Motorola Automobile Accessories F5218 User Manual

The display, keyboard and CPU Box are designed to operate properly in an ambient 

temperature range of -22°F to 158°F (-30°C to +70°C). The MW810 Mobile Workstation 

CPU must be installed in an area with adequate air flow to allow for proper ventilation. 
Installers must install the CPU in an unobstructed location in order to allow proper air flow 

(see Figure 5). It is imperative to avoid installing the CPU in an enclosure or next to heat 

generating equipment such as: radio transmitters, power amplifiers or a cabin heater.

• Where possible, use existing holes in the fire-wall, the trunk wall and the channels above 

or beneath the doors. Run cables parallel to existing car cables if appropriate.

• When holes must be drilled, verify that other wiring, break lines or gas lines are not 

damaged.

• When drilling a hole in the roof, take care not to snag the roof liner.
• To prevent rusting after drilling, remove all metal burrs and residue, and completely clean 

the area to ensure that all steel dust is removed.
