About Pairing Wireless Headsets
Pairing is the process in which two devices enabled with Bluetooth wireless technology create a secure link in order to share information. The pairing process begins when the master device initiates an inquiry to search for discoverable Bluetooth addresses.
Honeywell wireless headset pairings with Talkman or other devices are initiated by the device and remain paired until broken by user action. Note that the pairing exists between the headset and device hardware. If the operator moves to a different device, the original headset/device pairing does not follow that operator.
Pairing versus Connecting
Pairing is not the same as connecting. Two Bluetooth devices, once paired, can connect and disconnect many times. With a pairing in memory, the two devices can reconnect easily and make repeated attempts to establish a connection. In this way, a headset and device pairing allows for increased user mobility.
For example, if the user takes the headset out of range of the paired device or powers it off, the device notices the connection loss and tries to reconnect. The two remain paired throughout this process.
Pairing-related Configuration Parameters
PersistSrxPairingAcrossPowerCycle
Set to 0 for the device to delete the pairing when it is powered off.
When the device is powered on again, it does not reestablish this connection with the associated headset.
This parameter defaults to 1, which causes pairings to be persisted and re-established when the device is powered on.
When SrxAutoPairEnable is enabled (set to 1), PersistSrxPairingAcrossPowerCycle defaults to 0.
SrxClearPairingInCharger
Set to 1 to clear the pairing when the device is placed into a charger.
This parameter defaults to 0, or maintaining the pairing.
When SrxAutoPairEnable is enabled (set to 1), SrxClearPairingInCharger defaults to 1.
SrxAutoPairEnable
Set to 1 to turn on automatic pairing.
Cross Pairing
Cross pairing is the result of a master device pairing with a headset or other device that is not the intended slave. If a user cannot isolate his or her device and headset from others and a cross pairing occurs, the user should break the existing pairing and retry the intended pairing.
Prevent unwanted cross pairing by isolating the device and headset from all other Bluetooth devices any time that the device is performing an inquiry scan to find the headset or pair manually. Cross pairing is extremely unlikely when a user uses touch pairing.
SRX2/SRX3 Headset Pairing Methods
SRX3 Pairing Modes
After an SRX3 headset enters low or high power pairing mode, it is
available to accept a pairing initiated by a Talkman 700/ A700x
SRX2 Pairing Modes
The SRX2 headset must be in high power pairing mode to pair with a
handheld device. To place the SRX2 headset in high power pairing mode, momentarily press the Plus
(+) and Minus (-).
For pairing with third-party devices: By setting the
SrxHighPowerPairingDelaySeconds configuration parameter, you can configure
how long an operator must hold the Plus and Minus buttons before entering high-power pairing
mode or set the parameter to have the headset go directly into high-power pairing mode. After an
SRX3 headset enters high power pairing mode, it is available to accept a pairing
initiated by a Bluetooth-enabled handheld device.
Pairing Methods
TouchConnect
An SRX2/SRX3 headset and an A700/A700x device can be paired by turning on the device and headset and touching them together. No button presses are required.
See Pairing with A700/A700x Using TouchConnect for a full list of preconditions for using this method.
Recommended for:
VoiceCatalyst users on A700/A700x devices and SRX2/SRX3 headsets
Why?
This method insures that the SRX2/SRX3 headset is only paired with the device it is touching. There are no additional buttons to press.
Auto pairing
On startup or on removal from a charger, the device immediately searches for wireless headsets and initiates a pairing. It eliminates the need to clear pairings manually as it , by default, clears a pairing when powered off or when placed into the charger.
The SRX2 and SRX3 headset always power up in pairing mode.
Recommended for:
- VoiceClient users sharing headsets
- Anyone using SRX2/SRX3 headsets
Why?
When sharing headsets, autopairing makes it easy to locate any device and headset, power the two on in close proximity to one another (less than 3 feet), and have the two pair automatically. It eliminates the need to clear pairings manually or through VoiceConsole as it clears a pairing when powered off or when placed into the charger by default. When you start up the device, it is unpaired and begins searching for a headset. .
Manual pairing
The user determines when to pair a device and headset by pressing buttons on the device.
The SRX2 or SRX3 headset can perform either manual or auto pairing for its first pairing.
Recommended for:
- VoiceCatalyst users on A500 devices
- VoiceClient users not sharing headsets
- Anyone using SRX3 headsets
Why?
VoiceClient users that are not sharing their headsets with other users are encouraged to use manual pairing. Manual pairing is the safest way to avoid cross pairing, as the user is performing the pairing procedure away from other users. Also, once a manual pairing is made (assuming no other configuration parameters have been changed), the pairing persists and that device and headset stay paired until the pairing is explicitly cleared.
VoiceConsole pairing
The user pairs a specific device to a headset via the VoiceConsole interface.
Screen-Based pairing
