Why do I hear radio communications in only
one ear?
Sierra’s Stereo/Mono DIP switch is probably set
to Stereo while your audio panel is transmitting
a mono signal. To x this, change Sierra’s Stereo/
Mono DIP switch to Mono. This setting does not
aect music or audio from auxiliary devices; you
can hear stereo sound on auxiliary devices even
when the Stereo/Mono DIP switch is set to Mono.
When pairing Sierra with my Bluetooth phone,
why does my phone indicate it cannot connect?
The headset may not be in pairing mode. To enter
pairing mode, you must start with Bluetooth mode
turned fully OFF; (see “Connecting Bluetooth Cell
Phones for the First Time,” on page 10).
Why doesn’t my Bluetooth phone accept
Sierra’s 0000 passcode?
Your headset may not be in pairing mode. Some
phones prompt for a pass code without checking
for pairing mode. When the phone cannot pair
with the headset, it rejects the passcode. To enter
pairing mode, you must start with Bluetooth mode
turned fully OFF (see “Connecting Bluetooth Cell
Phones for the First Time,” on page 10).
How can I reduce static noise during cell
phone calls?
To reduce RF interference during phone calls,
keep cell phones at least 12 inches from the
Sierra controller and headset when making calls.
