8 - 8 MC75A Enterprise Digital Assistant User Guide
Single Slot USB/Serial Cradle
When trying to 
connect a Bluetooth 
device and the 
MC75A, the device 
thinks a previously 
paired MC75A is 
used.
The device 
remembers the 
name and address 
of the MC75A it last 
paired with via the 
Bluetooth radio.
Manually delete the pairing device and name from the device. Refer 
to the device’s user documentation for instructions.
There is a delay in the 
Bluetooth stack 
re-initializing during a 
resume from 
suspend.
This is normal 
behavior.
No solution required.
The Bluetooth 
connection drops.
The MC75A 
suspends and the 
Bluetooth radio 
power turns off.
When the MC75A suspends the Bluetooth connection is dropped. 
Re-connect the Bluetooth connection when the MC75A returns from 
suspend mode.
