Important Safeguards and Warnings.
The battery should be disconnected from the vehicle before working on the electrical system of the vehicle when installing,
servicing or removing Gatekeeper products.
All Gatekeeper employees or contractors who preform electrical work (install, service or remove a DVR, installing a
backup camera system for example) on a customer vehicle shall ensure that the battery in the vehicle is disconnected
before work commences.
Customers shall be responsible for addressing any systems on the bus that require attention as a result of disconnecting
the bus battery. This includes, but is not limited to, entering a radio theft code, programing radio stations etc.
Remove Main Power Fuse or Disconnect Vehicle Batteries Prior To Any Electrical Work Or Jump Starting The Vehicle.
Firmware updates (available from www.gatekeeper-systems.com when released) are system specific, firmware updates
must only be applied to the 816-HD system. If this firmware is applied to any other Gatekeeper Systems DVR warranty
will be void.
The 816-HD has an operating temperature range of -40° C to +65° C. It is good practice to ensure that the 816-HD is
mounted in an area in which acceptable temperature ranges are experienced.
Do not remove the cover of the 816-HD series as this will void any warranty.
When a system has shipped with a GPS antenna, ensure that the GPS antenna is mounted externally on the roof of the
bus, magnetic side down.
Do not format the COMRAD™ HDD using Microsoft Windows.
