Uniden BT230 User Manual

If the noise continues, there may be interference 

on your phone itself, and any noise in the phone’s 

connection will come through on the headset, too. 

Transfer the call to your phone and see if the audio 

quality improves. If it doesn’t, look around for things 

that can interfere with your phone. 

For maximum product life, do not drop, throw, or 

crush the headset. Do not expose it to humidity, dust, 

or temperatures above 125 F.

If necessary, remove the earhook. Dampen a lint-

free cloth with water or a cleaner specially designed 

for electronics, and gently wipe the headset clean. 

Do not expose this product to liquid (water, alcohol, 

etc.) or submerse in liquid for any reason.

Using any headset or earbud at too high a volume can 

cause permanent hearing damage. To reduce the risk 

of hearing damage:

•

•

Set the volume at the minimum level needed to 

hear in the current environment. If possible, use 

your headset in quiet surroundings or try to move to 

an area with less background noise before adjusting 

the volume. 

Start with the volume at its lowest setting, then 

gradually increase it until you can hear.  

Turn the volume down before powering off the 

headset and readjust the volume each time you 

turn it on.

If someone next to you can hear the other end of the 

call through your headset or if your ears hurt or ring 

when you hang up, the volume is too high. 

The longer your ears are exposed to noise, the 

greater the risk of damage. Limit calls at higher 

volumes (or other exposure to loud noise).
