Eliminating Interference
If the device does not function as expected, first check whether ambient interference is present.
If there is no ambient interference present, check the connections of the handheld and the mo-
bile terminal device for faults.
If there are no faults, there is a device malfunction. Device faults may be caused by several
factors:
n
The handheld is not charged. If the charge state is too low, communication faults can occur
between the handheld and mobile terminal device. Charge the handheld.
n
The firmware of the handheld is obsolete. Carry out a firmware update.
n
The audio port of the mobile terminal device is dirty. Clean the audio port.
