OPTIONAL EAPRHONES
Although the BTH-500-VOX has a built-in speaker for listening to received calls, some users may prefer to
use a listen only earphone for enhanced privacy. The accessory jack on the speaker microphone will accept
any mono earphone with a 3.5 mm audio plug. When an earphone is used, the front-firing speaker is
disabled.

the phone. Re-establishing this connection can take 10-60 seconds.
In the event that the phone and speaker microphone to not automatically reestablish their link,
simply press the phone button on the BTH-500-VOX to restore the connection.
