Bluetooth Setup
There are three Bluetooth functions that can be changed in the user setup
screen, Unpair All, Pair PIN code, and device ID.
When Unpair All is pushed, all Bluetooth devices are erased from the audio
panel, and can then be added back as desired. This is useful in some cases
where the unit or operator lose track of the devices paired, and cannot get
them to connect.
Pair: The 4 digit pass code can be changed to any number desired. This is
useful if the owner wants to restrict access to the audio panel Bluetooth func-
tions.
ID: The PMA450 can be renamed using this mode to show up on the devices
with a personalized identifier.
USB Charging Port (10)
The PMA450 contains a USB charging port that is capable of providing 5
VDC, 1.5 amps of current to charge the batteries in smart phones and tablets
used as Personal Electronic Devices. This is NOT a data transfer jack.
