7.8.6 Troubleshooting
The indicators, applications and drivers required to use and monitor the docking
station are installed on the 7530 – no indicators or applications are present on the
docking station itself.

If a network link fails, the 7530 application alerts the operator that the link was
unsuccessful.
7.8.6.2 7535 LED Does Not Light W hen Docked
• Check that the quad dock has power – is the Power LED on the quad
dock illuminated?
• Try inserting the 7530 in another slot in the quad dock.
• Check for dirt or contamination on the docking contacts at the bottom of the
7530. Wipe the contacts with a damp cloth if necessary.
• Check the pogo pins inside the dock cradle for dirt. Gently wipe with a
damp cloth if they appear to be dirty or discoloured.
• Check that the pogo pins are not bent or damaged.
• Remove and reinsert the 7530 in the cradle, and check that the latch is
holding the unit in place (the pogo pins must be compressed for proper
contact).
• Make certain that the battery installed in the 7530 is defective.
7.9 Portable Docking Module (PDM)
Warning: The mains power cord for the DC adapter shall comply with
national safety regulations of the country where the equipment
is to be sold.
The Portable Docking Module (PDM) clips onto the base of the 7530 and is most
often used to charge the 7530 battery when a desktop charger is not convenient. The
PDM also offers additional communication ports, making it useful for upgrading
software in the 7530 from a USB-equipped laptop computer. Figure 7.2 on page 267
illustrates the connectors on the PDM.
