INTRODUCTION
NOTE: Zebra technologies Corporation is not liable for personal injury or damage to
any equipment caused by the improper installation of this equipment to any power
source.
The MMQ4 Mobile Mount system is designed to integrate a Zebra™ QL 420 Printer and a
Zebra RCLI-DC Mobile Charger into the electrical and mechanical systems of a vehicle.
Once installed it will provide intelligent charging capabilities for the printer’s battery and
protection from accidental damage to the printer.
The RCLI-DC series of Mobile Chargers are supplied separately from the Mobile Mount
installation Kit. They should be installed in accordance with their installation guides and
under the supervision of properly trained and qualified personnel. The following installation
instructions pertain only to the mechanical installation of the MMQ4 mobile mount. Follow
them closely to ensure safe, reliable performance of the QL 420 Printer in a mobile
environment
The printer is powered with its own battery which is charged by a RCLI-DC Series Mobile
Charger System which runs off the vehicle’s DC electrical system. Refer to the RCLI-DC
charger installation Guide for more detail on their use and installation.
It is important that the vehicle’s electrical system be functioning properly. The vehicle’s
charging circuit must work properly and vehicle-generated electrical “noise” must be
minimized and within specifications.
The vehicle charging circuit must neither undercharge nor over-charge the vehicle battery.
Defective ignition wiring, damaged insulation, or faulty vehicle electrical components can
cause electrical noise and excess electrical noise can be severe enough to defeat the
electrical filtering that is built into the printer. When this happens, computers and printers
can behave unpredictably.
NOTE: All of these systems must be connected in strict accordance with the
instructions in this document. Failure to install this equipment per these instructions
will void the warranty.
