More about SRX/SRX2 Pairing Modes

When a headset is in pairing mode it is ready to respond to any inquiries about its Bluetooth services. The inquiring
device uses this response to determine if it wants to pair with the headset. Because the device is the initiator and the
headset is the acceptor, a user facilitates the pairing process by putting the headset into pairing mode before initiating
the connection from the device.
SRX and SRX2 headsets support two pairing modes.
• Low Power Pairing Mode
Low power pairing mode is the default pairing mode for SRX and SRX2 headsets. In this mode, a headset will
answer a Bluetooth device inquiry with a very low power response that transmits within a small area (a few feet or
so, depending on the receiving capabilities of the inquiring device).
Limiting the wireless transmission helps to avoid an unwanted cross pairing (a pairing with a Bluetooth address
other than the target) by forcing the headset to be in close proximity to the device.
High Power Pairing Mode
•
High power pairing mode allows the headset and device to be separated by more distance because the headset's
response to inquiries is a wider transmission.
Honeywell recommends using high power pairing only if low power pairing fails. Use this mode with care: While
high power pairing mode makes it more likely that the connection will succeed, it also increases the likelihood of
cross pairing.
If the configuration parameter SrxAutoPairEnable is enabled and the configuration parameter
SrxHighPowerPairingDelaySeconds is set to 0, headsets will skip lower power pairing mode and enter high
power mode.
TouchConnect
•
You can pair an A700 device and an SRX2 headset by touching them. This method essentially eliminates the
chance of cross pairing and it is quicker and easier than the other methods. See
