Trying to find out what my pass key is for my motorola h300 wireless headset

the password is 0000

passcode 0000

if you never reset it when you purchased it try using the code 1111, or 1234 or 2222, etc shouldnt go higher than 5555...those are Moto's default sec settings. hope this info was helpful:)

try 0000 (four zeros)
it is normally the default

the pass key is 0000

With the headset power off, press and hold
the Call button for 6 to 10 seconds until the
blue indicator light turns on and remains
steadily lit. (The light will flash while you

remain steadily lit, turn off the headset and
repeat step 1.
