We Have Incorrect Pairings And Rf Interference; Troubleshooting Wired Scanners - Honeywell A700 Hardware Reference Manual

Some scanners power down to conserve battery power which includes powering down their
Bluetooth radios. When the radio turns off, the pairing with the Talkman device breaks. Some
scanners may also disassociate any pairing by default after a power-down meaning that the
scanner needs to be manually re-paired on power up.
Similarly, some scanners have parameters associated with the length of time that they will
maintain a Bluetooth radio connection.
Resolutions:
Review and change the scanner's power management options from the default behavior to
ensure that there is no delay in scanning caused by any disconnect/reconnect. Usually these
options are able to be changed by an initial configuration of the scanner.
Alternatively, change the scanner's connection maintenance parameters that cause the scanner
to disconnect after a fixed period to ensure that the scanner stays permanently connected.
Refer to documentation from the manufacturer for additional settings.

We Have Incorrect Pairings and RF Interference

Scenario:
An operator cannot pair her scanner with a Talkman device that was previously paired to a
l
different scanner.
Operators experience random cross pairings (scanners pair with unintended Talkman
l
devices).
RF transmissions in the workplace fail as a result of radio interference.
l
Possible Causes:
If a scanner remains paired to a Talkman device when work is completed that persistent
connection could interfere with another user trying to use that Talkman with a different scanner.
The scanner will also try to re-pair by paging or sending repeated bursts of Bluetooth radio traffic
through the air. This spurious Bluetooth RF can interfere with other transmissions.
Resolutions:
Honeywell strongly recommends that operators unpair scanners and Talkman devices when they
are finished using them.
1. Break the pairing between scanner and Talkman.
2. Pair the scanner with its base station, or set the scanner to acceptor mode.
These actions ensure that no random pairing will interfere with new pairings and that unpaired
scanners will not "page" and interfere with other RF transmissions.

Troubleshooting Wired Scanners

If the scanner does not pair or appear to work:
1. Be sure that the scanner is on, Talkman is on and Talkman battery is charged and that the
Talkman task in use is one that is set up for scanning.
