Diagnosis
WE BLE MISS error
Check transmitter battery
power
Check for other devices
using the 2.4GHz band
that may be causing
interference
If other 2.4GHz devices
have interference
problems (e.g. Bluetooth®
headset) there is likely
interference.
Intermittent or complete
loss of signal
Swap transmitter(s)
with known-good
transmitter(s) and pair to
the receiver
Swap receiver with
known-good receiver and
pair to the transmitters
Wireless edge
intentionally removed
Check cable between
receiver and powerhead
main board for
disconnection or damage
to the cabling.
Power cycle the operator
completely. If the power
cycle does not resolve
the issue, restore factory
defaults settings and
reconfigure the operator.
Replace the receiver
module with a known
good unit.
Temporarily remove
other accessories from
between the wireless
edge receiver and the
powerhead main board
58
Resolution
Pair transmitters to the
receiver
Replace batteries
Reduce 2.4GHz band
congestion
Shorten distance between
transmitter and receiver
If a known-good transmitter
resolves the issue, replace
the bad transmitter
If known-good receiver
resolves the issue, replace
the bad receiver
If the wireless edge is no
longer wanted, it can be
unlearned from the safety
devices menu by using the
LCD wall control.
Correct any issues or replace
any faulty parts.
If the steps listed in the
diagnosis resolve the issue,
there may have been a
transient condition that
caused and issue that was
resolved. If the issue occurs
excessively, the problem may
lie elsewhere.
If the problem is resolved,
replace the receiver with a
new one.
If the known good unit still
does not work, replace the
powerhead main board.
If issue is resolved, add
accessories back one by
one to find the accessory
that causes the issue, then
troubleshoot that device
