turn for a few moments to enable 

the phone’s electronics to adjust to 

the acoustic environment.

► The other party may be using low 

quality equipment or a half-duplex 

conference bridge, in which case 

there is no solution.
